About CoW DAO

CoW DAO is on a mission to build the most robust, user-protective, and efficient trading infrastructure in DeFi. CoW DAO is the creator behind CoW Protocol (the engine behind CoW Swap). Operating as a dominant player in DeFi, CoW Protocol recently crossed a massive milestone of over $200 Billion in lifetime trading volume and consistently ranks as a top-two DEX aggregator by market share.

Through combinatorial batch auctions, a competitive network of "solvers," and a unique Coincidence of Wants (CoW) matching engine, CoW Protocol protects traders from MEV bots and secures the absolute best execution prices on the market.

About the Role

Location: Fully remote team, and although hiring is almost global, there is a preference for this role to be based in Europe or remote +/- 4 hours CEST time.

Not hiring from the US, Australia, or New Zealand.

Position: Full-time contractor

CoW DAO is looking for an enthusiastic, motivated Staff Backend Engineer to help build the next generation of decentralised trading protocols. As a dedicated backend engineer, the candidate will gain ownership of existing backend services and influence the creation, design, and execution of future features and products. The engineer will work on technically challenging aspects of off-chain services and developer-facing APIs and help ensure the delivery of reliable and performant features to improve CoW Protocol.

Tech Stack

Backend Code: Rust, Tokio, Cargo, Git (https://github.com/cowprotocol/services)
Infrastructure: Pulumi, AWS, Docker, Kubernetes, Grafana, Prometheus, Elasticsearch
Other codebases: Typescript, Python, Solidity

What You Will Do

Architect and design off-chain services (core auction protocol as well as the orderbook) to support feature growth and the rapidly changing requirements that come from being an application on a constantly evolving blockchain.
While the focus will be writing concurrent backend systems in Rust, the engineer will also interact with Smart Contracts written in Solidity and develop an understanding of auction mechanisms and DeFi protocols.
Participate in the on-call rotation to help ensure the reliability of production systems (on-call work is additionally compensated).
Work closely with researchers and the product team to ship features and come up with new solutions for challenging technical problems.
Deliver high-quality code for features from concept until production (including state-of-the-art monitoring of production systems).
Give thoughtful and in-depth code reviews of colleagues’ contributions to the open-source codebase.

Who You Are

You have 8+ years of production experience with systems-level programming languages, with at least 3+ years of hands-on production experience using Rust.
You have practical experience working in web3 (ideally in DeFi and the Ethereum ecosystem).
You have excellent computer science, programming, and algorithmic skills.
Experience with operating, maintaining, and architecting complex software systems.
You care deeply about the quality, readability, observability, and testability of your code.
You proactively give technical direction to improve performance, prevent issues, optimise data usage, and refactor the codebase.
You are a team player, strong communicator, and gladly share your expertise with others.
You collaborate effectively with a remote-first team on a large, open-source codebase.
Ideally, someone senior who can mentor colleagues and provide direction.
You are excited to explore and gain experience with Ethereum.
