AI Engineer – Up to £115,000 – London Hybrid (2 days a week) A high-impact AI Engineer hire inside a fintech business building production-grade AI products from the ground up.
This is a rare opportunity to join a small, fast-moving AI team with real ownership over greenfield products — shipping GenAI applications that directly influence how a market-leading lending platform operates.
⚡ Greenfield AI | Real ownership | High-impact team
The Opportunity Join a cross-functional AI and Machine Learning team operating like a startup within an established, publicly listed fintech business.
Projects are 80–90% greenfield. You’ll bridge the gap between data science POCs and production-grade systems, owning AI products from experimentation through to live deployment.
This is a role for engineers who want to build, ship and own — not just advise.

Own how AI systems integrate with existing product infrastructure Handle real-world failure states and production engineering decisions Collaborate closely with data scientists, platform engineers and PMs Contribute to best practices for AI product development across the business Mentor teammates and stay current in a fast-moving space
You’ll work exclusively in Python with FastAPI. Strong software engineering fundamentals matter here as much as AI experience.
What You’ll Be Working On Website chatbot and conversational AI products Internal AI tooling and automation Document processing pipelines RAG pipelines, LLM integrations and agent frameworks Taking POCs to production-grade systems at scale
Skills and Experience Strong Python engineering fundamentals — this is an engineering role first Hands-on experience with GenAI, LLMs, RAG or agent frameworks Product mindset with comfort owning end-to-end delivery Actively using AI tools in your own workflow (Claude, Copilot etc.) Fast-learning and motivated to move with a rapidly evolving space
Nice to have: Full-stack experience (JavaScript/TypeScript) Experience taking AI products from POC to production commercially
Location: London – Hybrid (min. 2 days/week) Compensation: Up Up to £115k + bonus Team: Small, collaborative, fast-moving — high ownership culture Stage: Greenfield AI products inside an established, scaled business
We’re hiring for both Mid and Senior levels — if you’re genuinely building in AI and want real ownership over products that matter, this is worth a conversation.
