Collaborating closely with analysts, analytics engineers, platform engineers and the wider Group Data team, you will help deliver data models that meet organisational needs while maintaining high engineering standards through documentation, code reviews and CI/CD practices. This is an excellent opportunity for a hands‑on Data Engineer who enjoys solving complex data challenges, working within a modern cloud-based technology stack, and translating business requirements into scalable and maintainable data solutions.

You will be confident implementing data quality controls, managing schema changes, and using Git‑based version control to support robust engineering practices. With a collaborative approach and strong problem‑solving skills, you will be able to translate business requirements into reliable technical solutions and work effectively with both technical and non‑technical stakeholders.
