We are seeking a talented and highly experienced Senior Data Scientist to join our Data Science team within the critical Risk domain. This role uniquely combines hands-on development of vital risk prevention models, contributing to the technological strategy, and driving innovation in the field of AI Agents.
Qualifications:
- 7+ years of experience as a Data Scientist, with a proven track record of applying advanced statistical and machine learning methods on real-world problems (or 3+ years with a PhD).
- Strong background and practical experience leading the end-to-end execution of complex Machine Learning projects.
- Comfort with the realities of risk modeling: highly imbalanced and adversarial data, delayed/noisy labels, and the precision-vs-recall tradeoffs of acting on legitimate users.
- Full ownership of projects from initial idea through production deployment, working closely with engineering to get there.
- Experience in Generative AI, defining, building and evaluating AI-agents and leveraging foundational language models for introducing advanced new capabilities within existing products and systems.
- Experience in working with large-scale data processing pipelines, Cloud Computing and Machine Learning Operations.
- Demonstrated habit of working with AI: actively use LLMs/agentic tooling in your day-to-day workflow, and you instinctively turn recurring problems into reusable automation.
- B.Sc in Computer Science, Software Engineering, Mathematics, Electrical, Statistics, or a related quantitative field.
Bonus points:
- Experience developing models in the Risk domain (such as Fraud Detection, Anomaly Detection, Anti-Money Laundering) or Fintech.
- M.Sc/PhD in Computer Science, Software Engineering, Mathematics, Electrical, Statistics, or a related quantitative field.
