Job Description

Unity is AbbVie's enterprise design system — the shared tokens, components, standards, and documentation that enable rapid, compliant, high-quality digital product delivery at scale. The Unity Design System team is transitioning Unity into a fully AI-enabled, agent-ready platform: AI-assisted design-to-code, Claude Code skills, MCP integrations, and AI-driven UI delivery, with humans in the loop to curate, approve, and evolve standards. This role sits on the developer-facing side of Unity. The person in this seat is a hands-on, full-stack-leaning engineer and the visible “face” of Unity development — building the React component library and developer tooling, pioneering agentic AI workflows, and serving the 600+ member developer community as a trusted, go-to resource.

Work collaboratively across the Unity Design System team, BTS, and AbbVie's developer and design communities to conceive, design, engineer, and deliver developer-facing components, tooling, and AI-assisted workflows that accelerate compliant, high-quality digital product delivery across the enterprise. Serve as a hands-on senior builder across the full stack — React/TypeScript components and design tokens, Python/Node.js services and automation, and agentic AI integrations — while operating autonomously: gathering requirements directly from developers, QA testing your own work, deploying, and closing fast feedback loops. Establish trust and credibility as the go-to resource for Unity development needs and act as the developer-facing face of the design system.

Responsibilities

• Design, build, test, and maintain reusable, accessible React/TypeScript components for the Unity React library, with deep attention to design tokens/tokenization, theming (light/dark, density modes), composability, and Storybook documentation.
• Build and pioneer AI-assisted and agentic developer workflows — Claude Code skills, MCP server integrations (Figma, Storybook), context/markdown files, and prompt-to-code / design-to-code pipelines — that enable both developers and AI agents to deliver Unity-compliant UI at scale. (Claude Code skills experience is required.)
• Develop full-stack supporting services, front-end automation, and build/release/validation tooling using Python and Node.js (CI/CD, design-ops, compliance checks).
• Own quality end-to-end: write and maintain automated tests, perform accessibility (WCAG 2.2 AA) and cross-browser QA using the team toolstack (Storybook, Axe, GitHub), and QA your own work before release.
• Act as the developer-facing face of Unity — provide community support, outreach, and management; build relationships, run demos/office hours/presentations, and establish trust and credibility as the go-to resource for Unity development.
• Work autonomously to gather and generate requirements directly from developer-community needs, translate them into actionable work, and communicate back to the team with quick feedback loops.
• Contribute to Unity's data-visualization capabilities and support data-science-driven features, applying a data-science background and data-visualization experience where applicable.
• Wear multiple hats and context-switch as a co-owner of team responsibilities across requirements, development, QA/testing, deployment, application development, community building, and presentations.
• Stay current with state-of-the-art AI development and productivity tooling; pilot, evaluate, and roll out improvements (e.g., Storybook MCP, AI documentation, new productivity tools) across the team.
• Provide technical leadership and mentor less-experienced staff; partner with designers, brand, accessibility, and BTS stakeholders; and adhere to corporate standards including code of conduct, data security, GxP compliance where applicable, and the software development lifecycle.

Qualifications Required:

• Bachelor's Degree with 6 years' experience; Master's Degree with 5 years' experience; or PhD with 0 years' experience.
• Seasoned front-end engineer with expert React and TypeScript skills, strong HTML/CSS, and proven design-system / component-library development experience.
• Strong understanding and awareness of design tokens / tokenization and scalable theming.
• Hands-on agentic AI and AI-workflow development experience; demonstrated ability to build Claude Code skills (required) and AI-assisted developer tooling.
• Backend and full-stack capability with Python and Node.js.
• Proficiency with the team toolstack: Storybook, GitHub, and accessibility/WCAG testing tools (e.g., Axe).
• Strong testing and QA discipline — consistently QAs own work.
• Experience building products for a developer-facing audience, with the ability to “meet developers where they are.”
• Proven ability to work autonomously, generate and gather requirements, and operate with fast feedback loops while wearing multiple hats and co-owning responsibilities.
• Excellent written and oral English communication; strong community outreach and relationship-building; a proactive, collaborative team player.

Preferred:

• Developer skills beyond JS/React (e.g., Angular, additional languages/frameworks).
• Data science background and data-visualization experience.
• Front-end automation experience.
• Familiarity with MCP servers (Figma MCP, Storybook MCP), Figma / Code Connect, and OutSystems.
• Experience with developer relations (DevRel) and community management.
• Mobile development experience (nice to have).
