Data is critical to our quantitative trading business.

Key Responsibilities
- Identify and resolve failures that arise from automated data-quality checks, such as erroneous prices, by cross-referencing with other sources and patching in corrected values.
- Liaise with data vendors about missing/late data, access issues, and incorrect data.
- Source and maintain metadata that underpins DSG data extracts and services, such as setting up a new Future or ETF, which requires sourcing multiple vendor codes and sanity checking the data generated before it goes into production.
