Job Description
Full-Stack Product Engineer
London | £80k–£150k + Equity
A well-funded, fast-growing AI startup is hiring a Full-Stack Product Engineer to help build the next generation of operational software in a large, legacy industry being transformed by automation.
This is an opportunity to join early, work directly with founders, and own high-impact product features from day one. The business has strong funding, rapid growth, and real-world product-market fit.
The Role
You’ll join a lean, high-performing engineering team building internal and customer-facing products powered by AI.
They’re particularly keen to hire someone with strong front-end capability who can complement an existing backend-heavy team, while still being comfortable shipping across the stack.
You’ll own features end-to-end — from understanding user problems, defining solutions, building the product, and iterating quickly based on feedback.

- Building AI-adjacent features such as:
- document processing workflows

- Product-minded engineer who cares about users and speed

Why This Role?

If you're strong technically, commercially minded, and want to be part of a category-defining company early, this is worth a conversation.
