The Geotechnical Sub Alliance (GSA) is at the forefront of the Sizewell C nuclear power station development - one of the UK’s largest and most exciting infrastructure programmes.
We’re responsible for preparing the foundations of the entire site: designing and constructing cut‑off walls, retaining structures, soil improvements and more.

What You'll Be Doing
Data Engineering & Architecture: Design, build and maintain scalable data pipelines across structured and unstructured sources, developing data lakes, warehouses and enterprise data models to support reporting and analytics.
Integration & Platform Management: Integrate datasets across multiple systems and partners, and manage cloud‑based data platforms (primarily Azure), ensuring performance, reliability and scalability.
ETL/ELT & Delivery Practices: Develop robust ETL/ELT processes and reusable components, embedding DevOps, CI/CD and automation best practices into the data engineering lifecycle.
Data Quality, Governance & Security: Ensure strong data governance, quality and security standards are applied, maintaining compliance with UK GDPR and organisational controls.
