Senior Software Engineer (Top Crypto Trading Firm)
Backend Engineer (Rust / Python – DeFi Trading)
London or Remote (Europe)
A DeFi-native trading platform is building high-performance, user-focused trading tools and is looking for a backend engineer to help shape the core platform. The team strongly believes DeFi is the future of finance and is focused on making fast, reliable on-chain trading accessible to everyone.
You'll work hands-on with Rust and Python, build public APIs, and integrate directly with smart contracts and trading logic. This is a highly product-driven role with real ownership and daily production impact.
What they're looking for
- Strong experience with Rust and/or Python
- Hands-on experience working with EVM smart contracts (application-level Solidity, not just theory)
- 3–4+ years in crypto / DeFi–native roles
- Solid understanding of decentralised exchanges and the current DeFi landscape
- A grasp of trading concepts, or a strong desire to move deeper into trading systems
- Experience running production systems in the cloud
Nice to have
- Writing and deploying smart contracts
- Experience diagnosing performance or latency issues
- On-chain trading experience or strategy work
- Exposure to other ecosystems such as Solana, Sui, or Cosmos
A strong opportunity for someone who is deep in crypto, cares about the product as much as the code, and wants to help build the next generation of DeFi trading tools.
