Product Builder

At Heart Mind Talent we're supporting a fast-growing AI startup on the search for a Product Builder to join their team.

The company is building an AI-powered product helping millions of households manage and optimise their bills, combining agentic communication, GenAI data extraction, workflow orchestration, and recommendation systems.

This is not a traditional product or engineering role, as you'll own a product surface and make it better end to end, without waiting for an engineer to do it for you: from their customer-facing Whats App agent, to the Open Banking data behind their subscription product, to whatever's most broken.

You'll work alongside engineers who build the safe surfaces you ship on, and get hands-on yourself, using AI tools like Claude Code and Cursor to prototype, query data, and ship changes to the live product.

• Take a product problem from rough to shipped, with AI tooling as your main working environment
• Answer your own questions by writing the query, not filing a ticket and waiting
• Ship on safe surfaces: prompts, agent behaviour, configuration, workflows, data pipelines and internal tools
• Live close to the user, reading real conversations and letting them drive what you build next
• Own the outcome, because a feature is only done when it's working for members

• This role is ideal for someone with a technical foundation who loves building product
• You might be an engineer who moved into product, a technical PM, a former founder, or the generalist who ends up owning the thing nobody else will

• A technical foundation: a CS or engineering degree, or time as an engineer or technical PM
• Technically fearless: comfortable reading code, writing some SQL, and knowing when to ask for help
• Strong product judgement, framing problems around what changes for the user
• You've owned something real and shipped things people actually use

• Join a high-growth AI startup solving a massive consumer problem
• Be the first person hired directly into a new way of building product
• High ownership in a team with very little middle management
• Small, ambitious team where everyone builds
• Compelling package including share options

This is a London-based, office-first role
