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.
