Lead Full Stack Engineer (AI/Agentic)

Company: hedgehog lab
Apply for the Lead Full Stack Engineer (AI/Agentic)
Location: London
Job Description:

You’re the kind of engineer who sees a legacy codebase as a problem worth solving. You’re comfortable across the full stack, you take agentic engineering seriously, and you want to influence technical direction rather than just execute against it.

You’ll be embedded into the product team of one of the UK’s leading procurement platforms as your first project here. The platform connects organisations managing construction projects with the suppliers who deliver them. It’s high‑traffic, mid‑transformation, and the architectural decisions that will define its next five years are still being made.

The stack today is PHP/Laravel. That’s where you’ll start, and we’re not going to pretend otherwise. The direction of travel is Python and a more modern, AI‑native architecture. You’ll be part of shaping how it gets there.

What We’re Looking For

  • Comfortable working across PHP/Laravel and Python in commercial, production environments
  • Strong experience at Lead or Senior Full Stack level
  • Has shipped LLM or agentic tooling into real systems, not just experimented with it
  • Knows AWS and has built scalable, cloud‑native APIs before
  • Has enough front end range to work with React.js or Laravel Nova when needed

Here’s What You Get In Return

You’ll be in the room when the big architectural decisions are made, not handed them after the fact. Your technical judgment will carry real weight here.

You’ll also be asked to do more than write code. The limit on agentic engineering isn’t what you can produce, it’s your ability to communicate clearly, spot problems early and define what good looks like. If that’s already how you work, you’ll find this role fits the way you think.

Working here means you’re building agentic engineering experience across multiple clients and contexts, not just one. That’s a different kind of career development than most roles can offer.
