Purpose of the role:
Review, validate, and assure venue data onboarding for market abuse trade surveillance, ensuring data quality, accurate mappings, transformation logic, and business rules. Use SQL and/or Python to perform pre- and post-development testing, providing evidence-based assurance that solutions meet surveillance requirements and support SME approval.

What you'll do:

• Conduct assurance testing of developed solutions, investigate defects, validate fixes and confirm outputs align with agreed requirements and source data.
• Document findings, maintain issue logs and collaborate with Business Analysts, Data Architects and Technology teams to resolve data quality and implementation issues.
• Validate data quality controls and reporting, ensuring completeness, accuracy and traceability of surveillance data through the SDML framework.
• Support data governance activities, including data glossary updates, impact assessments, stakeholder forums and the onboarding of new venue feeds and asset classes.

The skills you'll need:

• Strong hands-on proficiency in SQL and/or Python, with the ability to independently write queries or scripts to interrogate, validate and reconcile datasets.
• Experience analysing trade and/or order data and understanding its use in market abuse surveillance.
• Experience reviewing FSDs, business filters, source-to-target mappings, transformation logic and data quality controls.
• Experience translating documented requirements into test cases and conducting data validation, UAT or post-development assurance testing.
• Strong analytical and problem-solving skills, with attention to detail and a clear evidence-based approach.
• Ability to document findings clearly, challenge requirements constructively and work collaboratively with BAs, Technology and surveillance stakeholders.
• Knowledge of data governance principles and practices, with the ability to maintain requirements-to-test traceability.
• Ability to work independently and as part of a team.
