About the role

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).
