About the role

Every pixel we ship has to earn their trust.
That means making sophisticated automation feel legible, making audit trails obvious, and making reviewers faster without ever making them guess what the agent just did.
The bar: code that holds up at scale and interfaces that feel considered down to the last interaction.

Own the design system in code. Build, maintain, and evolve the components, primitives, and patterns the rest of the product is built on. Make decisions that constrain future work in healthy ways. This is the role's center of gravity.
Ship the production version of design-heavy work. Take concepts from prototype to production-grade front-end code. Hold the line on performance, accessibility, and reliability for interfaces that compliance analysts use for hours at a time.
Design and build the interface patterns that earn that trust without overwhelming the default experience.
Partner with our product designer on direction. Validate ideas through working code, push back when something won't hold up in production, and turn shared decisions into shipped interfaces.
A systems mindset: interest in building primitives others compose with, and judgment about what belongs in the system versus what stays bespoke
Experience contributing to or owning a design system or front-end component library
Own the design system in code.
Comfort in Figma for design system work

Collaborate with the engineering team on architecture, integration, and the long-term health of the front-end.

What we're looking for Significant production front-end experience, with examples of interfaces you owned from concept through shipped code
Care for performance, accessibility, and reliability as part of how you define craft, not as separate concerns
