About the Role

We are looking for a Frontend Engineer to join our Web Tooling team, which is responsible for the foundation that hundreds of engineers across Wolt, DoorDash, and Deliveroo rely on to build internal operations tools. This role offers the opportunity to solve challenging engineering problems with visible impact across the business, combining product engineering with platform thinking and improving developer workflows.

Responsibilities

Owning the Foundation: the runtime, build, deployment and developer experience that 200+ MFEs and hundreds of engineers depend on every day.
Evolving Our Micro-Frontend Architecture: improve composition, isolation, and shared dependency strategies so feature teams can move fast.
Product and Planning: Independently drive projects from idea to production: breaking down ambiguous problems into clear technical plans, estimating delivery, identifying risks early, and delivering high-quality solutions in a timely manner.
Supporting Engineering Excellence: champion best practices, raise the bar for code quality, and turn lessons learned into platform improvements.
AI Fluency: Use AI coding tools to increase engineering productivity and quality, while applying strong judgment and review.
Long-Term Thinking: balance short-term feature unblockers with the long-term health, security, and maintainability of the platform.

Requirements

Proven expertise in building production frontend applications using TypeScript and React.
Solid backend knowledge, comfortable owning and operating Node.js services that support frontend infrastructure.
Strong knowledge of frontend build tools, bundlers, and module systems, and the ability to evolve them as the platform grows.
Track record of diagnosing and resolving complex performance, reliability, or DX issues in large frontend codebases.
Experience driving technical initiatives across multiple engineering teams and stakeholders.
Strong communication skills and a collaborative, platform-mindset approach to working with feature teams.
Strong documentation skills, including experience writing RFCs or ADRs.
Experience with micro-frontends architecture.
Frontend platform engineering experience.
Experience building shared component libraries used by many product teams.
Hands-on experience with CI/CD pipelines, deployment processes, and cloud infrastructure for frontend workloads.
