Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the Role We're looking for a Staff Software Engineer to set technical direction at the intersection of engineering and research on the Claude Code team.

What you'll do
- Set technical direction for evaluation systems, research infrastructure, and internal tooling across the Claude Code team
- Architect eval frameworks that measure model capabilities across diverse coding tasks and scale with our research roadmap
- Lead the design of infrastructure that enables researchers to run experiments at scale, and make the foundational tradeoffs that shape how the team operates for years
- Identify the highest-leverage engineering investments—often before anyone has asked for them—and drive them to completion
- Serve as a senior technical bridge between product and research, using strong product intuition to influence which capabilities we prioritize and how we measure progress against them
- Mentor and raise the bar for other engineers on the team; review designs, unblock peers, and model the engineering standards we want to scale
- Partner with research leads to translate ambiguous research questions into durable engineering solutions
- Own critical systems end-to-end, from architecture through production reliability, and take responsibility for their long-term health
