> Design Engineer owning the component library and design system for an enterprise AI platform. Hands-on IC role building reusable components in React/TypeScript while collaborating with designers and engineers.

## Job Description

## Responsibilities
- Own, build, and maintain our common component library — designing reusable, accessible, well-documented components and implementing them in production front-end code.
- Establish and uphold design patterns across the platform: define conventions, keep them consistent across products and surfaces, and evolve them as needs change.
- Keep the system ahead of the platform's growth — anticipate new patterns, refactor and extend components, and prevent drift and one-off implementations as the product expands.
- Bridge design and engineering: translate high-fidelity designs into faithful, performant, reusable UI, and feed real implementation constraints back into the design process.
- Build prototypes and reference implementations that show how new patterns should look and behave in code, not just in mockups.
- Partner with product designers, PMs, and engineers to align on vision, ensure technical feasibility, and ship at a high quality bar.
- Champion accessibility, performance, and consistency as first-class properties of the system.
- Maintain the system's health over time: versioning, documentation, migration paths, and developer ergonomics so the rest of engineering can move fast on top of it.

## Requirements
- 4+ years working at the intersection of design and front-end engineering (design engineer, UX engineer, design systems engineer, or a front-end engineer with strong design sensibility).
- Strong front-end engineering skills: production experience with React and TypeScript, modern CSS, and component-driven architecture.
- Demonstrated experience building and maintaining a component library or design system that real teams shipped on top of.
- A strong eye for interaction and visual detail: you can design a component, not just implement someone else's spec.
- Deep care for accessibility, performance, and cross-surface consistency.
- Fluency in Figma and an understanding of how design tools and code should stay in sync.
- Systems-level thinking: you design and build for reuse and scale, not one-off screens.
- Excellent communication and a collaborative, proactive mindset; comfortable owning an area end to end.

## Nice to Have
- Experience with design-system tooling (Storybook, tokens, automated visual/regression testing, monorepo setups).
- Experience designing or building for AI-native, agentic, or data-intensive products.
- Familiarity with ERP, CRM, HCM, or other systems of record.
- Comfort operating in a fast-moving, early-stage environment.
- Experience prototyping AI-assisted tools (e.g., Cursor or similar).
