Senior Data Scientist - Contract£700-£850 per day Inside IR35 Hybrid (1 day per week London)We''re looking for a Senior Data Scientist to design and deliver advanced risk and predictive models within complex, highly regulated environments.This role sits at the intersection of analytics, risk, and decision science, focusing on building models that enable organisations to identify emerging threats, quantify risk exposure, and make informed, evidence-based decisions. You''ll work across large, complex, and often sensitive data sets to develop modelling frameworks that support real-world, high-impact outcomes.Key responsibilities:Design and develop advanced risk models, including predictive, probabilistic, and scenario-based modelling approachesApply data science techniques to risk scoring, anomaly detection, and threat assessment across complex datasetsBuild and deploy machine learning models into production, ensuring scalability and robustnessDevelop scenario simulations to model potential risks, behaviours, and outcomes under uncertaintyAnalyse patterns, trends, and outliers to identify emerging threats and risk indicatorsTranslate business and regulatory requirements into practical analytical frameworksCommunicate complex findings clearly to technical and non-technical stakeholdersEssential experience:Strong Python data science stack (pandas, NumPy, scikit-learn)Proven delivery of complex models (predictive, probabilistic, simulation-based) in real environmentsDeep experience
