Founding Engineer — AI Agents | Onsite | Python/TypeScript | £££ + 1–1.5% Equity
I’m supporting a hyper-growth AI startup that’s building next-generation AI agents—automation systems capable of reasoning, planning, and executing complex workflows end-to-end. They’ve secured serious early traction, are backed by top-tier investors, and are now growing the core engineering team at speed.
This is a chance to join as a Founding Engineer and help shape the architecture, product direction, and engineering culture from day zero.
What you’ll do:
* Design and build production-grade AI products & agentic systems
* Own major parts of the codebase across Python or TypeScript
* Work directly with founders to define tech strategy, system design, and go-to-market execution
* Ship fast, iterate with real users, and turn ideas into working features rapidly
* Build scalable, reliable, high-performance systems from scratch
What we’re looking for:
* 4–10+ years engineering experience
* Strong expertise in Python or TypeScript
* Experience with AI/LLM-powered products, agentic workflows, or automation systems
* A startup mindset — comfortable moving quickly, wearing multiple hats, and owning 0→1 builds
* Someone who thrives in high-calibre teams and wants to be surrounded by top engineers
What you’ll get:
* Competitive salary
* 1–1.5% equity (founding-level ownership)
* Work onsite with a world-class founding team
* Build core systems that directly shape the future of the company
* Huge technical scope and real product influence
If you're excited by the idea of building AI agents at the ground floor of a breakout startup, this is one of the most impactful roles you’ll find.
