About the Role

A Y Combinator-backed AI startup is looking for a Founding Engineer - Full Stack to join a small founding team at the ground floor.

What We're Looking For

Required
  • 1+ years of experience on engineering teams (2+ preferred), including at least one stint longer than 18 months in a strong startup or scale-up environment.
  • Full-stack proficiency - comfortable owning customer-facing UI through to infrastructure.
  • Hands-on experience with React, Python, Terraform, and AWS .
  • Experience building agentic systems or working with LLMs in production.
  • Strong product sense and design instincts; able to translate customer needs into shippable features.
  • Startup experience or self-driven personal projects that demonstrate initiative and high agency.
  • Must be a US citizen or have US work authorization (no visa sponsorship for candidates outside the US).
Nice to Have
  • Scientific or academic research background.
  • Direct customer-facing experience in a technical role.
  • Enthusiasm for adopting AI-powered coding and productivity tools.
Compensation & Benefits
  • Salary: $150,000 - $250,000 USD annually (depending on experience)
  • Early-stage equity
  • Visa sponsorship available for eligible candidates
