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 — component design, hooks, state management, rendering optimization — and frontend performance fundamentals (bundle optimization, lazy loading, profiling) in production
• Solid understanding of asynchronous data patterns (REST/GraphQL API design, WebSockets/SSE) and experience designing or contributing to backend-for-frontend (BFF) layers that mediate between UI requirements and underlying services

Nice to Haves

• Solid testing practices across unit, integration, and end-to-end layers, plus grounding in web accessibility (e.g. WCAG) and frontend security best practices as baseline engineering hygiene
• A working relationship with product design that goes beyond handoff — able to engage at the design stage, push back constructively, and implement pixel-perfect interfaces from high-fidelity specifications
• Strong eye for visual design and interaction patterns, with experience contributing to design systems or component libraries used across multiple teams
• Experience leading the frontend workstream of cross-functional projects in interdisciplinary settings (design, backend, PM, ML), coordinating across multiple engineers and stakeholders
• Experience building annotation, task-editor, or review-tool UIs, or other complex, data-dense productivity interfaces
• Experience with agentic UI patterns — interfaces driven by streaming model outputs, long-running async tasks, and event-driven state — including integrating LLM or agent backends into production web frontends
• Strong proficiency with AI-assisted and agentic coding tools (e.g. Claude Code, GitHub Copilot, Cursor) to accelerate development, paired with sound judgment in reviewing and integrating generated code
• Familiarity with modern frontend tooling and workflows — bundlers (Vite, webpack), testing frameworks (Vitest, Jest, Playwright), CI/CD, and Node.js/server-side JavaScript for BFF or middleware layers
• Experience articulating frontend architecture or design-pattern guidance to an engineering team, or building/contributing to internal platforms and developer-facing tooling at scale

What You'll Be Doing

• Help shape the interfaces through which human expertise and machine intelligence meet
• Contribute to the web frontend of the annotation and quality platform
• Reason through a component architecture and design critique
• Work well in interdisciplinary settings, coordinating across design, backend, and product stakeholders

Perks and Benefits

• Join a team committed to values that lead to great work
• Collaborate with individuals from diverse backgrounds who inspire innovation
• Contribute to building high-quality dataset creation and annotation platforms at Apple
