Frontend Engineer, Platform

About the role

The Opportunity We're building a dedicated Frontend Platform team, and we're looking for a Frontend Engineer who loves working on the systems that every product team builds on. You'll own the design system and the horizontal web foundation — the shared components, patterns, architecture, and tooling that let every team ship consistent, high-quality experiences without reinventing the basics.

Responsibilities

• Own and evolve our design system — architecture, tokens, theming, governance, and the patterns product teams rely on, in close partnership with Design Engineering
• Build the horizontal web foundation: shared components, frameworks, and the architecture that product teams build features on top of
• Improve performance, accessibility, and consistency across all web surfaces — making quality the default rather than something each team re-solves
• Develop the tooling and developer experience that help product teams move quickly and confidently, including an AI-forward approach to frontend development
• Partner with product and engineering teams to bring platform capabilities into their workflows, and contribute improvements back from real product needs
• Create the documentation and guidance that make all of the above easy to adopt

Requirements

5+ years of frontend or full-stack engineering experience, with a track record of work that other engineering teams depended on

Experience building or scaling design systems, component libraries, or shared frontend infrastructure — with an instinct for horizontal impact over one-team feature work

Fluent in modern frontend technologies (JavaScript/TypeScript, React, Next.js, CSS systems)

Strong understanding of accessibility (WCAG) and web performance as shared, systemic concerns

Comfortable with AI-assisted development (AI tools are part of our daily workflow and our interview loop)

Communication skills and ability to influence engineering and UI standards across teams

A founder's mindset: ownership, speed, pragmatism, and bias toward action

Qualifications

Experience with experimentation/feature-flagging, localization (i18n), or accessibility tooling at a systems level

Monorepo or frontend build tooling experience (Turborepo, Nx, Vite)

Worked as a product engineer before moving toward platform — you understand both sides

Skills

Experience with modern frontend technologies (JavaScript/TypeScript, React, Next.js, CSS systems)

Understanding of accessibility (WCAG) and web performance as shared, systemic concerns

Comfortable with AI-assisted development (AI tools are part of our daily workflow and our interview loop)
