Frontend Engineer, Web Tooling

Wolt is looking for a Frontend Engineer to join our Web Tooling team. The team sits within the DoorDash Developer Platform group and is responsible for the foundation that hundreds of engineers across Wolt, DoorDash and Deliveroo rely on to build internal operations tools. Our platform hosts 200+ micro-frontends (MFEs) used to operate every part of the business.

About the team

Our team is focused on building a scalable, reliable, and high-quality internal tooling platform that supports Wolt, DoorDash, and Deliveroo’s operations and business.

The team plays an important role in improving how engineers build, test, and ship software across the organization with a strong emphasis on reusable libraries, micro-frontend architecture and harness engineering for AI coding agents that enable teams to move faster while maintaining high quality.

Right now, we are focused on unifying our frontend platforms, evolving shared components and library development, improving developer productivity, and enabling teams to deliver more independently through better architecture and tooling.

It’s an exciting time to join because the team has strong ownership and a broad technical impact.

About the role

We’re looking for a Frontend Engineer who can take ownership of complex technical initiatives across both frontend and sometimes backend domains. In this role, you’ll work primarily with TypeScript, React, Node.js, CI/CD pipelines, and MFE architecture to build scalable, maintainable solutions that support multiple product teams and business areas.

Success in this role means becoming a trusted technical owner who consistently delivers reliable solutions, and helps the team execute more effectively. Six months into the role, we’d expect you to be independently leading technical initiatives and contributing meaningfully to architecture and delivery planning.

This role offers the opportunity to solve challenging engineering problems with visible impact across the business. It’s especially exciting for someone who enjoys combining product engineering with platform thinking, improving developer workflows, and building systems that scale across teams and domains.

What you’ll be doing

• 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.

📍This role can be based in one of our tech hubs in Helsinki or Berlin. Read more about our hybrid setup here.

• 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.

Nice to haves

• 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.

What’s in it for you

• Impact: Build and shape the platform that thousands of people depend on.
• Scale: Work on real platform problems behind 200+ MFEs with hundreds of monthly contributors.
• Collaboration: Partner with talented engineers, designers, and operators across companies to make their daily work faster and better.
• Growth: Take on deep technical challenges across frontend architecture, AI harness engineering, DX, performance, and improving engineering efficiency.
• Culture: Be part of a diverse, open-minded team that values creativity, autonomy, and continuous learning.
