Senior Front End Engineer

What we're looking for

• 6+ years of professional frontend engineering experience, with deep expertise in React.js and TypeScript.
• Strong architecture and system design skills: you write RFCs, define clean client–server boundaries, and think hard about scaling trade-offs.
• Solid testing discipline: testing is part of how you write code, not something you bolt on at the end.
• Performance and accessibility matter to you: you profile, you measure, you ship interfaces that work for everyone.
• AI is part of how you work. You've got a real workflow (not just occasional autocomplete) and you know when to trust the model.
• You can run with ambiguity. Take a fuzzy problem, write the RFC, ship it, push back on bad ideas along the way.

Nice to have

• A bit of backend Golang on top of your frontend skills.
• You've built or maintained a design system or component library.
• You've shipped AI or LLM features in production.
• You're comfortable with frontend observability.

What you'll do

• Lead frontend architecture decisions for a platform serving thousands of concurrent agents across Wolt, DoorDash, and Deliveroo.
• Design and build responsive, accessible, performant interfaces using React + TypeScript.
• Author architecture and design documents (RFCs) that align cross-functional teams on technical direction.
• Partner closely with product, design, and backend engineers to ship automations and AI-powered features that meaningfully boost agent productivity.
• Set the bar for engineering quality through rigorous code review, performance audits, testing standards, and operational readiness.
• Debug, profile, and optimize the platform for performance, accessibility, and reliability across browsers and devices.
• Mentor other engineers and raise the team's overall technical depth.
