About Buoy SoftwareOur mission is to deliver the best experience possible to as many donors of blood products (such as plasma) as possible, in as many communities as possible. We use our understanding of blood product donation and the industry’s regulations and pair them with our extensive consumer product experience to enrich the lives of our members and improve health outcomes for patients everywhere. In an industry that hasn’t seen innovation in more than two decades, Buoy’s software streamlines the donation process allowing our business to promote loyalty while improving efficiency in a donation center.

About GFX Labs

Based in Chicago, GFX Labs is a research and development company founded in 2021, dedicated to pushing the boundaries of decentralized finance (DeFi). The company designs and builds cutting-edge tools and platforms for financial services, on-chain data integration, and professional trading experiences. Beyond product development, GFX Labs plays a key role in DeFi governance, contributing to the evolution of major blockchain protocols. With a mission to innovate and democratize finance, the company collaborates with regulators and industry leaders to shape the decentralized financial ecosystem. Its team of experts is committed to delivering impactful solutions for the future of blockchain-based finance.

GFX Labs operates two distinct isions. Our primary ision focuses on Oku, our comprehensive DeFi application. We have partnered with the Uniswap DAO, the leading decentralized exchange, and recently announced a collaboration with Morpho to integrate borrowing and lending into Oku.

Our second ision is dedicated to research and development. This work spans various areas, including analyzing the economic safety of on-chain financial mechanisms, designing user experiences, and indexing data for integration into existing products. The GFX team possesses a wide range of skills and has a strong track record of delivering high-quality services to industry-leading organizations.

Why work at GFX?

• Any firm can pay a high salary and offer good incentives (as will we), but most can’t offer interesting, challenging, and rewarding work.

We are going to make mistakes, and we are going to build a better product because of them. We don’t micromanage or have a huge team of product managers. We want self starters who take charge and solve problems.
• We don’t care if you went to school, what grades you got, or your age. Show us what you have built, what problems you have solved, and what skills you have.

About Us

Close is a bootstrapped, profitable, 100% remote, ~100 person team of thoughtful iniduals who prioritize taking ownership and making a meaningful impact. We’re eager to make a product our customers fall in love with over and over again.

We 💛 small scaling businesses. Since 2013, we’ve been building a CRM that focuses on better communication, without the hassle of manual data entry or a complex UI. We are out to supercharge sales productivity with the most modern, thoughtfully designed, all-in-one, communication-focused CRM. 

Our backend tech stack consists primarily of Python Flask web apps with our TaskTiger scheduler handling many of the backend asynchronous task processing chores.

Art+Logic is looking for Senior Python Web Developers to work with us on interesting custom software projects. We’ve been an all-remote company since day one—more than thirty years ago.

Our ideal developers thrive in the environment of variety and challenge that is inherent to custom software development, working with us in a long-term relationship over many projects for numerous clients.

The skills and needs for each project we tackle can vary widely; this goes beyond just the languages and technologies we use, and extends to the industries and problem domains we work in. We love working with developers who are excited to learn and take on new challenges. You can expect to grow in your strength and your versatility at Art+Logic and we want to help you do so.

We work completely remote. We expect you to be able to work with minimal supervision and comfortably with small teams of 3-8 people. You won’t have someone looking over your shoulder, so you'll need to be communicative and reliable, and hold yourself accountable.

We value work/life balance, and our projects keep meetings to a minimum to ensure everyone has the flexibility to work during the times that work best for them. We are looking for contract developers able to commit between 30 and 40 hours a week most weeks, and we never expect our developers to consistently work more than 40 hours in a given week.

Art+Logic is run by humans, who work and create using technology. Things can go wrong and we need to respond to the unexpected by being kind, considerate, fair, flexible, and calm. We treat our clients and peers as respectfully as we ourselves would like to be treated.

This position pays between $30-$40 USD/hour.

**Qualifications

• 5+ years of Python experience in a web development context.
• 5+ years of JavaScript front-end development.
• Deep knowledge of Python 3.
• Experience with Vue.js or React.
• Excellent verbal and written communication skills in English.
• Experience with Django and SQLAlchemy is a plus.
• Experience with AWS and AWS lambda is a plus.

**

We are looking for Contractors (1099) for long term open-ended relationships, which includes company to company positions. Work hours are flexible; requiring reasonable overlap with normal US working hours to support team communications, and not just nights and weekends. 

Our rates range from $30-$40 USD/hour. 

We are ONLY looking for people in the United States, Canada, Mexico, Central America, South America, and the Philippines.

It’s important to us in the hiring process that we allow developers to demonstrate their abilities by actually developing something, because a list of previous employers or educational background aren’t always indicators of what someone can do. All applicants are asked to submit a solution to a programming challenge that emulates a task we might assign on a project. 

We have an asynchronous Recruiting Process which means we are always looking for great programmers that we’re excited to work with, without an immediate, specific position or opening in mind. Successful completion of our challenge and process leads to us looking for an opportunity for us to begin working together. This also makes our Recruiting Process very flexible, though we are not usually a good fit for those needing immediate work.

MANUAL is a digital personal development and mental wellness platform designed to inspire young men to become the best versions of themselves. Today, male students are far less likely to be enrolled, retained, and graduate from higher education institutions, and this is especially true for young men of color. Their mental health outcomes are rapidly worsening, with young men dying by suicide and overdose at alarming rates.

MANUAL works with high schools, universities, and fraternities across the country – including the University of Mississippi, Morgan State University, and MSU-Denver – to solve this challenge, bringing high-quality men's success and mental health programming to tens of thousands of students. MANUAL has raised capital from Expanse Venture Partners, 12-48, the Inner Foundation, and angel investors from companies like Maven Clinic, McKinsey & Company, Eleanor Health, and more. MANUAL’s evidence-based approach has been proven to enroll young men who are not currently being reached by existing services, and users report significant levels of trust towards the service.

Are you passionate about crafting efficient and scalable applications? Do you want to use your skills to help thousands of young men around the country? If you're enthusiastic about full stack Typescript, and love the thrill of a startup, we’d love to talk to you!

We're not in a position to provide the support and mentorship a junior developer needs (ex. fresh out of college or dev bootcamp), so you should have experience shipping production code.
• A formal education in computer science. We recognize the value of erse educational backgrounds and learning paths. Our head of engineering, for example, doesn't have a computer science degree.

**

• Lead the development of our RedwoodJS backend, which provides APIs for our NextJS and React Native apps. Most of your time will be spent working on our APIs - adding new features, improving tests, optimizing performance, etc.
• Assist in the management of our Postgres database and backend infrastructure.
• Engage in user feedback sessions to directly learn from our users and adapt our solutions to better meet their needs.
• Be involved in the hiring process for future engineering team members, helping us grow our team with talented iniduals.
• Play a pivotal role in defining our engineering processes and culture.
• Collaborate closely with our head of engineering and other team members on a variety of backend and frontend projects, contributing your unique skills and perspectives.

• You submit your application, if we select you for an interview we’ll reach out to schedule…
• 30 minute intro call with Karl Morand, our head of engineering. This call will be focused on getting to know you, your background, experience, and answering any questions you have about MANUAL or the role. We won’t get into anything super technical (no live coding or anything like that). A list of some topics/questions will be provided to you before the interview - the goal is to see you at your best, not test your ability to remember anecdotes from your past under pressure.
• Take home project is the next step. You will have at least 5 days to complete the project. The goal of the project isn’t to nitpick your code, but rather to give us a starting point to discuss how you approach solving problems with code.
• 45 minute technical call with Karl Morand, our head of engineering. In this call we’ll use your take home project as the basis of our discussion on how you approach solving problems. All candidates who complete the take home project will advance to this stage. This call will include a more detailed discussion of your technical experience and knowledge. Specific topics of interest will be provided to the candidate when the interview is scheduled. While this call is more technical in nature, there is still no live coding.

At Silverfin we’re trying to apply the promise of software to the age-old industry of accounting. With our SaaS we’re automating a large chunk of the busy-work that accountants are currently handling manually, and are building new tools so they can provide better services to their customers. We aim to optimise their workflow in such a way that accountants can spend more time on the much more impactful and rewarding work of advising their customers, the business owners.

The good news is we’re succeeding in doing exactly that. Every week more than 15.000 financial service professionals use Silverfin to help and advise more than 400.000 businesses. Our customers adore us! The even better news is there’s still plenty left to work on, and that’s where we hope you come in.

**

The Silverfin engineering team consists of two main types of teams. A product team is a cross-functional team where engineers work together closely with product managers and product designers. The team's input comes from users or from a business problem that it can solve with a high degree of autonomy. Product teams are supported by a handful of platform teams that focus on the application's architecture and stability, while providing internal tooling and APIs.

Our ops team ensures things run smoothly, deploys happen correctly, and will work with you when issues should arise. We’re enthusiastic followers of the devops mindset, which means ops and developers work together to solve problems, and empower each-other to be self-sufficient, instead of throwing problems over the wall to the “other side”.

We run an up-to-date Rails monolith on the backend, with PostgreSQL and Redis for persistence and caching, and everything is running on a Kubernetes cluster in Google Cloud. Our daily tools include GitLab, Quip and Slack, with Zoom as our remote conferencing tool of choice. 

No code gets deployed without a code-review by a peer and testing is a must. Our pipeline automates deployment when the suite is green, and deploys happen dozens of times a day. Each team is currently doing Kanban, but they’re free to follow whatever process suits them best. There are regular retros held to work towards continuous improvement.

Software for accountants is not considered to be very exciting, but we have our fair share of technical challenges. To give you a sense of scale: our database exceeds 17TB*, and our largest table has crossed the 10 billion row mark a long while back. We interface with more than 40 different external APIs, and provide third parties an API of our own.

*: Our ops team noted that this actually isn’t that hard to achieve if you’re just indexing everything, but it still sounds impressive, right?

**

We’re a remote-first engineering team of 40 people distributed in 14 different countries over two continents. A priority for us is maintaining proper work-life balance. We avoid meetings as much as possible, accept deadlines only when absolutely necessary, and never expect anyone to work longer hours than they’ve signed up for. A day in our working lives is pretty boring, and we feel that’s exactly how it should be.

Working with us means you can be flexible with your schedule. It’s OK to disappear for a few hours in the middle of the day to run some errands, get a haircut, pick up the kids - whatever reason, you don’t need to explain yourself. You also fully decide when you take time off: our team is sufficiently varied and well organised that there are always enough people around to handle the load, and in the rare cases it’s not, we will decrease the load instead of asking people to move their holiday.

Being remote-first means we favour asynchronous communication. We don’t shy away from chatting in Slack, but the important decisions or discussions are done in Gitlab issues, over email, or in Quip, so there’s a written, persisted record. We’re mindful of maintaining long chunks of focussed time, which means we avoid @-mentions or PMs on Slack, and other triggers and interrupts. We encourage using Slack’s DnD function, especially when you’re not working!

We’d be really happy to welcome you in our #engineering channel, but it’s not just virtual: we make sure we regularly get to see each other in real life too. Twice a year we fly the whole engineering team together to a different location in Europe, and at least once a year we join up with the rest of the company so we can spend some time together with the other departments.

**

Personal growth is key to staying motivated. Our team of experienced engineers is there to mentor you and help you hone your craft and improve as an engineer. You will have a chance to get to know and work with a state-of-the-art software development workflow on a real life Rails app at a large scale..

It's also good to know that later on at Silverfin you don’t need to move to management in order to advance. We see the inidual contributor track and the management track as two different growth paths which every engineer can follow and switch between. You can be promoted, including pay raises, as a contributor or as a manager.

Everyone gets a €1200 yearly budget to spend on conferences, courses, workshops or other training to improve their skills and level up. This also includes accommodation and travel costs. If the conference is on a workday you’ll get paid like any normal day.

**

• You have at least 2 years of experience working with Ruby, or 1 year of experience with Ruby and 3 years in one or more other programming languages
• Your work hours have some overlap with EU business hours (we require your local timezone to be within CET +/- 3h)
• You can communicate clearly in English, both in writing and verbally

Nice to haves

• These would be nice but are definitely not necessary. Don’t worry if none of the following applies to you.
• Experience as a remote worker in a fully remote team
• Experience working with large datasets and the problems they bring
• You have some experience using Javascript framework(s), understand the value of them, but also know when plain Javascript is enough
• Experience in Fintech
• Accounting knowledge

Since November 2023 we are proudly part of Visma - the European leader in mission-critical cloud software, enjoying the power of the Visma brand and resources whilst retaining business autonomy and go-to-market freedom.

One of the cornerstones of the Silverfin platform is the integration with bookkeeping software that accountants already work with, which allows us to seamlessly import their accounting data. We currently have integrations with over 40 different vendors, and we want to add more as we expand to different markets.

Team Syncs is the team responsible for creating, maintaining and improving these integrations. Some APIs we need to use are poorly designed, badly documented or unreliable, and it can be challenging to build a robust integration. Yet solving those puzzles, and empowering our customers by importing gigabytes of data from their clunky bookkeeping software, makes it all worth it. Because once the data is in Silverfin, it's connected, standardised and can be easily worked with, which is what it's all about. If you're a tinkerer, love working with APIs and thrive in the face of uncertainty, this might be for you. 

What are the things you'll be working on?

• Improve the stability, performance and infrastructure cost of dozens of our current 3rd party integrations, through usage of different distributed systems patterns
• Practise your modelling & refactoring skills. You'll have the opportunity to think about solutions that will be applied in over 40 of our integrations
• Help design & build the new generic API based on more than a decade of our experience with building custom solutions for bookkeeping software
• Rare opportunity to work on a CLI/service application which is currently deployed on hundreds of our customers' servers 

**

There are seven engineering teams working together to deliver the best value for our customers. Several product teams, collaborating closely with product managers and product designers, are solving customer facing problems. The other, more platformy teams, own complex subsystems, like syncs or AI, and or support the product teams with knowledge,  frameworks and services. 

Our ops team ensures things run smoothly, deploys happen correctly, and will work with you when issues should arise.

Our product teams are cross-functional teams, with engineering, product design, and product management represented. They work very close to the users, trying to understand their problems and then discovering and implementing solutions that add the most value. We believe in very close collaboration between the three perspectives as early in the process as possible. The product teams are supported by other teams that provide core services, maintain complicated subsystems, or possess specialised expertise. 

We're proud of our in-house AI team, which is focused on the application of the newest developments in machine learning to address our users' most important challenges. We’re pretty far on that journey already, since we have multiple AI-powered features that are solving actual client problems and are commercially successful. 

Our CloudOps team ensures things run smoothly and will happily work with you when issues arise. We’re enthusiastic followers of the DevOps mindset, which means ops and developers work together to solve problems and empower each other to be self-sufficient, instead of throwing problems over the wall to the “other side”.

We’re a remote-first engineering team of 40 people distributed in 14 different countries over two continents. A priority for us is maintaining proper work-life balance. We avoid meetings as much as possible, accept deadlines only when absolutely necessary, and never expect anyone to work longer hours than they’ve signed up for. A day in our working lives is pretty boring, and we feel that’s exactly how it should be.

Working with us means you can be flexible with your schedule. It’s OK to disappear for a few hours in the middle of the day to run some errands, get a haircut, pick up the kids - whatever reason, you don’t need to explain yourself. You also fully decide when you take time off: our team is sufficiently varied and well organised that there are always enough people around to handle the load, and in the rare cases it’s not, we will decrease the load instead of asking people to move their holiday.

Being remote-first means we favour asynchronous communication. We don’t shy away from chatting in Slack, but the important decisions or discussions are done in Gitlab issues, over email, or in Quip, our central wiki, so there’s a written, persisted record. We’re mindful of maintaining long chunks of focused time, which means we avoid @-mentions or PMs on Slack, and other triggers and interrupts. We encourage using Slack’s DnD function, especially when you’re not working!

We’d be really happy to welcome you in our #engineering channel, but it’s not just virtual: we make sure we regularly get to see each other in real life too. Twice a year we fly the whole engineering team to a different location in Europe, and at least once a year we join up with the rest of the company so we can spend some time together with the other departments.

**

Personal growth is key to staying motivated. As a manager in Silverfin you will participate in our initial Leadership Development Program and regular Leadership Days.

In addition to that, everybody gets a €1200 yearly budget to spend on conferences, courses, workshops, or other training to improve their skills and level up. This also includes accommodation and travel costs. If the conference is on a workday, you’ll get paid like any normal day.

Scroll is looking to hire a Senior Technical Support Engineer to join their team. This is a full-time position that is 100% remote with no geographical restrictions. Work remotely from anywhere.

We're looking for a senior rails developer to come work with us at WodBoard  WodBoard is gym management software that helps gym owners run their businesses and helps their customers, the gym members, live healthier lives.  The brand name won't make any sense unless you've walked into a functional fitness gym before so I'll move swiftly on...

We're a bootstrapped company so there's no VCs to answer to.  That doesn't mean we're not ambitious though - there's a massive market we're going after and we want to create lasting change.  As a combination of these two things we've a heavy focus on getting stuff done.

Our development ethos could be best described as "full DHH". Whilst there's some bits we don't 100% agree with we stick to the core Rails ethos and stack, focussing on what we can achieve with the technology, rather than the technology itself.  If you've enjoyed some of the blog posts on how Basecamp structure code, or enjoy the work of boringrails.com, you'd like working with us.

We're a small (but mighty) tech team of 3 so you'll be jumping straight in and writing code for customers from day 1. There's also infrastructure/UI work/mobile app development work that happens and you can become involved in if you so wish.  The role has the opportunity to build into a CTO role for the right person.

A little more about the role and us:

• It's really refreshing using technology to do something that helps people in a real world tangible way.  Changing lives and increasing health through technology is very motivating!
• We love simplicity.  We're fanatical about it.  This goes from our codebase, to our infrastructure, to how we operate as a company.  It can be harder work upfront but it sure makes life easier down the road.
• You'll need strong ownership skills.  As a small team we don't have project managers.  You're responsible for your tasks so you'll need to be good at taking ownership and reporting back to the team.
• An ability to renegotiate requirements as you get into the technical details is most welcome!  In Computer Science there's hard problems and hard problems that don't need solving.  We are constantly asking ourselves if there's an easier way to do something.
• We spend a lot of time talking to our customers and understanding their problems.  This won't ever change.  Be prepared to go back and evaluate previously held assumptions on new features after testing with beta customers

The position is fulltime and by no means do you need to be into health/fitness to work here (only about 50% of our staff are).  It's fully remote position but you'd need to be on an EU timezone so there's sufficient overlap with the rest of the team.  We also do a full team meetup in person twice per year.
