Job Description & How to Apply Below
Location: Greater London

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.

What You’ll Be Doing
  • Owning product features from idea to production launch
  • Building polished front‑end experiences using Type Script / Next.js
  • Developing backend services and APIs using Node.js
  • Building AI‑adjacent features such as:
  • document processing workflows
  • internal operations tooling
  • Working closely with operations and commercial teams to solve real user pain points
  • Shipping quickly in a highly iterative product environment
  • Helping shape engineering culture and standards
What They’re Looking For
  • 2–7 years experience in full‑stack engineering
  • Strong front‑end skills with Type Script / Next.js
  • Commercial backend experience with Node.js
  • Product‑minded engineer who cares about users and speed
  • Comfortable working in ambiguity and startup pace
  • Strong work ethic and desire to build
Nice to Have
  • Experience in startups or top‑tier tech businesses
  • Exposure to AI products or automation systems
  • Familiarity with GCP, Postgres, Terraform
  • Experience in fintech / insurtech / workflow‑heavy products
Package
  • Meaningful equity
  • High ownership, high impact environment
Why This Role?

This is ideal for someone who wants to move faster, own more, and build products that genuinely matter — rather than being one small cog inside a large company.

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