  • Support hiring and mentoring future engineers
  • Establish engineering best practices and technical standards

Requirements:
  • 5+ years of experience with Next.js (App Router), TypeScript, React, and Postgres/Supabase.
  • Proven experience shipping products end-to-end as an owner or key contributor.
  • Strong fullstack capabilities (frontend, backend, database, APIs).
  • Experience owning infrastructure and system reliability.
  • Solid understanding of security fundamentals (auth, data protection, etc.).
