* Build and review production PRs, identifying architectural, security, performance, and maintainability issues in both human and AI-generated code
* Apply modern AI engineering practices (e.g., specs, coding agents, AI editors, structured implementation, and review workflows) to increase development velocity
* Own complex and ambiguous engineering problems from requirements through production
* Work directly with customers, product managers, engineers, and external partners to translate requirements into technical solutions
* 6+ years of back-end development experience
