Salary

USD 320,000 - 405,000

Requirements

Skills

  • 8+ years in software engineering with 3+ years managing engineering teams
  • Track record of building tooling and processes that enable other teams to succeed without needing detailed technical knowledge
  • Comfort managing a team with a mixed charter of platform ownership, service to other teams, and launch‑driven operations
  • Sufficient technical depth to engage on system design, review pipeline architecture, and debate with senior individual contributors
  • Product mindset and willingness to wear multiple hats when the work calls for it
  • Demonstrated ability to build and maintain peer relationships with partner organizations that have different cultures and incentives
  • Experience recruiting and closing senior individual contributors in a competitive market
  • Prior exposure to LLM evaluation, ML experimentation platforms, or model quality work (even tangentially)
  • Experience with A/B testing infrastructure, feature flagging, or gradual rollout systems
  • Background in developer tools, CI/CD platforms, or testing infrastructure at scale
  • History of managing teams that sit between two larger orgs and making that position an asset
  • Interest in AI safety and alignment (not required but desirable)

Responsibilities

  • Lead and grow a team of prompt engineers and platform software engineers
  • Own the product‑side eval platform, including frameworks, dashboards, bulk runners, and CI integrations used by product teams to measure Claude’s behavior and catch regressions
  • Own system prompt infrastructure for versioning, deployment, rollback, and review tooling across claude.ai, the API, and agentic surfaces
  • Be the steady hand through model launches, acting as the backstop during high‑stakes operational moments
  • Build durable collaboration with other eval groups across the company, owning shared roadmaps and avoiding tragedy‑of‑the‑commons on shared infrastructure
  • Recruit, close, and retain engineers who want to work at the intersection of product engineering and model behavior
  • Shape where the team invests next by sequencing frontier eval development, launch automation, and deeper prompt engineering support
  • Push the team toward measuring hard, high‑impact metrics such as behavioral drift, prompt quality, and harness parity
