All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.

Why should you join Secfix?

Secfix is an early-stage fully remote startup in the best sense of the word. We’re a fun, close-knit team on a mission to automate security and compliance for modern companies and become the European compliance automation leader. We rapidly grew from just three founders to 20 people in less than 2 years after founding.

Your work will significantly impact our tech product used by CTOs, engineering teams, COOs and the whole team will celebrate your wins.

In comparison to many startups we are growing the team at a healthy rate and there is a balance between fast growth and maintaining our runway as we scale. Most of our costs are already covered by revenue.

With new challenges (we're looking to 2x the team next year), you're assured of growth and progress. Our trajectory is fueled by top investors, including Octopus Ventures, Neosfer (Commerzbank), founders of Signavio and many more angels.

Who are we looking for?

We're building an environment at Secfix where ambitious, independent engineers can thrive. We want to grow with people who take pride on building and maintaining actual products, who are curious about how the features we ship are used daily to solve real challenges, and who'll use their in-depth engineering insights to push the envelope on what we can achieve together. We own products and outcomes, not Jira tickets.

Bring your commitment and drive to grow, and we’ll deliver an environment that keeps you happy, healthy, and empowered to do your best work with us.

Scope of this role: 90% backend troubleshooting, 10% new feature development.

Experience that you will ideally bring

• 1+ years of experience in Backend Engineering through first full-time job and internships.
• Solid foundation in object-oriented programming with Java.
• First professional production experience in Java Spring Boot, Hibernate, and SQL.
• Familiarity with 3rd-party APIs and interest in learning monitoring and troubleshooting.
• Willingness to take ownership of tasks, collaborate, and adapt to feedback.

You should apply if:

• You’re ambitious, independent and growth-oriented.
• You bring young talent to our team with at least 1 year of equivalent experience.
• You have strong engineering fundamentals, code efficiently, and you know what you're great at and what you're less great at.
• You thrive when you have autonomy, own as many of the details as possible, and project manage your own work.
• You’re comfortable collaborating and communicating in a remote environment, especially in writing and on video calls. You understand that working remotely doesn't mean working alone. Remember, it requires more pro-active communication than working in the office.

You should not apply if:

• You need a lot of processes to tell you what to do or you're comfortable only picking up highly detailed tickets from a JIRA board
• You only want to write code and don’t really care about the bigger picture and customers
• You don’t want to test, deploy, monitor and troubleshoot your own code
• You don’t want to lead your own projects, but rather be led by someone else
• You don't want to collaborate closely with other areas of the business or engage with users when needed

What happens when you join us?

• You’ll own complex backend issues: Work closely with the Tech Lead to take on challenging backend problems and resolve them autonomously.
• You’ll debug, troubleshoot, and fix bugs: Solve real customer-impacting issues in our production environment, ensuring a smooth experience for our users.
• You’ll strengthen your backend skills: Work with cutting-edge technologies like Java Spring Boot, Hibernate, and SQL, and develop a strong foundation in backend development.
• You’ll collaborate and grow: Work with a talented and supportive team to analyze root causes, design solutions, and improve our backend systems.
• You’ll contribute to new features: Occasionally work on feature development as the team and product expand.
• You’ll live by our values:
  • We are obsessed with our customers.
  • We build smart.
  • We create trust
  • We are hacky.
  • We take ownership.
  • We are leaders of remote

Our Technology Stack

• Backend: Java SpringBoot, Postrgesql, Hibernate
• MDM product: Golang & Osquery
• Infrastructure: AWS with ECS
• Tools: Gitlab CI/CD, Figma, Slack, Notion, Gather.town, ClickUp

Applicants can expect the following:

1. An Introductory call with a member of our talent team ~ 15-20 minutes
2. Take home task (scope: max. 1-2h) and technical interview with Tech Lead
3. Virtual on-site with the team and co-founders on Gather.town (approx. 2 hours)
4. Offer stage

After sending us your application in, please keep an eye out for an email from Grigory (CTO) or Chiara (People Ops). We will respond and move as quickly as possible.

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. In turn, the increase in blood product donations improves a supply level that is at an all time low, and allows for blood-product derived biotherapies to continue to evolve, improve, and save lives for those who face life-threatening conditions (i.e. immune deficiencies and blood disorders). Without an increase in blood product donations, we are facing a worldwide health crisis that ultimately results in rationing of care without the proper resources. Buoy Software is excited to be playing more of a role in improving the state of blood products and blood product donations.We’re working alongside Join Parachute (www.joinparachute.com/) in the opening of small market donation centers across the country that will create local donation center careers, opportunities to donate blood products, and provide financial compensation for those donations that will have a positive economic impact in those communities. The need for blood products is growing rapidly. We want to close the gap in blood product supply and demand by empowering organizations with the right tools. Buoy is the intuitive, data-driven mobile application for donors.About The RoleWe're looking for a Security and Risk Engineer to join our team.

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. Our data stores include MongoDB, PostgreSQL, Elasticsearch, and Redis. The underlying infrastructure runs on AWS using a combination of managed services like EKS, MSK, RDS and ElasticCache and non-managed services running on EC2 instances. We have CI/CD pipelines that build Docker images, run automated tests and deploy to Kubernetes clusters. We also use these images in our local development environment allowing coding locally against all of our services. We have a well-documented public API that is consumed by our front-end JavaScript app as well as numerous integrations. Our infrastructure is heavily automated using Terraform, Ansible and other AWS tools.

Our product development process is inspired by Shape Up. We love open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check out our open source projects like SocketShark, TaskTiger, LimitLion and ciso8601.

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!

• You're interested in getting to know our customers to find the best solution for a given challenge. 
• You code with reason and can justify the important decisions you made during development.
• You can communicate clearly in English, both in writing and verbally.
• You know and can apply best practices when relevant. That means the daily tools of the trade like version control, testing, and refactoring; but also higher level concepts such as good object oriented design.
• You're aware of the trade-offs involved in proper engineering and can make balanced business decisions, keeping in mind all the stakeholders of the project.

If you’re any good at Ruby, this is probably not the first job ad you’ve seen, so we’ve done our best to stand out while also accurately presenting what we’re all about. If it sounds like you would enjoy working with us, don’t hesitate to apply or drop us a line with questions on [email protected].

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.
