Senior Business Intelligence Developer / Senior Data Engineer

The Role:

An exciting opportunity has arisen to join our Business Intelligence Systems (BIS) team at a pivotal moment in our tech journey - transitioning from legacy architectures to a modern cloud-first data ecosystem. You won't just be maintaining systems; you'll be building the future of our data infrastructure. In this role, you will utilise data, analytical, and reporting tools to develop new products, optimise existing solutions, and support our users across the business.

The BIS domain works in close collaboration with stakeholders across key Business areas such as Finance, Product, Marketing, and Contact Centre to design, build, and support the critical data solutions NEXT relies on for operational and business analysis. Our thriving department features 80+ developers, analysts, and product managers focused on value driven delivery.

As part of a product team, you will develop solutions tailored to meet business requirements, including initiatives such as cost-saving efficiencies, cyber resilience, and data security controls. Furthermore, you will support various data ingestion pathways, execute data compliance frameworks, and optimise our internal workflows to maximize process efficiency and operational stability.
