Staff Software Engineer

Job Description

As a Staff Software Engineer on the Design System team, you will build and evolve the engineering surface of the design system: the theme system, the design tokens, and the tooling that lets engineers, designers, and product teams apply it correctly. You will work in close partnership with design and product counterparts, and your decisions will ripple across internal product teams and external customers, so systems thinking and a working command of accessibility are as important as your front-end craft. 

Roles and responsibilities 

• Evolve the theme system and its design token architecture, covering token taxonomy, platform transforms, theming APIs, and the guardrails that keep themes accessible. 

• Engineer tooling that makes the design system easy to adopt: theme builders, linting and audit rules, codemods, Figma to code workflows, and local development aids. 

• Build AI skills and tooling that put the design system to work for engineers, designers, and product partners, so prototypes and production code generate on-system by default. 

• Partner closely with design system designers and product managers, weighing design intent, customer need, and engineering cost in every decision rather than optimizing for one. 

• Trace the downstream impact of every change across consuming teams and customer instances, and manage versioning, deprecation, and breaking-change communication accordingly. 

• Hold the system to WCAG 2.2 Level AA, including contrast, forced colors, focus visibility, and reflow, and build automated checks that catch regressions before release. 

• Collaborate with component authors and the component engine team on API contracts, token consumption, and release sequencing. 

• Maintain the enablement surface for the system, including API documentation, usage guidance, and migration paths. 

• Support adopters directly: triage issues, unblock teams, and feed recurring friction back into the roadmap. 

• Raise the bar through technical design review, code review, and mentorship across the design system and consuming teams. 

Qualifications

• 8+ years of professional front-end engineering experience, including significant time building or operating a design system used by multiple teams. 

• Advanced TypeScript and modern JavaScript, with deep command of the browser platform: DOM, events, Custom Elements, and Shadow DOM. 

• Hands-on experience with design tokens: schema design, transform pipelines such as Style Dictionary, and multi-platform or multi-brand distribution. 

• Expert CSS, particularly theming at scale with custom properties, cascade layers, modern layout, container queries, and forced colors mode. 

• Current working knowledge of WCAG 2.2 Level AA and how to apply it to tokens, themes, and components, with hands-on screen reader and keyboard testing. 

• Fluency applying AI tooling in your own engineering practice, including agentic coding tools, and sound judgment about where generated output needs human review. 

• Strong front-end build, release, and versioning skills across tooling such as Vite, Rollup, or Webpack, plus semantic versioning in a monorepo. 

• Demonstrated systems thinking: you reason about cascading impact across dependent teams and customers, and you plan migrations instead of shipping surprises. 

• Proven track record of collaborating as a peer with designers and product managers, and of influencing technical direction across teams without direct authority. 

• Clear technical writing, with experience documenting APIs and guiding other engineers through adoption. 

Nice to have 

• Experience building AI tooling for other engineers, designers, or product partners to use, such as agent skills, MCP servers, or prompt-driven UI generation. 

• Experience building developer-facing documentation or enablement sites.
