# Introduction

We are a SaaS ticketing platform that is very excited about the future. Coming out of the pandemic, we completed an exciting evolution of our platform. This involved moving from a traditional RoR architecture to a modern "single page application" (SPA), exposing our application as a set of APIs consumed by Ember to provide a rich interactive experience.

Completing this work has allowed us to focus on new feature development. We have already seen the benefits of the new platform in terms of productivity and speed of rolling out new features.

We want to expand our backend team with new people to cover Ruby and Ruby on Rails server development to accelerate this potential and deliver an ambitious product roadmap. In terms of experience, we are looking for experienced developers who are comfortable working with a large codebase and a complex domain.

The work will be a mixture of new feature development exposed as APIs for the front-end development team and infrastructure-focused improvements on our backend.

The feature areas we focus on are significant enhancements to our CRM functionality, improvements to our public API and investment in Business Intelligence and Analytics. 

This year, a specific focus will be on building out our data and analytic capabilities using a combination of Snowflake at the data layer and Sigma for visualisation. This work will then provide a platform for integrating AI capabilities into our platform.

# Skills & Requirements

- 4+ years experience developing web applications

- Experience with programming Ruby/Rails required with the role focused on server development

- Understanding of front-end technologies: JavaScript, HTML, CSS, and JS frameworks like React/Ember are welcomed but not required

- Experience with Chef and Terraform a bonus

- Strong programming skills with a focus on clean design, well-refactored code and automated testing

- Experience with Business Intelligence and Analytics is also welcomed but  not required

- Comfortable working as part of a fully remote dev team.

# Technologies we use

- Ruby on Rails is our primary server framework evolving towards pure API server

- EmberJs is our primary front-end development framework

- JSONAPI::Resources, http://jsonapi-resources.com/, is how we are building our APIs

- MySQL / Redis are our primary storage engines

- Snowflake / Sigma are our chosen data, analytics and AI-enabling technologies

- All our servers are Ubuntu based managed through CHEF

- Deployed on AWS using Terraform for managing infrastructure

- GitHub for source code management and process support

- GitHub actions for continuous integration

# How we work

We run a lightweight process that focuses on feature-based weekly delivery. Our coordination and communication are mostly through daily 'catch-up meetings' and appropriate tools such as Linear for backlog management, Slack for communication and Git(GitHub) for source control and feature deployment through PRs and Milestones.

From a coding perspective, we strongly emphasise clean, minimal, well-refactored code backed up by a robust suite of automated tests. In addition, we use peer review for all design and development work.

In general, we strive for an approach that empowers and trusts iniduals to 'do the right thing'; as a team, we try to keep each other true to this.

# 100% Remote working

Our development team works remotely with members in Austria, Germany, Portugal, Sweden, South Africa, Ireland and the United Kingdom. Our wider organisation has people based in the United Kingdom and Ireland. Dublin is our headquarters and main office - with the core Support and Sales and Marketing teams.

Remote working has been part of our company's DNA since our founding. It offers many advantages to both Ticketsolve and its employees. This culture means you should be comfortable working as part of a fully remote team.

Important to note that time zones are a consideration for us with remote working. Our experience is that European, some Asian and East Latin American time zones are preferable, allowing for collaboration at reasonable times.

# Recruitment process

We are initially looking for resumes and portfolio examples of your work, e.g., GitHub repositories, blog articles, etc. If you do not have anything suitable, don't worry. As part of the process, we will introduce some coding tasks, e.g., code reviews, whiteboard design sessions, and pair programming.

From there, we filter down and do a series of remote interviews. We start with an introduction call to explain the project and answer questions. From there, we will have a mixture of technical and culture-fit calls. 

After this stage, we will be in a position to make a formal offer.

Please submit resumes to **[email protected]** with the subject **"Job Application"**. Please note that we will not respond to all applications due to the volume of applications; instead, we will make contact when there is a potential fit.

About Us

Chorus One is one of the leading operators of infrastructure for Proof-of-Stake networks and decentralized protocols. Tens of thousands of retail customers and institutions are staking billions in assets through our infrastructure helping to secure protocols and earn rewards. Our mission is to increase freedom and speed of innovation through decentralized technologies.

We are a erse team of 70+ people distributed all over the globe. We value radical transparency, striving for excellence and improvement while treating each other with kindness and generosity. If this sounds like you, we’d love to hear from you.

Position Overview:

As a senior software engineer, you will join one of our engineering teams to assist in building and maintaining tools and automation to support our validator operations. We take the upstream node software from projects like Ethereum, Solana, Cosmos, or Avalanche; compile it; run it on one of our servers; and then make sure it is reliable and secure, monitor it, and keep it up to date. We do this for more than 60 blockchain networks, which means that it is not feasible to do all of this by hand. Instead, we build automation. Some of the things we do:

• Contribute to upstream software to improve observability, and build monitoring tools from scratch where none exist. The teams that build the node software are not the teams that operate this software at scale, and as such, observability is often not a first priority. We develop our own tools for on-chain and off-chain monitoring, both for short-term metrics (to alert on) and long-term metrics to measure our performance, and to support optimisation decisions.
• Build tools to track and manage our fleet of servers. We work mostly with bare-metal servers across multiple providers. This means that no vendor-specific portal is going to give us a complete overview of our infrastructure, instead we have an in-house tool that integrates with vendor APIs and gives us a central overview.
• Automate machine provisioning. Instead of working with 10+ cloud and bare metal providers’ flavor of installing Ubuntu, we build our own installer that is uniform across our infrastructure.
• Track and automate builds. Each of the 60+ networks we operate regularly releases updates. It would be tedious to manually git pull && make for every release, instead we have automation watching for new releases that automatically builds them and registers them in our package registry.
• Automate updates and failover. When we have a new package, we still need to roll it out to our fleet and restart any nodes, in a controlled manner and without downtime. For validating nodes, we also need to fail over before we restart them, and confirm the new node is healthy. To automate this, we need to have 100% confidence in our tooling, because a mistake here can lead to double-signing, which incurs a financial penalty.
• Automate snapshot creation and storage. Blockchains node software is stateful in nature: the chains are often terabytes in size. While it is possible for new nodes to sync from the p2p network, this can take days to weeks, which means it is not a suitable method when we move workloads between machines. We automate taking snapshots of this data, so we can be more flexible about what runs where, without compromising on security.

Our internal tooling:

It is written in a mix of Rust, Python, Go, and a bit of TypeScript. We use Postgres as our database of choice. We deploy our code either directly onto Ubuntu hosts, running under systemd or in Docker containers, and we also have a Kubernetes cluster running various stateless applications. Due to the erse nature of the software we run, we also have to occasionally e into codebases written in C, C++, OCaml, or TypeScript.

You can learn more about our approach to operating nodes in our Network Handbook.

Key Responsibilities

• Design and develop new features. Discuss with internal stakeholders to clarify how our next feature should look, discuss with fellow engineers how it should be implemented, and then drive implementation to completion.
• Support and collaborate. Review and discuss engineering designs, review code, help fellow engineers, and mentor them on a technical level.
• Innovation and continuous improvement. Seek to simplify, optimize, and secure our staking services and systems.
• Take part in on-call rotation approximately 2 days per month. You will be responsible for automation that manages our validators and infrastructure, including its uptime and incident response.

Job requirements

What we are looking for:

• 5+ years experience as a Software Engineer.
• Experience with operating and maintaining server-side software in production.
• Deep understanding of at least one compiled statically typed programming language such as Rust, Go, Kotlin, C++, or Haskell.
• Experience with at least one scripting language such as Python.
• Experience using SQL databases, preferably PostgreSQL.
• Strong communication skills and ownership to drive new features independently.
• Interest in blockchain technology, in particular distributed systems and consensus algorithms.
• Affinity with infrastructure and the lower levels of Linux userspace.
• You are able to work in the following time zone: Switzerland ± 6 hours.

What We Offer:

🌱 Growth & Learning

We’re committed to your development! Benefit from an annual 3,000 CHF learning budget that goes beyond just conferences—supporting your physical, emotional, and mental well-being too. Attend up to two conferences a year to e deeper into the Web3 space and connect with the community.

Fully Remote | Part Time | Equity Based

**Roles and Responsibilities:

The Backend Engineering Consultant will take requirements directly from the CTO, and independently design and develop robust, production grade solutions. This is an inidual contributor role. The Engineer will be focused exclusively on design and development, not mentorship, cross training or management. Primary responsibilities include:

**Develop Microservices using Python

Our primary language is Python, and our API framework is FastAPI. The Engineer will spend much of their time designing, developing and extending Python modules to power the core logic of our graph.

**Create and Deploy Containers using Docker and GH Actions

We take a container-first approach, leveraging Docker to encapsulate our products for deployment to cloud infrastructure. We use GitHub Actions for CI/CD to target infrastructure such as ECR. The Engineer will create Dockerfiles and GH workflow files to define the necessary environment for each application and deploy it.

**Create Infrastructure Across Cloud Providers using IaC

Our product is intended to be used across all major cloud providers, e.g. AWS, GCP, Azure. As such, we leverage Terraform to declaratively define services across providers. You will create Terraform scripts which are capable of creating and manipulating infrastructure with complex configurations, across providers.

**

**Education and Relevant Experience

M.S. or B.S. in a S.T.E.M. or quantitative field is highly preferred, however, it is not required. Relevant experience with proven contributions is the highest indicator of potential for success in our opinion. We’ll look for 10+ years in a range of job titles or roles that overlap with the Roles and Responsibilities section. A clean GitHub demonstrating related skills is most important. However, we understand that many professionals don’t have time to create or contribute to public facing repositories, so we encourage applications from Engineers without a robust portfolio.

**Deliverable, Cost and Quality Mindset

danzek.ai™ is a startup, as such, we must be extremely focused on balancing time, cost and quality. The Engineer will need to select libraries and services that are cheap, yet effective. The Engineer will also need to design solutions which are extensible and carefully selected regarding scope. Lastly, the Engineer will be expected to mitigate tech debt at all costs by focusing on best practices, modern patterns and careful implementation.

**Trust and Integrity

As a startup, our IP is extremely valuable. We expect the Engineer to keep our code and designs secret, treating them with the utmost care from an InfoSec perspective. We’re offering the Engineer equity, as such, they have a tangible interest in protecting their ownership.

**Flexibility

As a consultant, the Engineer may work on days and times that are most convenient for them, and performance will be based upon contributions, not hours worked. We also don’t measure performance in KPIs such as a SLOC, which are often decoupled from quality and tangible benefits.

**What you will be doing

Our Circuit Marketing Sites (CMS) team plays a crucial role in showcasing our products to the world. But right now, our marketing site isn’t keeping pace with our product innovations, and we’re looking for an experienced engineer to help us change that.

You’ll be responsible for owning entire pages and sections and translating design concepts into performant, SEO-friendly, and visually stunning experiences. There are no hard deadlines, no micro-management, and no layers of approvals—just the freedom to build high-quality web experiences at your own pace.

Once our core site is up to speed, you’ll have the opportunity to build mini-apps and interactive tools that capture attention, drive traffic, and generate leads. We love experimenting with creative ideas and pushing the boundaries of what’s possible.

Your typical day-to-day:

• Building high-performance marketing pages from Figma designs using Next.js, React and Tailwind.
• Owning projects from start to finish, ensuring a seamless blend of performance, aesthetics, and SEO best practices.
• Collaborating with our marketing design team to bring interactive and engaging web experiences to life.

• Staying ahead of the curve by leveraging the latest web innovations (React 19, Next.js 15, etc.).
• Conducting code reviews and ensuring the highest level of quality in your work.

What you won’t be doing

• Having lots of meetings. Expect ~one meeting per week. If you rely on frequent check-ins to stay on track, we’re not the right fit.
• Working to unrealistic deadlines. We optimize for quality and long-term progress, not burnout!
• Managing people. While you’ll share knowledge and manage your own projects, this is a hands-on inidual contributor role.

We’d love to hear from you if you:

• Have 6+ years of experience in frontend development, with strong expertise in React, TypeScript, and modern full-stack meta-frameworks (e.g., Next.js, Astro, Remix, or similar).
• Like building fast, SEO-optimized, and visually stunning marketing websites.
• Understand performance optimization techniques, including server-side rendering (SSR) and static site generation (SSG).
• Are experienced working on public-facing marketing sites with a focus on performance.
• Work well independently and can figure things out, even when requirements change.
• Communicate clearly and enjoy working with designers to build the best websites possible.
• Can spot a simpler way to do something and aren’t afraid to suggest it!
• Are based in UTC-5 to UTC+2 time zones
• Can speak and write in English at a professional level.

It would be nice if you have:

• An eye for UI/UX and animations, with experience bringing designs to life.
• Familiarity with Sanity.io.
• Experience with Next.js
• Accessibility experience

**Who we are, what we do, and how it’s going

Back in 2017, we saw an issue with last-mile delivery - it was too complicated and stressful for drivers. Circuit started a mission to change that by choosing to develop an app that put the driver, and their customers, first.

We were astounded by the response we received. Within our first year, we had almost 1,000 customers, $100k in ARR, and a team consisting of our two co-founders, Jack and Pol. With a lean team of ~40, we’ve grown to $25M ARR, helping over 100,000 drivers deliver more than 1 billion packages worldwide—about 20 every second!

Our Hiring Process

Our hiring process for this role has five stages (if we include the 10-minute application!) and usually takes ~three weeks for the whole process. At every step, you will be able to ask questions of your own and make sure that we are the right choice for you.
