About the role

You will build the websites, apps and internal platforms our clients run their business on — front end to database, and the pipelines in between.

Every change you ship passes the same gates: tests, Core Web Vitals and WCAG 2.2 AA budgets in CI, and a human review. Coding assistants are part of the toolkit, and AI-proposed code gets exactly the same scrutiny as yours. You will also mentor mid-level engineers and help set the standards they learn from.

What you will do

  1. Ship features across a TypeScript front end and Node or Python services
  2. Hold Core Web Vitals (LCP ≤ 2.5 s, INP ≤ 200 ms, CLS ≤ 0.1) and WCAG 2.2 AA budgets in CI
  3. Review AI-proposed code with the same rigour as human code
  4. Design data models and APIs that another team can pick up without a meeting
  5. Mentor mid-level engineers through pairing and review

A typical week

Where the hours go in an ordinary week, and which parts agents carry. Whatever an agent drafts or checks, a person decides what happens next.

  1. Building features

    You write it with a coding assistant in the loop; nothing merges without tests and your own review of every line.
