Key Responsibilities
- Technical Direction & Architecture: Define backend architectural patterns and engineering standards (API design, data modeling, testing). Drive solution design for complex features while balancing velocity with long-term maintainability.
- Hands-on Engineering: Write clean, testable code for core platform foundations and critical migrations. Conduct deep, fast code reviews across sub-squads.
- AI-First Engineering: Champion AI-assisted development (code generation, testing, automated reviews) and collaborate on integrating practical AI features directly into workflows.
- Mentorship & Growth: Coach engineers through technical discussions, design reviews, and pairing. Conduct technical assessments and interviews to raise hiring standards.
- Cross-functional Collaboration: Serve as the technical voice in product discovery alongside PMs, BAs, QA, and Design to shape scalable user-facing features.
