- Champion technical excellence—coding standards, system design, security, observability and cost awareness—and drive AI integration into engineering practices where it adds value.
- Collaborate cross-functionally with product managers, engineers, tech leads, and other stakeholders to deliver impactful, end-to-end solutions.
- Proactively contribute to team and company initiatives, document decisions, share knowledge, and drive ownership beyond core responsibilities.
