Data Engineer - Senior Consultant

Ready to build data platforms, not just pipelines? At Opencast, we believe great data engineering is about more than moving and transforming data. It's about creating reliable, scalable foundations that help organisations make better decisions and deliver better services. Our consultants tackle complex engineering challenges across integration, migration, modelling and platform design, working with Microsoft Fabric, Azure and modern data technologies. We value engineering craft, thoughtful problem-solving and building solutions that are simple, robust and built to last. As our data engineering capability continues to grow, you'll have the opportunity to influence its direction through delivery, mentoring, recruitment and technical leadership. If you're looking for a role where you can shape both solutions and the capability around them, we'd love to hear from you. The role Opencast data engineers help organisations transform how they manage, use and learn from data. The work ranges from building modern lakehouse and warehouse platforms in Microsoft Fabric to modernising legacy environments, migrating complex workloads and improving the quality, governance and reliability of critical data services. This role offers the opportunity to work across the full data lifecycle, combining platform design, engineering, integration and optimisation. Expect to work with structured, semi-structured and unstructured data, building batch and near real-time data pipelines that underpin critical business and public services. You'll collaborate with architects, analysts, software engineers and client teams to solve complex challenges and influence technical direction. The role also offers opportunities to contribute beyond delivery through mentoring, recruitment, community building and helping to define engineering standards and best practice as our capability continues to grow.
