Job Description

🚀 The Job Mission

The Data Engineer is responsible for designing, building, testing, and operating robust data products that underpin Assystem’s analytics and reporting capability. Working as part of a multidisciplinary Information Management Pod, the role translates business and architectural designs into scalable, secure, and maintainable data solutions.

The Data Engineer works closely with Performance Analysts and Data Architects to deliver high-quality data pipelines and products that enable trusted insight and decision-making across major nuclear programmes.

🔧 Key Responsibilities

Review business objectives, requirements, and functional designs to assess feasibility and define appropriate technical implementation approaches
Design and engineer data products and services that integrate seamlessly with business systems and processes, aligned to architectural standards
Develop data products using Databricks, Power BI, and other appropriate technologies, applying robust, scalable, and maintainable engineering practices
Build and maintain ingestion, transformation, and load routines to support the organisation’s analytics platform
Test data products to ensure they meet functional, quality, performance, and security requirements

🧭 Contextual Information

The Data Engineer operates within an Information Management Pod, delivering technical solutions based on architectures defined by the Data Architect and requirements captured by the Performance Analyst. The role is fundamental to ensuring that analytics platforms are supported by reliable, well-engineered data pipelines.

All activities are governed by the Information Design Authority (IDA) process, which ensures consistency between requirements, architecture, and technical delivery. Any deviations identified during development or operation must be formally captured and managed through the IDA governance framework.

This role suits an engineer who enjoys working in regulated, safety-critical environments and who can balance technical excellence with strong collaboration across business and delivery teams.
