- Drive adoption of AI coding tools across the full SDLC, from planning and design through code review, testing, deployment and setting the bar for how the squad works
- Deliver production grade code across the full stack: Node.js or Python backends, event-driven AWS architecture, and React where the squad needs it
- Mentor and grow engineers across AI and full-stack domains, through code reviews, design documents, and day-to-day pairing
