Data Quality & Governance Engineer

Data Quality & Governance Engineer | Challenger Bank

We are looking for a hands-on Data Quality & Governance Engineer to build and run the technical spine that underpins the Data & AI function for a fast-scaling, UK-licensed challenger bank.

This role sits at the intersection of engineering and risk. You will be responsible for building quality, metadata and lineage capabilities directly into the data platform to ensure a single, governed view of all critical assets.

You will be working closely with the Head of Data & AI and senior engineering leads. Your mission is to turn governance policy into automated patterns. Ideally looking for Collate experience for governance however experience with similar platforms (Atlan, OpenMetadata, Collibra, or Alation) is highly valued.

What you will do:

• Use SQL and Python to implement automated checks, alerts and observability for critical datasets and AI features.
• Own the technical side of the enterprise data catalogue and glossary. You will ensure that end-to-end lineage—from source to warehouse to AI model—is accurate and functional.
• Act as the bridge between technical teams and Data Stewards. You'll define Critical Data Elements (CDEs) and ensure everyone understands why specific metrics are being measured.
• Fix data issues at the source, embed controls (schema validation, PII, data contracts) into pipelines, and help evaluate/introduce new observability tooling.

What we are looking for:

• Strong hands-on Python and SQL. You should be comfortable building custom metrics and working within modern stacks (AWS, Redshift, dbt).
• You understand data lineage, ownership and stewardship. You don’t just know how to use a catalogue; you know why it’s critical for a regulated bank.
• Background in a Challenger Bank, Fintech or a similarly highly-regulated sector. You understand the pressure of getting calculations up to spec for audit and assurance.

Further information:

• London (2/ 3 days per week in-office)
• Up to £75,000 (with potential wiggle room for an advanced technical candidate)
• Outstanding benefits package on offer and will be disclosed during qualification call
