Your role and mission
You will design, build, and scale significant systems and features, owning them end-to-end. You will take on ambiguous, higher-scope problems, make the key technical tradeoffs, and be accountable for the correctness, performance, and reliability of what you own.

- Partner across product, design, and engineering to solve problems that span teams
- Raise the quality bar and set patterns that make the people around you more effective
How we work: AI-native by default
You treat AI-assisted development as a core part of how you work. You use agents to move faster on design, investigation, and implementation, with clear judgment about where to review closely, and you look for ways AI raises the leverage of the whole team.
What we are looking for
- A strong track record of owning and shipping systems at scale
- Command of system design, data modeling, and the reliability and cost tradeoffs that come with scale
- The ability to lead ambiguous work to a clear outcome
- Genuine, current fluency with AI-assisted development
- A high bar for quality and a strong sense of ownership
