I am working with several Series A-C FinTech AI companies hiring Senior ML Engineers and Senior AI Engineers across the UK right now. Not LLM wrappers – real production systems. Risk modelling, fraud detection, agentic compliance, transaction intelligence, retrieval‑augmented generation pipelines running over financial data in regulated environments.

Companies that have closed funding in the last twelve months and are scaling the engineering team that has to make AI actually work inside Financial Services.

Technical bar (broadly):

• 5+ years building and shipping Machine Learning systems in production
• Strong on the modern AI stack – PyTorch, HuggingFace, LangChain, LangGraph, vector databases and RAG pipelines
• Comfortable owning a model end‑to‑end: data, training, evaluation, deployment and monitoring (MLOps / LLMOps)
• Bonus ball: exposure to regulated environments – FinTech, banking, payments, insurance
