Clearmatics is a protocol engineering company. We are building a new financial market architecture that is more open, fair, and resilient than the legacy systems that are in use today. We develop protocols and software that create new markets for risk and more efficient infrastructure for trading, backed by a robust and scalable blockchain network, and secured with modern cryptographic techniques and economic mechanism design.
Clearmatics is based in London but operates on a 'remote first' model. We welcome candidates from all over the world. We have close ties to the Open Source and Ethereum communities, with Vitalik Buterin as an adviser.
The Engineering team at Clearmatics is responsible for developing our blockchain software at Layer 1 and Layer 2. At the core of our stack is the Autonity client, the node software that powers our blockchain network. It is based on Ethereum (go-ethereum) and is secured by Tendermint Proof-of-Stake consensus. Our decentralised platforms are built on smart contracts and decentralised applications, and are supported by backend services in Go.
We're looking to hire a Core Developer to expand our Layer 1 Engineering team.
ABOUT YOU
You're a systems programmer with good knowledge of Layer 1 protocols, and a passion for blockchain and decentralisation. You enjoy working to a high standard and writing code that is clean, performant, and maintainable. You appreciate the importance of careful design choices and can anticipate the impact of code changes on wider system behaviour. You can demonstrate a strong interest in blockchain and may even have open source contributions that you can highlight. You express yourself clearly in writing and in discussions.
RESPONSIBILITIES
You will be involved at all stages of the development lifecycle for the Autonity protocol and its blockchain node client (a fork of go-ethereum). These include: - Implementing new protocol features in Go and Solidity - Developing new distributed systems tests and frameworks - Contributing to protocol and design specifications - Working with members of the community to resolve issues - Your work will ensure that Autonity client is correct, reliable, performant, and secure. This will enable Autonity to serve as the foundational layer for a new ecosystem of decentralised markets.

We're looking for an experienced Backend Go Software Engineer to join the Geckoboard team!
Every single one of us comes to work every day to do something we love. We get to tackle big problems, but in a way that recognises everyone’s need to work with dignity and purpose in a supportive and inclusive environment. It's the most wonderful thing. In fact the fun part is trying to figure out all the different ways we can come up with to make data accessible and understandable for everyone. It really is amazing. The best part is that we work in an atmosphere of openness, trust and transparency, where everyone is empowered to learn and flourish. We're actually doing really well. We have a product our customers love.
We're really excited to be growing.
You'll be joining a team of empowered engineers in a supportive environment that values experimentation, work-life balance and personal development. We've built a culture of knowledge sharing and feedback, so you'll be involved in planning and prioritisation of work as well as peer reviews and pair programming.
We work in small and focused cross-functional teams, usually made up of a Product Manager, a Designer, and a mix of Frontend and Backend Engineers. QA and Infrastructure tend to come in at the points they're needed or for specific projects. We scope out our project such that we're able to deliver meaningful work but small enough to iterate and take on board feedback quickly. We encourage our engineers to get involved in different teams and projects based on their interests, skills and opportunities to learn. We're also equally mindful about technical debt and make sure we dedicate time to addressing it.
At Geckoboard, we are seeking to solve a real problem and build a long-lasting product. As a result, we place a high value on a clean and maintainable codebase, and on practices that ensure we can continue to deliver quality software rapidly and iteratively.

Learning is also a big part of our engineering culture. Once every two weeks every team takes a “Lab Day”, when everyone is free to work on projects that interest them, learn new skills or contribute to open source. We encourage these projects and often they have led to improvements in the way we work or concepts that have then been prioritised, developed further and added to our Product.
Our main frontend application is a large React 16+ codebase and our tests are written with Jest. For communicating with our backend services, we use an Apollo client and query a GraphQL gateway written in Node.js that exposes a single schema but dispatches queries to a number of gRPC services on the backend.
While our backend services are mostly written in Go and run on AWS, the GraphQL gateway is owned by the frontend team, which puts them in the driving seat when it comes to defining the APIs for a new piece of functionality, and provides a single point of reference for both frontend and backend.
While adding features to the product, we’ve been building and maintaining an internal React component library with an emphasis on reusability and documentation. Our frontend team is looking to expand this library, with the potential to open source it in the future.
What we’ve described sounds interesting
You’ve worked with Go before*
You’re interested in distributed systems
You’re collaborative; you empathise, listen and discuss
You actively seek out feedback in your work and to ensure you understand the problem you’re solving
You have experience collaborating on technical decisions in an open and creative environment
You understand the value of automated testing and a test-driven development approach
Right now we're only considering mid to senior-level candidates, if you're interested in joining the Geckoboard team but earlier in your career, head to www.geckoboard.com/careers and get in touch. We'll be hiring at different levels throughout the year, so we'd love to hear from you and chat about future jobs!
At this time, we’re only considering candidates who are (or will be) based in the United Kingdom or Western Europe (CET timezone).
Right now, we work fully remote from around the globe. We’re big on work-life balance and flexible work. We have some core hours but it's up to you to decide how you work around those. We consider 25 days of holiday a year to be a minimum, not a maximum, and have a flexible working policy so that if you need to step out for a school run, an appointment, or something else, it’s no problem. We don't do "crunch time" and have a deep commitment to a clear separation of life and work.
Some of our team also have shorter working weeks and we’re more than happy to accommodate this or other arrangements when possible. Learn more about life at Geckoboard at www.geckoboard.com/careers.
The whole process takes about 3 weeks end to end, but we’re flexible!
