Senior Frontend Engineer (React and Next.js)

LocationLondon or remote, UK
Job typeFull time
Experience levelSenior
DepartmentEngineering

You will build the interfaces our customers and our team use every day: the approval queues, the weekly briefs, the agent controls and the internal tooling, plus the website you are reading now.

Responsibilities

  • Build and maintain the customer console: approvals, logs, agent settings and the weekly brief.
  • Build internal tooling for the delivery team to configure, test and monitor agents.
  • Own the website and its illustration and animation system.
  • Care about accessibility, performance and the details that make software feel considered.
  • Work with design and engineering to ship small, often.
  • Review code and raise the standard of the front end across the team.

What we are looking for

  • Five or more years building production web applications with React and Next.js.
  • Strong TypeScript and a good understanding of the browser.
  • Experience designing interfaces for non-technical users under time pressure.
  • An eye for typography, spacing and motion, and the judgement to use them sparingly.
  • Comfort working from a brief rather than a finished design.

Helpful, not required

  • SVG and animation experience (GSAP or similar).
  • Experience with design systems and component libraries.
  • Familiarity with Claude or similar tools in your own workflow.

How we hire

  • A short call with a founder to talk about the role and what you have built.
  • A practical exercise close to the real work, paid for your time, with a follow-up conversation about it.
  • A conversation with the people you would work with most.
  • An offer within a week of the last conversation. We tell you either way.
