A key part of the role is developing AI-powered risk detection capabilities, including name screening, entity resolution, network intelligence, and proactive discovery of previously unknown risk patterns.

You will partner closely with Risk Product, Engineering, Financial Crime Compliance and Risk Operations to translate complex risk problems into scalable, production-grade controls.

• Partner with Risk Product, Engineering, Financial Crime Compliance and Risk Operations to translate complex risk problems into effective, scalable production controls.

• Influence the Risk Product roadmap and raise the technical bar for Risk Data Science through technical leadership, reusable frameworks, and mentoring.

• Familiarity with modern LLM evaluation, prompt/model experimentation, retrieval quality assessment and AI observability.
