Job description

Engineering · San Francisco · FullTime · Senior level

The role is about keeping a widely used gateway stable and dependable. A strong candidate has owned reliability for critical production systems, led rewrites or migrations, and can enter an unfamiliar codebase to find the true cause of a problem. Solid Python fundamentals and careful judgment about what a change does to users matter more than a title.

How it fits the AI era

AI tools speed up writing and reviewing code, so the work shifts toward judging which changes are safe and which patterns keep breaking. Reliability still depends on human reasoning about root causes, test trust, and the effect on customers when the gateway fails. The posting expects AI written code to be reviewed as carefully as any other.

How it builds AI experience

This role builds AI experience through the gateway itself, which routes calls across many model providers and tracks spend and access. A candidate can grow by learning how provider integrations fail, how routing and budgets behave under load, and how to test those paths. Rust work during the migration adds another layer of hands on practice.

Worth showing

• Owned production reliability
• Led rewrites or migrations
