Senior Data Engineer

About the role

We’re looking for a strategic and technical leader to shape and deliver our next-generation data platform across Microsoft Fabric and GCP.

In this role, you’ll own the architecture of a scalable, secure, and cost-efficient data ecosystem, playing a key part in bridging Data, IT Security, and Business Strategy. You’ll lead the move away from legacy systems, embedding a modern lakehouse approach and ensuring our data operations are production-ready, governed, and built to scale.

You will:

• Design and implement a robust medallion (Bronze/Silver/Gold) architecture across Fabric and GCP
• Lead the migration from legacy platforms into a modern, cloud-native ecosystem
• Partner closely with IT and Security to embed Security by Design and meet enterprise standards
• Drive FinOps and cost optimisation, targeting a 15–20% reduction in cloud spend
• Establish strong data governance, including lineage, cataloguing, and eliminating shadow IT
• Set engineering standards across CI/CD, version control, and documentation
• Oversee pipeline orchestration (ETL/ELT) to ensure reliable, high-performing data flows
• Work cross-functionally with Finance, Data Science, and Architecture teams to deliver high-quality, trusted datasets

Success in this role will be measured through platform reliability, cost efficiency, successful migration milestones, and full alignment with security and governance standards.

About You

You’re a technically strong data leader who combines architectural expertise with commercial awareness and the ability to influence at all levels.

You’ll bring:

• Proven experience designing enterprise-scale data platforms across Microsoft Fabric and GCP
• Strong programming skills in Python and SQL, with experience building scalable, reusable frameworks
• Deep understanding of lakehouse and medallion architectures
• Experience with data pipeline tools (e.g. DataFactory, Dataflow/Apache Beam) and workflow orchestration
• A track record of delivering cloud cost optimisation (FinOps) and managing large-scale data environments
• Strong knowledge of data governance, data lineage, and cataloguing tools
• Solid understanding of IT security principles (IAM, network controls, secure architecture)
• Experience leading large-scale migrations from legacy systems to cloud platforms
• The ability to translate complex technical challenges into clear, business-focused insights
• A passion for raising engineering standards and mentoring others
• Experience with GA4 data modelling or supporting MLOps environments (e.g. Vertex AI) would be a bonus.
