Full job descriptionSenior Data Scientist – Loan Deal Scoring & LLM Workflows - (Remote, Outside IR35)
Overview
We’re partnering with a high-performing applied AI team delivering advanced analytics solutions within financial services. They are seeking a Senior Quant Data Scientist to help build next-generation loan deal scoring models combining traditional machine learning, time-series analysis, and LLM-driven workflows.
This is a fully remote, outside IR35 contract with strong likelihood of extension (or potential permanent conversion).
Key Responsibilities
*Develop and deploy ML models for loan/deal scoring (classification, regression, ranking)
*Analyse financial, credit, and time-series data to extract predictive signals
*Build and benchmark models such as: *Gradient boosting (XGBoost, LightGBM, CatBoost)
*Random Forests
*Logistic / linear regression
*Design LLM-powered workflows for: *Document understanding (loan docs, credit memos, financials)
*Risk factor extraction
*Deal-level reasoning and recommendations
*Combine structured ML outputs with LLM-based reasoning to deliver explainable scores
*Work closely with stakeholders to translate credit policy into data-driven workflows
*Support model validation, explainability, and performance evaluation
Requirements
*Strong experience as a Senior Quant Data Scientist
*Deep understanding of: *Regression, classification, and ranking models
*Time-series analysis & feature engineering
*Hands-on experience with: *Python (pandas, NumPy, scikit-learn, etc.)
*Gradient boosting frameworks (XGBoost / LightGBM / CatBoost)
*Experience working with LLMs (prompting, RAG, embeddings, evaluation)
*Ability to work across structured + unstructured data
*Strong communication skills – able to engage directly with stakeholders
Desirable
*Experience in: *Credit risk / lending / underwriting
*Financial data / loan documentation
*Deal scoring / probability of default
*Exposure to agentic workflows / LLM orchestration
