📋 Description

• Own the end-to-end product quality of every user-facing application the AI Platform ships • Build the frontend architecture and the shared design system / component library used across every AI Platform application • Ensure RBAC-aware interfaces, making sure program teams, governance stakeholders, leadership, and platform engineers see the right data and controls • Lead the backend-for-frontend layer, API patterns, data contracts with MLOps, and the seams where the UI meets the platform • Define the application-level testing strategy: unit, integration, and end-to-end suites • Instrument every application for adoption, feature engagement, error rates, and load times, and surface insights that inform the platform roadmap • Optimize frontend performance, including bundle optimization and lazy loading • Define and enforce UX quality gates that no application ships below • Collaborate with application teams to build user-facing applications alongside MLOps engineers • Wire telemetry into every surface and read the generated data for informed decision making

🎯 Requirements

• 5+ years of full stack engineering experience shipping production web applications, including at least 2 years where you were the senior frontend voice on a team or product • Deep proficiency in modern React (hooks, context, suspense, performance patterns) and the surrounding ecosystem • Hands-on experience designing or substantially evolving a shared component library or design system used by more than one application • Strong fluency in Python and FastAPI (or comparable Python web framework experience) for backend-for-frontend work • Demonstrated ownership of accessibility (WCAG 2.1 AA) as a first-class engineering concern, not a final-week checklist • Experience implementing role-based access controls and permission-aware views in real applications • A real testing practice: unit, integration, and E2E with one of Playwright or Cypress • Experience instrumenting applications with usage telemetry and using that data to inform product decisions • Strong written communication — you will write technical specs, design system documentation, and API contracts that other engineers rely on • Bachelor's degree in Computer Science, a related technical field, or equivalent professional experience

🏖️ Benefits

• Healthcare benefits for full time and part time positions from day one, including vision, dental and benefits for domestic partners • Atmosphere of collaboration, cooperation and collegiality
