Principal Data Engineer

Role Overview

Reporting to the Data & Analytics Lead, the Principal Data Engineer is a hands-on role, combining the building and optimisation of production data pipelines with the technical leadership needed to raise engineering standards and develop the people around them. The role functions as a key interface between a) business stakeholders and department heads, b) the wider data and analytics team, and c) owners of source systems and data in Finance and IT.

Key Responsibilities

• Designing and building robust, production-grade data pipelines on Databricks, making appropriate use of current platform capabilities such as Spark Declarative Pipelines (SDP)
• Working “under the hood” to optimise the platform for performance and cost — tuning compute, jobs and queries, managing storage and table layout, and keeping platform spend under control
• Defining and maintaining consistent business metrics and a semantic layer (for example, using Metric Views) so reporting is built on trusted, reusable definitions
• Integrating data from core business systems, including SAP S/4HANA, and other sources, using tools such as Fivetran (both SaaS connectors and HVR)
• Setting and upholding engineering standards across the team — code quality, testing, documentation, CI/CD and data governance
• Coaching and mentoring junior and mid-level engineers, reviewing their work and helping them develop
• Partnering with business stakeholders to understand their needs, shape practical solutions and ensure the platform delivers genuine value
• Engaging data owners in Finance and IT to ensure data is well understood, valid and fit for purpose, and initiating data quality improvements where required
