  • Own contract-to-product integrations end to end.
  • Improve deployment safety, environment management, and operational readiness in production.
  • Help shape architecture across core protocol, indexing, APIs, and operator tooling.

Requirements

  • 5+ years of software engineering experience.
  • Strong Solidity and Foundry experience.
  • Proven experience building or maintaining DeFi vault systems.
  • Strong React and Next.js experience.
  • Experience shipping and operating applications on Vercel.
