A Principal Engineer role with no backlog of your own. Instead you get the run of 15 teams, on a consumer platform that deploys well over a thousand times a month, with one brief: make every team better, faster and sharper at building with AI.
If you already ship to production with Claude Code or Codex, if you can’t help eyeballing Core Web Vitals like a scoreboard, and if you actually enjoy making the people around you sharper, this one’s for you.
It’s one of the UK’s biggest consumer platforms. Proper scale, deploying well over a thousand times a month. You’d sit in a small, senior team that doesn’t own a backlog of its own. You drop into other teams, pair on the hard stuff, fix what’s broken and spread what’s working.
Right now they’re rolling AI out across the whole business, and this team is the one leading it.
The day to day:
- You’re in the teams, hands on, coaching as you go.
- You set the bar for how they build with AI, in how they work and what they ship.
- You own front‑end performance (Core Web Vitals, speed, accessibility) on pages that take serious traffic.
- Some of it is your own time to explore, a lot of it is making everyone else better.
- You’ll get out and talk about the work too: blogs, talks, the lot.
The AI side, and this is the big one:
They’re already a long way down the road. Most commits are AI‑assisted now. So this isn’t a role for someone keen to learn it, it’s for someone already doing it.
I want to see you shipping real things to production with Claude Code or Codex, with proper opinions on guardrails, cost, and not letting the AI quietly think for you. Tell me where it’s worked brilliantly and where it’s bitten you. If your current place hasn’t let you near any of this, a side project that proves you’ve cracked it yourself does the trick.
The rest of it:
- Front‑end performance isn’t optional. Core Web Vitals and speed need to be second nature, ideally off the back of an e‑commerce or high‑traffic consumer business.
- React and TypeScript lean is great, but they care more that you pick new things up fast.
- You’ve got to be someone who lifts the room. You might not call yourself a coach, but if you’re the right person, you already are one.
