• Deep understanding of decentralized exchanges and the current DeFi landscape
• Experience building and maintaining public APIs

• Ability to run and maintain systems on cloud infrastructure
• Based in London or working remotely from anywhere in Europe

Nice to have:

• On-chain trading or strategy development experience
• Familiarity with ecosystems such as Solana, Sui, or Cosmos
• Experience diagnosing performance, latency, or throughput issues
• Interest in product design and user experience alongside engineering
