  • Oversee security, compliance infrastructure, and regulatory readiness (SOC 2, etc.)
  • Define and own the protocol/smart contract strategy if applicable

Requirements

  • 8+ years in software engineering, including 3+ years in a technical leadership role
  • Deep expertise in at least one of: fintech infrastructure (payments, lending, banking-as-a-service), blockchain/smart contract development (Solidity, Rust/Anchor), or security-first distributed systems
  • Experience taking a product from 0 to production in a startup environment
  • Track record of hiring and retaining strong engineers
  • Strong communication — you can explain architecture to investors and code to engineers
