CTO - AI Startup

CTO | YC-Backed AI Startup | London | £115–130K + significant equity

Two types of people will love this role.

An experienced Engineering Lead or Head of Engineering who is ready to make the step up into a CTO position - with the right environment to do it in.

Or a startup CTO who wants to get into something early, own the technical direction from the ground up, and hold meaningful equity before the next funding round.

Either way - the product is live, the engineering team is in place and shipping, and the business is already generating revenue across the US and UK, with European expansion underway. This is a technical leadership hire into a working product, not a blank slate.

The platform is built on a large-scale proprietary dataset, powered by LLMs and agentic workflows. The engineering challenge is genuinely complex - the kind of problem that will stretch and excite a serious technical leader.

The team is small, talented, and needs someone who will lead from the front and still get their hands dirty.

Must haves:

• Hands-on engineering leadership at one or more early-stage startups
• A track record of shipping real products at scale
• Founder DNA - you've built something yourself or have operated at founding-team level
• Experience hiring and growing small engineering teams
• Active hands-on coder - Python and/or TypeScript

• Data-first background - pipelines, databases, and large-scale data modelling
• Comfortable owning AI/LLM tooling end to end, not just evaluating it
• London-based - you enjoy being in the office and value in-person collaboration, with some flexibility

Strong plus:

• Experience in regulated industries - healthcare, pharma, fintech
• Graph database or large-scale data pipeline experience
• Elasticsearch at scale
