• The Full-Stack Product Engineer takes agent capability and turns it into product. • End-to-end feature delivery across the surfaces engineers actually use to do their work — code understanding, code translation, modernization authoring. • Pairs tightly with the Principal Designer in code: Designer absorbs visual-heavy surfaces, the Full-Stack Engineer owns logic-heavy surfaces (authoring, review, agent integration). • Write specs, ship, watch usage, iterate; close the loop from design through deploy. • Push back on a spec you think is wrong before writing the code. • Own the product-quality bar across the surfaces you ship — performance, accessibility, polish, and the moment-to-moment feel. • Integrate agent output into product surfaces in a way that respects both engineering correctness and user trust.
