About Us
We are a technology solutions provider specialising in the public sector. Our mission is to help government organisations become truly data-driven by transforming their digital services, streamlining operational processes, improving citizen outcomes, and enhancing transparency across public services. We work closely with government bodies to design and deliver modern, secure, and scalable digital solutions that have real-world impact.
The Role
We are looking to engage a Data Engineer on a contract basis to support the delivery of high-quality digital services within the UK public sector. You will lead the design, development, and evolution of scalable data infrastructure, pipelines, and analytics platforms, working closely with our existing Data Engineers, Data Architects, Analysts and wider delivery teams to deliver high-performance data solutions.
This role requires deep knowledge of data engineering best practices and strong hands-on experience with AWS, Apache Spark, data warehousing (Redshift / Apache Iceberg), database modelling, and SQL. You will provide technical leadership across the full data engineering lifecycle, from architecture and pipeline design through to implementation, optimisation, monitoring, and data quality, while supporting engineering standards, technical decision-making, and the development of other engineers.
You will also understand the security, governance, and delivery expectations of working in central government and highly regulated environments.
