• Develop data models to handle enterprise‑level analytical needs
• Optimise large‑scale data processing systems for performance and cost‑efficiency
• Implement robust data quality frameworks and monitoring solutions
• Evaluate new technologies to enhance our data engineering capabilities
• Collaborate with stakeholders to translate business requirements into technical specifications
• Present technical solutions to leadership and non‑technical stakeholders
• Contribute to the development of the Methods Analytics Engineering Practice by participating in our internal community of practice

Your Impact:

• Enable business leaders to make informed decisions with confidence through timely, accurate data insights
• Establish reusable engineering standards, patterns and documentation that support quality, maintainability and repeatable Data Foundations delivery across future engagements.
• Drive adoption of modern data architectures and platforms
• Deliver seamless data solutions that enhance user experience

• Hands‑on experience profiling data quality issues, defining cleansing rules, mapping data between systems, validating reconciliation outputs and documenting exceptions for business review.
• Ability to work iteratively with architects, process owners, finance, procurement, workforce and operational stakeholders to turn ambiguous business issues into clear data analysis, engineering actions and controlled tactical fixes.
• Understanding of data ownership, stewardship, lineage, metadata, controls and data quality monitoring, with the ability to produce documentation that can be reused as part of an enduring data governance model.
• Experience implementing and advocating for test‑driven development methodologies in data pipeline workflows, including unit testing, integration testing, and data quality validation frameworks
• Proven experience leading technical aspects of data projects
• Strong data architecture and modelling skills with the ability to design scalable data solutions
