Job Description
Job Summary
As a Senior Principal Data Analytics Engineer at BAE Systems, you will occupy a Mission Critical role at the intersection of software engineering, data analytics, and business intelligence. You will be responsible for supporting and implementing the technical vision for how we transform raw data into actionable insights, moving beyond simple pipelines to build sophisticated, production-grade analytics layers.
You will lead the transition toward a modern, self-hosted analytics infrastructure, ensuring that our data is not only accessible but also high-quality, governed, and ready for high-stakes decision-making. You will ensure that our data architecture adheres to stringent security protocols and regulatory requirements with a secure-by-design approach to data democratization.

Data Governance and Lineage: Establish and enforce strict data lineage and cataloging standards to ensure auditability and traceability of mission-critical KPIs.
Strategy & Architecture: Collaborate with leadership to develop a comprehensive data strategy that balances technical debt with the rapid delivery of analytic value. Architect and deploy data tooling within secure, air-gapped, or hybrid-cloud environments, ensuring seamless updates and stability without constant external connectivity.
Performance Optimization: Tune complex SQL queries and optimize data structures to handle large-scale datasets while maintaining cost-efficiency and performance. Optimize the ingestion and transformation of high-velocity telemetry or sensor data, bridging the gap between raw engineering data and executive business intelligence.
Cross-Functional Leadership: Partner with Data Scientists and Business Analysts to understand their requirements and provide the "clean room" data environments they need to succeed.
Mentorship & Standards: Serve as the technical authority for the analytics engineering team, establishing standards for Python-based automation and SQL documentation.
