Job Summary

This is a senior technical leadership role at the heart of one of the most significant data transformation programmes in UK government. You will join a strategic engagement delivering a cloud-native data lakehouse on Microsoft Azure Fabric, supporting data-driven decision making for over 22 million citizens.

As a Lead Data Engineer (internally Manager-grade), you will provide technical leadership across the data engineering function, setting engineering standards, defining design patterns, and ensuring the successful delivery of complex Azure Fabric data solutions.

  • Design, build, and oversee the delivery of complex, high-volume data pipelines using Microsoft Fabric (Data Factory, Dataflows Gen2, Fabric Notebooks) and Azure Data Factory.
  • Own the design and implementation of Silver and Gold lakehouse layers using Delta Lake, OneLake, Apache Spark, and Fabric-native capabilities.
  • Define and implement data transformation frameworks using PySpark, Python, SQL, and Fabric Notebooks, ensuring scalability, performance, and maintainability.
  • Drive data governance, metadata management, lineage, and data quality standards using Microsoft Purview.
  • Conduct architecture reviews, code reviews, and engineering assurance activities across the programme.
  • Collaborate closely with Technical Architects, Infrastructure Engineers, DevOps teams, and Delivery Leads to support CI/CD automation and platform maturity.
  • Represent Data Engineering in governance forums, including Digital Design Authority reviews, security assessments, and programme assurance activities.
  • Support knowledge transfer, documentation, and capability building activities to enable long-term client ownership and operational support.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
