Lab49 has an opportunity available for a Go Engineer to lead work on complex and challenging projects to drive transformative change for our top- tier Financial Services clients. Operating in an Agile environment, the Go Engineer will have strong experience to work on next-generation financial systems.
Requirements:
WHO ARE WE?
Lab49 is a specialist consultancy that designs and develops bespoke and innovative technology solutions in partnership with key participants in financial markets. We enable our clients to meaningfully differentiate themselves and successfully navigate the shifting landscape in financial services. Our specialist focus on financial markets and our integrated strategy, design and product development expertise uniquely position us as a partner capable of effectively delivering and embedding best-in-class solutions tailored to meet clients’ complex and varied commercial and technical needs.
We were founded in 2002 to bring Silicon Valley solutions to Wall Street’s door. Since then, we have worked on successive waves of technological change, including distributed computing, high-speed automation, enterprise UX and digital distribution (for which Lab49 was among the first significant practices established on Wall Street), DevOps, cloud and data science. Today, we are an established partner in financial markets, having delivered hundreds of projects for clients including all of the world’s tier-one investment banks and many of the largest buy-side firms globally.
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.
