About the role

Senior frontend engineer focusing on building Doppel's platform-level frontend infrastructure, design system, and design-to-production pipeline to enable product teams to ship features without frontend plumbing, with an emphasis on React/TypeScript, AI-assisted development, and scalable, safe primitives.

Responsibilities

  • Build and maintain the frontend infrastructure every product runs on: the application shell, data layer, routing, auth, and build/deploy pipeline — so product teams ship features, not frontend plumbing.
  • Evolve the design system from a component library into a contract: constrained, composable primitives with tokens, docs, and guardrails tight enough that generated code is correct by construction.
  • Build the design-to-production pipeline: the tooling, agent workflows, and review guardrails that let designers and product teams go from a design to a shipped, production-quality surface without hand-writing frontend code.
  • Make the platform safe by default: permissioning and packaging gates, observability, accessibility, and internationalization baked into the primitives rather than re-implemented per feature.
  • Own production health of the shared client: monitors, SLOs, and ownership routing so failures page the right team automatically and the platform stays trustworthy enough to build on blindly.
  • Package the platform for scale: a versioned component library and scaffolding that lets new apps and product surfaces spin up on the paved road from day one.
  • Partner closely with design and product teams as your customers — their velocity is your success metric.

Qualifications

  • 5+ years of software engineering experience with deep expertise in React and TypeScript, building and operating production web applications.
  • Experience owning platform-level frontend work: design systems, component libraries, build tooling, data-layer patterns (Relay or similar GraphQL clients), or frontend infrastructure other engineers build on.
  • Genuine excitement about AI-assisted development — you see agents as a way to raise the abstraction level of frontend work, and you want to build the rails that make that safe.
  • A platform mindset: you measure success by what other teams (and designers) can ship without you, not by features you shipped yourself.
  • Comfort operating in ambiguity — the team's charter is being defined in real time as the company grows, and you'll shape it rather than inherit it.
  • Familiarity with production monitoring and performance work (RUM, SLOs, error budgets) is a strong plus.
  • Experience collaborating deeply with designers — design tokens, Figma workflows, Storybook-driven development — is a strong plus.
  • Strong communication skills: your customers are product teams, designers, and backend platform engineers.
  • Product-minded, highly autonomous, and comfortable in a fast-paced startup environment.
