  • Support the lead architect in transitioning early prototypes into a fully automated, production-ready system
  • 3+ years of software development experience
  • Experience with Rust, focusing on async runtimes (Tokio), concurrency, and memory-efficient
  • Experience with Web3, Blockchain, and decentralized trading infrastructure
  • Proficiency with low-latency systems (networking, API integration, and high-frequency execution patterns)
  • Ability to work with arbitrage mechanics, including spread capture, race conditions, and cross-platform inefficiencies
  • Deep knowledge of execution complexity in fast-moving environments with real-time pricing dynamics
  • Strong communication skills in both spoken and written English
