About the Role
Join London Stock Exchange Group's (LSEG) Group Investment Management Tooling and Data team to improve how we understand investment spend, portfolio performance and delivery outcomes. We build trusted reporting and reusable data foundations that support informed decisions and reduce manual reporting. We are recruiting Power BI developers and a hands-on Data, AI & Insights manager. Developers build and support reporting products. The manager combines team leadership with ownership of data architecture, design standards and testing strategy.

Power BI development responsibilities include designing, building and maintaining Power BI dashboards and semantic models, including enhancements, defect fixes and ongoing production support. You will turn ambiguous needs into requirements, prototypes and reporting; use feedback and outcome measures to improve user adoption. Develop and optimise DAX calculations, Power Query transformations and SQL Server data connections to improve model efficiency, refresh reliability and dashboard usability. Replace manual spreadsheet reporting with scalable, refreshable solutions; reconcile data, investigate quality issues and resolve root causes with data owners. Apply reusable design, access-control and testing standards; contribute to Agile delivery, peer reviews, releases and clear technical and user documentation.

Management and data architecture responsibilities include leading, coaching and managing the team, prioritising delivery and developing capability while personally contributing to design, problem-solving and delivery. Own data architecture for governed, reusable, AI-ready data foundations supporting reporting and future AI use cases. Establish design standards and testing strategy across the reporting and data portfolio; guide Agile delivery, assure quality and work with stakeholders to improve investment and transformation insights.

Work on reporting and data products used by investment and delivery leaders, with scope to improve standards, reduce manual effort and shape the team's data and AI capabilities. We welcome candidates whose strengths match either Power BI development or hands-on data leadership.
