Responsibilities
- Build and maintain the web frontend for Apple’s large-scale data annotation and quality platform.
- Design React component architectures using hooks, state management, and rendering optimization.
- Improve frontend performance through bundle optimization, lazy loading, profiling, and sound architectural decisions.
- Design or contribute to asynchronous data patterns, including REST and GraphQL APIs, WebSockets, SSE, and backend-for-frontend layers.
- Develop interfaces for streaming model outputs, long-running asynchronous tasks, and event-driven state.
- Partner with product design to shape interaction patterns, implement high-fidelity interfaces, and contribute to design systems and component libraries.
- Lead frontend workstreams across interdisciplinary projects involving design, backend, product management, ML, and multiple engineers.
- Build and maintain quality through unit, integration, and end-to-end testing, accessibility practices, and frontend security hygiene.
Requirements
- Master’s degree in Computer Science, HCI, or a related field.
- Proven professional frontend engineering experience with deep expertise in React and the modern JavaScript/TypeScript ecosystem.
- Strong command of React architecture, including component design, hooks, state management, rendering optimization, and production frontend performance.
- Solid understanding of asynchronous data patterns and experience with REST or GraphQL API design, WebSockets or SSE, and backend-for-frontend layers.
- Experience with unit, integration, and end-to-end testing and grounding in web accessibility and frontend security best practices.
- Ability to engage with product design early, provide constructive input, and implement pixel-perfect interfaces from high-fidelity specifications.
- Experience contributing to design systems or component libraries used across multiple teams.
- Experience leading frontend workstreams in cross-functional or interdisciplinary settings.
- Experience with annotation, task-editor, review-tool, or other complex data-dense productivity interfaces is preferred.
- Experience with agentic UI patterns and integrating LLM or agent backends into production web frontends is preferred.
- Strong proficiency with AI-assisted and agentic coding tools such as Claude Code, GitHub Copilot, or Cursor, with sound judgment when reviewing generated code.
- Familiarity with Vite, webpack, Vitest, Jest, Playwright, and Node.js/server-side JavaScript for BFF or middleware layers.
- Experience articulating frontend architecture or design-pattern guidance or contributing to internal platforms and developer-facing tooling at scale.
