• Review AI-generated code critically for correctness, quality, and production safety


• Deliver changes to staging and validate them through integration and end-to-end testing

Requirements




About You

• Senior-level experience building backend, platform, automation, or internal tooling


• A software-first mindset and comfort working in operationally complex domains


• Strong technical judgment, especially when reviewing AI-generated output


• Experience turning ambiguous problems into structured investigations and executable plans


• Strong knowledge of AWS infrastructure and cloud services


• Working knowledge of Python and TypeScript, so you can review and guide implementation
