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.


What You’ll Be Doing

  • Owning product features from idea to production launch
  • Building polished front-end experiences using TypeScript / Next.js
  • Developing backend services and APIs using Node.js
  • Building AI-adjacent features such as:
  • document processing workflows
  • email automation
  • communication / voice pipelines
  • 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 TypeScript / Next.js
  • Commercial backend experience with Node.js
  • Experience owning features end-to-end
  • 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

  • £80k–£150k base salary
  • Meaningful equity
  • Visa sponsorship available
  • 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.
