About the role

Responsibilities

  • Design platform APIs and shared primitives (not just components) with clear contracts, documentation, and upgrade paths that other teams adopt
  • Profile and instrument real user journeys, then ship the changes that move the numbers
  • Roll out cross-cutting changes safely with codemods, migration paths, and staged rollouts
  • Set technical direction in design and architecture reviews, and document the decisions and operational expectations behind them
  • Work directly with product teams to turn their friction into reusable platform improvements

Requirements

  • Experience shipping and operating user-facing software in production
  • Designed frontend architecture other teams build on (frameworks, state, routing, SSR/CSR, migrations)
  • Built and operated an API/data layer (REST/GraphQL, error handling, caching)
  • Measured and improved client performance with instrumentation and monitoring
  • Made and explained architecture tradeoffs across UX, correctness, delivery speed, and maintainability
  • Comfortable in modern web stacks (TypeScript, React, Next.js, Node.js)
