About the Job

Requirements

  • 4–7 years of software engineering experience with strong fundamentals across backend and infrastructure.
  • A demonstrated track record building and scaling production systems.
  • Comfort working in early-stage ambiguity and defining problems, not only solving them.
  • Fluency with modern artificial intelligence development tools such as Claude, Cursor, and Codex alongside traditional engineering practices.
  • A high-ownership mindset and a bias toward shipping.

Responsibilities

  • Architect and build scalable backend and infrastructure systems that power the core product.
  • Work across the full stack as needed, owning problems end-to-end rather than handing them off at boundaries.
  • Establish engineering standards, tooling, and practices that will scale with the team.
  • Collaborate closely with founders on product direction and technical trade-offs.
  • Leverage modern artificial intelligence coding tools to move faster and build more.

Desired Qualifications

  • Prior startup experience or experience at a high-growth engineering organization, such as a hyperscaler or company with a strong engineering culture.
