We are looking for an enthusiastic, self-motivated backend engineer to help us build the next generation of decentralized trading protocols. As a dedicated backend engineer, you will gain ownership of our existing backend services and influence the creation, design, and execution of future features and products. You will work on technically challenging aspects of our off-chain services and our developer-facing APIs and help ensure the delivery of reliable and performant features to improve CoW Protocol.
What you will do
Develop new functionality for both our off-chain services (optimizing transaction execution, scaling order throughput, increasing protocol decentralization) as well as our APIs (price estimation & order placement, real-time blockchain state monitoring, server-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 DeFi protocols
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 our production systems)
Help our engineering team maintain and improve the reliability of the existing features and join in the on-call rotation
Give thoughtful and in-depth code reviews of your colleagues' contributions to our open-source codebase
Backend Code: Rust, Tokio, Cargo, Git ( https://github.com/cowprotocol/services )

CoW Protocol is on a mission to create the fairest and most efficient venue for exchanging digital assets on all EVM-compatible chains. Since launching 2 and a half years ago, we have passed more than $26bn (yes, billion) in trade volume and become the 2nd most popular DEX Aggregator on the market -- aiming for #1. We are an ambitious, fast-growing, and international team working at the forefront of DeFi. We believe that we can make markets both more efficient and fair by building the ultimate batch auction settlement layer across EVM-compatible blockchains. CoW Protocol is the industry leader in protecting users from MEV, including frontrunning and sandwich attacks, which lose traders thousands of dollars every day. The protocol does this by matching trades peer-to-peer and leveraging batch auctions to circumvent MEV bots. By joining us at this early stage, you will make fundamental decisions that will shape the course of the CoW Protocol.
