CoW Protocol is looking to hire a Senior Backend Engineer to join the team.
About CoW DAO
CowDAO is an open organization of developers, traders, market makers and many more community members aligned with its vision. CowDAO is focused on fair and decentralized trading systems - in particular, building, maintaining and advancing the Cow Protocol. Cow Protocol technology powers a network of traders and solvers, enabling trustless and efficient peer-to-peer trading. Leveraging batch auctions as a key concept uniquely positions Cow Protocol as native trading infrastructure for discrete-time settlement layers like Ethereum and enables fair and accessible trading to its users.
CoW Protocol is on a mission to create the most fair and efficient venue for exchanging assets on all EVM compatible chains. Since launching a year ago, we have passed $12bn (yes, billion) in trade volume, and become the 4th most popular DEX Aggregator on the market -- now we're aiming for #1. If you are a high-performing team player who wants to work on some of the most-important problems in Ethereum (MEV protection, batch auctions, and more), we want to talk to you!
About the role
We are looking for an enthusiastic, self-motivated backend engineer to help us build the next generation of decentralised trading protocols. As a dedicated systems engineer, you will gain ownership of our existing backend services, as well as have the ability to influence the creation, design, and execution of future features and products. You will work on technically challenging aspects of our off-chain services as well as our developer-facing APIs and make sure we deliver reliable and performant features to improve the core CoW protocol.
You will have the opportunity to work with us on this challenge in one of our existing co-working spaces in Berlin or Lisbon. Alternatively, you can join us as a remote employee and work from your hometown, where we can also provide a membership for a local coworking space.
What you will do
- Develop new functionality for both our off-chain services (optimising transaction execution, scaling order throughput, increase protocol decentralisation) as well as our APIs (price estimation & order placement, real-time blockchain state monitoring, client communication channels)
- While your focus will be writing concurrent backend systems in Rust, you will also interact with our Smart Contracts written in Solidity and develop your understanding of auction mechanisms and Decentralized Finance.
- Work closely with researchers and product managers to ship features and come up with new solutions for challenging technological problems
- Deliver high quality code for features from concept until production (including state of the art monitoring of our production systems)
- Give thoughtful and in-depth code reviews of your colleagues’ contributions to our open source codebase
Our Tech Stack
Product Code: Rust, Tokio, Cargo, Git
Deployment: Docker, Kubernetes, Grafana, Prometheus, Kibana
Who you are
- You have 3+ years of experience with distributed systems engineering, preferably in Rust (Go, C++, Java or similar)
- You have excellent computer science, programming and algorithmic skills
- You care deeply about the quality and readability of your code
- You proactively giving technical direction such as improving performance, preventing issues, data usage, refactoring the codebase
- You are a team player, strong communicator and love to share your knowledge with others
- You collaborate effectively with a remote-first team on a large, open source codebase
It’s a plus if you bring:
- Understanding of the Ethereum blockchain and ecosystem, general finance and/or game theory and mechanism design.
- Experience with architecting complex software systems
