## About the Role

Do you have experience in TypeScript?, Do you have a Master's degree?, * 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.

## Description

* 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.
