Our objective is to reshape the value chain for our Members and Insurers using data driven insights. Our success will be based on the value data creates for our Members, risk capital providers, other suppliers and ourselves.

This role is part of a newly created and fast-growing division. The Data Office combines 3 teams;
Data Products, Data Quality and Data Management. Today, the Data Quality team consists of the Data Quality Lead and a Data Quality Support Analyst.

The Data Quality Rules Analyst is responsible for front-line ownership of the validation lifecycle, translating Data Quality intent and standards into clear, consistent, and scalable deterministic controls across ingestion, data products, and systems.

The role focuses on rule specification, catalogue governance, control behaviour, and tuning - ensuring that large volumes of data quality controls are well-structured, interpretable, and maintainable as the platform scales.

• Act as the first point of contact for:
  • New validation requests
  • Validation support requests (e.g. overrides, unexpected behaviour, suspected defects)
• Clarify intent, scope, expected behaviour and enforcement with Data Owners and Product.
• Determine whether requests can be handled within existing standards or require escalation.
• Escalate to the Data Quality Lead only where intent, appetite or priority is unclear or challenged.

• Translate validation requirements into clear, build-ready rule specifications, including:
  • rule intent and business description
  • severity and enforcement level
  • thresholds and tolerances
  • expected behaviour and override guidance
• Define deterministic data quality controls across:
  • ingestion validations
  • data product and cross-system controls
  • system- and application-level checks
• Ensure rules are unambiguous, testable, and monitorable, resolving specification-level ambiguity independently where possible.

• Own and maintain the validation catalogue content as a governed artefact, including:
  • rule metadata and descriptions
  • ownership mapping
  • lifecycle status (proposed, active, noisy, deprecated)
  • linkage to datasets and Atlan metadata
• Ensure catalogue hygiene and consistency as rule volumes scale.
• Rationalise validation inventories by:
  • identifying duplicate or overlapping rules
  • consolidating low-value checks
  • recommending retirement of obsolete or ineffective controls

• Monitor rule behaviour, including:
  • failure rates
  • override frequency
  • noise patterns
• Interpret control behaviour and form hypotheses about root cause.
• Propose bounded refinements to thresholds or logic where evidence is clear.
• Escalate to the Data Quality Lead where changes affect agreed Data Quality appetite or enforcement posture.

• Perform first-pass interpretation of anomalies and outliers.
• Analyse data and control behaviour to support Root Cause Analysis (RCA).
• Provide evidence-based recommendations to inform DQ Lead decisions.
• Support Data Owners and Product during RCA with technical and analytical insight.

• 3–6 years’ experience in data quality, data governance, analytics engineering, or data operations roles.
• Experience working with large, complex datasets with high volumes of data quality validations.
• Strong analytical mindset, able to interpret data behaviour, trends, distributions, outliers and cross-dataset consistency.
• Proven experience interpreting data quality issues at scale and forming evidence-based recommendations on…
