Founding AI Engineer

Founding AI Engineer Up to £130k equity London (5 days on-site) Be part of the founding team at an early-stage Fintech. Best suited to someone who enjoys building and shipping. Opportunity to build an AI native toolkit from scratch. I’m looking for a Founding AI Engineer to join a very early-stage (Pre Seed) startup in London. This role is best suited to people who thrive working in highly ambiguous environments and are happy to pivot at the drop of a hat. Startup life isn’t for everyone, so you really need to be someone who gets excited by the idea of wearing many hats and getting stuck in. The good news is that the business has two years of runway based on funding alone, and the even better news is they’re already revenue generating! Being part of the founding team means you’ll have the opportunity to build an AI native toolkit from the ground up. If having a tangible impact on the core product and overall success of the business is something that excites you, then this role is for you. The preferred option is to find people who have come through the software engineering route into AI, as opposed to the more traditional route of Data Scientist/ML Engineer. By this I mean you’ll need to be comfortable writing and shipping code and working on AI APIs, less so model building, fine-tuning LLMs, etc. Essential requirements: Founder type mindset with a strong product lens. You value speed and scale over perfection. Highly autonomous. Experience building AI agents/agentic systems/architecture/RAG pipelines. Software engineering background. Experience developing and deploying production application layer products. Enjoy the buzz of startup life and want to work with high energy people. Just to highlight, this role is 100% on-site. You will need to be happy being in the office more often than not. Unfortunately, sponsorship is not available for this role. Reach out to Jamie Forgan for more information.
