Product Engineer - London (On-site) | £100,000 to £150,000 + equity | Full-time
About the company
A YC-backed AI startup that is about to close a significant Series A. They’re rebuilding a large, traditional industry that still relies on slow manual processes, and they’ve grown rapidly over the last year with a strong list of enterprise customers.
The role
This is a hands-on engineering role that sits very close to the people using the product. You’ll find where work gets stuck, build AI-powered tools and agents to fix it, and get them into production quickly. The loop between spotting a problem and shipping the fix is short, so you’ll see the impact of your work almost straight away.
What you’ll be doing
- Spending time with internal users to understand their workflows and pain points
- Designing and building full-stack features and AI agents from idea to production
- Working with the AI and operations teams to make sure automations are reliable and safe
- Improving systems as usage grows
What they’re looking for
- Strong full-stack experience, ideally TypeScript, React and Node
- Hands‑on experience building with LLMs, ideally systems that take actions rather than just answering questions
- Comfortable owning features end to end without detailed specs
- Thinks carefully about what happens when automation gets it wrong
- Startup experience is a plus. Drive and pace matter more than years of experience
What’s on offer
- £100,000 to £150,000 base plus meaningful equity
- 30 days a year working from anywhere, separate from annual leave
- Private medical, pension and a fast-track promotion path
- On site in Central London with a high-energy team
