What you will do

• Own reproduction logic, guardrails, and checks that prevent unsafe pull requests from reaching customer repositories.

• Make architectural decisions covering schema design, service boundaries, and speed-versus-correctness tradeoffs.
• Define testing standards, on-call practices, and release criteria.
• Work across detection quality, high-volume ingest pipelines, and the customer-facing review UI.

• 3+ years of experience shipping production software, with the ability to work beyond a core specialty.
• Strong TypeScript proficiency across frontend and core services.

• Experience designing and operating cost-aware, high-volume data pipelines and event-processing systems.
• Experience making long-term architectural decisions, including schema design and service boundaries.
• Strong product sense and ability to solve ambiguous problems independently.

Nice to have

• Experience with pull request review automation or code quality tooling.
• Experience with production observability and monitoring systems.
