Job description

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.

Requirements

  • 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.
