• Build and refine real-time models to identify and block fraud before it impacts customers.
• Invent new detection strategies that outpace fraudsters and adapt to shifting attack vectors.
• Design and validate data-driven hypotheses to identify emerging fraud patterns, and transform them into scalable detection features and model improvements.
• Collaborate with engineers to deploy and scale models within production systems.
• Define model monitoring strategies, assess business impact, and iterate based on results.
• Investigate the latest advances in fraud analytics and applied machine learning.

Requirements

• Minimum of  7 to 8 years' experience as a Data Scientist.
• Familiarity with production deployment of machine learning models.
• Proficiency in Python and SQL.
• Strong capabilities in data manipulation and visualisation using tools such as Pandas/Polars, NumPy, and Matplotlib/Seaborn.
• Practical experience with machine learning frameworks such as scikit-learn, XGBoost/LightGBM/CatBoost.
• Solid understanding of both supervised and unsupervised learning techniques.
• Ability to communicate findings clearly with technical and non-technical stakeholders.

Desirable

• Experience within fraud detection, financial crime, trust and safety, or related domains.
• Experience working with embeddings and vector similarity search.
• Experience working in cloud environments, such as AWS, GCP, or Azure.
