Lead Full-Stack Engineer | Path to CTO | AI-Native Fintech Cash + Meaningful Equity

We’re helping an ambitious fintech startup hire a hands‑on Lead Full‑Stack Engineer to bring its engineering capability in‑house and help build the financial operating system for the next generation.

The company is developing an AI‑native platform designed to make high‑quality financial guidance accessible to millions of people who are underserved by traditional financial advisers.

The product is already in beta, has a growing US waitlist, and the company is preparing for its next major stage of funding and growth.

This is not a maintenance role.

Initially you’ll be expected to get deeply involved in the product and codebase, while gradually taking ownership of the company’s technical direction. For the right person, there is a clear opportunity to progress into the CTO role within approximately 12 months and help build out an engineering team of around five people.

React
• Node.js
• Django
• AI integrations
• Modern cloud infrastructure

• Take technical ownership of a live fintech product as development moves in‑house
• Work directly with the founder to turn product and commercial priorities into shipped software
• Build across frontend, backend and platform infrastructure
• Improve development speed, technical quality and product reliability
• Help make architecture and technology decisions as the product scales
• Recruit, lead and develop the wider engineering team
• Shape the company’s long‑term technical strategy and AI capabilities

• An experienced full‑stack engineer who is still highly comfortable writing code
• Strong across React, Node.js and/or Django
• Experienced in building and shipping real products, not simply contributing to isolated tickets
• Capable of making pragmatic architectural decisions in an early‑stage environment
• Product‑minded and able to communicate effectively with a non‑technical founder
• Comfortable operating with autonomy, ambiguity and changing priorities
• Interested in progressing into a technical leadership or CTO‑level position
• Based in London, or able to work closely with the founder in London

Experience in fintech, financial services, regulated products or AI‑enabled consumer applications would be valuable, but is not essential.

• A competitive combination of cash and meaningful equity
• A genuine pathway to becoming CTO
• Direct influence over the product, architecture and engineering culture
• The opportunity to build an engineering function from the ground up
• A product already in beta, rather than an idea‑stage concept
• Exposure to the US fintech market and an ambitious international growth plan
• London‑based collaboration with flexibility around working arrangements
