Senior AI/ML Modelling Engineer

Senior AI/ML Modelling Engineer Remote (UK/Europe) | Contract We're partnering with a well-funded technology business building a next-generation AI platform focused on solving complex financial decision-making problems. This is not a traditional software engineering or data science role. We're looking for someone who combines exceptional machine learning expertise with a strong quantitative mindset and an understanding of how financial decisions are made. You'll work on designing intelligent modelling systems that help evaluate opportunities, assess risk and improve decision-making using modern machine learning and generative AI techniques. What you'll be doing • Designing and deploying production-grade machine learning models using regression, classification and gradient boosting techniques • Building LLM-powered and agentic AI workflows using modern frameworks such as LangChain, LangGraph, AutoGen or similar • Developing end-to-end AI systems from data ingestion through to decision support • Applying AI and machine learning to complex financial and investment problems • Working with structured and unstructured datasets where data quality is often imperfect and limited • Building explainable models that support transparent, defensible decision-making • Collaborating with technical and domain specialists to translate complex business challenges into scalable AI solutions We're looking for someone with • Exceptional machine learning fundamentals and strong commercial experience building production ML systems • Hands-on experience with LLMs, transformer models and agentic AI frameworks • Strong Python development skills • Experience building end-to-end AI platforms rather than isolated models • Excellent product thinking and the ability to solve ambiguous problems Highly desirable • Experience within private credit, private markets, lending, investment management or quantitative finance • Understanding of concepts such as EBITDA, cash flow analysis, underwriting, portfolio construction or credit assessment • Experience building predictive models for financial decision-making, risk assessment, pricing or scoring • Ability to work with sparse, messy or low-volume datasets where model interpretability is essential • Experience communicating model outputs to non-technical stakeholders and balancing predictive performance with explainability The opportunity • Greenfield AI platform with significant technical ownership • Complex modelling challenges with real commercial impact • Small, high-calibre engineering team • Long-term contract • Remote across the UK and Europe
