What you will bring • Strong hands on experience with Python and PySpark, particularly for complex data modelling and transformation • Strong SQL skills with experience building and optimising analytical and production ready data models • Proven experience delivering production data platforms and pipelines at scale, not just prototypes • Experience working with cloud based data platforms and modern engineering practices including CI CD, observability, and automated testing • A collaborative mindset where you actively share knowledge, support others, and raise engineering standards • Strong communication skills with the ability to work effectively with both technical and non-technical stakeholders

Why this team • A supportive and inclusive culture where every voice is heard and respected • Leadership that genuinely cares about representation and creating space for diverse careers in data and engineering • Clear progression pathways with options to grow into senior engineering, platform leadership, or deeper AI focused roles • Strong mentoring, knowledge sharing, and a thoughtful approach to performance, wellbeing, and work life balance
