Skills
Must have
- Master's degree in Computer Science, HCI, or a related field
- Proven professional frontend engineering experience with deep expertise in React and modern JavaScript/TypeScript
- Strong command of React architecture — component design, hooks, state management, rendering optimization
- Frontend performance fundamentals including bundle optimization, lazy loading, and profiling in production
- Solid understanding of asynchronous data patterns (REST/GraphQL, WebSockets/SSE)
- Experience designing or contributing to backend-for-frontend (BFF) layers
Nice to have
- Solid testing practices across unit, integration, and end-to-end layers
- Web accessibility (WCAG) and frontend security best practices
- Ability to engage at design stage and implement pixel-perfect interfaces from high-fidelity specs
- Strong eye for visual design and interaction patterns, with experience contributing to design systems or component libraries
- Experience leading frontend workstream of cross-functional projects in interdisciplinary settings
- Experience building annotation, task-editor, or review-tool UIs or other complex data-dense productivity interfaces
- Experience with agentic UI patterns — streaming model outputs, long-running async tasks, event-driven state
- Experience integrating LLM or agent backends into production web frontends
- Proficiency with AI-assisted and agentic coding tools (e.g. Claude Code, GitHub Copilot, Cursor)
- Familiarity with modern frontend tooling — Vite, webpack, Vitest, Jest, Playwright, CI/CD, Node.js for BFF/middleware
- Experience articulating frontend architecture or design-pattern guidance to engineering teams at scale
Full description
Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other's ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It's the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you'll do more than join something — you'll add something.
As part of Apple's central data annotation engineering team, you will help shape the interfaces through which human expertise and machine intelligence meet. Our platform powers high-quality dataset creation and annotation across every vertical at Apple — from Siri to Photos, from iPhone to Vision Pro. We're looking for a Senior Software Engineer who is product-minded first — someone who reasons about the end-to-end user experience before writing code, owns outcomes rather than shipping to spec, and brings genuine depth in frontend engineering and a designer's sensibility to make that thinking real.
The AIML Annotation Platform provides the tools, frameworks, and services that make large-scale, privacy-focused data annotation possible across Apple. As a Senior Software Engineer on our team, you will be a key contributor to the web frontend of our annotation and quality platform — a complex, multi-role product used daily by annotators, quality analysts, ML engineers, and internal partners worldwide.
You have a mature eye for design systems. You can articulate why a pattern works, spot where an evolving product breaks established conventions, and translate visual and interaction language into guidance that an engineering team can actually use. You are as comfortable reasoning through a component architecture as you are in a design critique — and you bring both rigour and taste to each. That same rigor extends to your engineering craft — you hold a high bar for performance, testing, and architectural soundness in everything you ship.
You work well in interdisciplinary settings, and you bring product judgment to them — asking who uses a feature and what they're trying to get done before settling implementation details, and following up after launch through usage data and real conversations with users to learn what worked.
