We're looking for a deeply experienced Senior Frontend Engineer to raise the bar for frontend architecture and quality in our AI team, align it with the broader application best practices, and help promote frontend excellence across teams. This is not a feature factory role. This is a high ownership, cross team leadership role. Own frontend architecture and quality for all AI features. Align AI frontend implementation with wider application standards, including shared components, service API patterns, and design system usage. Partner with organization frontend leaders to learn, internalize, and propagate best practices across teams. Contribute to and evolve our shared design system and atomic component architecture. Drive consistency across shared components, service APIs, and UI patterns. Lead large, complex frontend initiatives end to end. Work closely with Product and Design to translate ambiguous ideas into scalable, high quality UI systems. Provide strong technical direction and mentorship to frontend contributors. Establish frontend observability and tracking standards, including analytics and instrumentation. Ensure performance, accessibility, and maintainability across the UI surface area. Collaborate with backend and ML engineers to integrate AI powered experiences into a production grade frontend.
