The role is heavily focused on
BAU data provisioning with end‑to‑end ownership of data onboarding, issue investigation and resolution, and continuous improvement, operating within an

The successful candidate will be
hands‑on, proactive, and accountable, with strong

SQL skills, and the ability to decompose complex business logic, understand existing technical implementations, and work closely with business stakeholders and engineering teams to ensure the reliable, high‑quality delivery of data products.

-
Work closely with data engineering and technology teams to analyze existing data logic, review SQL and code, and validate that implementations align with business intent.
-
Proactively monitor and assess data quality, identify issues early, and drive resolution through to completion rather than simple escalation.
-
Support Agile delivery by contributing to backlog refinement, sprint planning, story breakdown, acceptance criteria, and release readiness.
-
Collaborate with Front Office, Risk, Operations, and downstream consumers to clarify requirements, resolve data questions, and ensure shared understanding of outputs and impacts.
-
Ensure data solutions meet production‑grade standards, including stability, accuracy, traceability, auditability, and operational resilience.
-
Continuously improve BAU processes, controls, and documentation, reducing operational risk and improving transparency and efficiency.
-
Proactively identify opportunities for process optimisation, automation, and improved data controls, incorporating best practices across financial services data delivery.
