• Investigate anomalies, quantify their impact on pricing and trading decisions, and communicate findings through written analyses and design documents.


• Refactor and generalise methods as new asset classes and regions expose edge cases.

Historical Datasets

• Ingest, assess, clean and maintain historical data from various external sources by designing and owning automated pipelines for corrections


• Engage researchers and traders directly on data trust, methodology, and trade-offs.


• Coordinate across curators, quantitative researchers, and developers for each dataset.

• Strong Python including the statistical libraries used for time-series analysis and surface fitting.


• Comfortable moving between interactive analysis and production code.


• A self-starter who finds the work that must be done, and does it without direction
