Responsibilities:

• Design, build, and sustain sophisticated, user‐centric Power BI dashboards and paginated reports that enable timely, data‐driven decisions across the People Function.
• Design and implement robust semantic models (star/snowflake) and calculation layers (DAX, measures, calculation groups) to ensure accuracy, performance, and ease of use.
• Assess and fulfil on‐demand reporting requests on People data, ensuring responsiveness, clear scoping, and reusability where appropriate.
• Lead reporting standards and run‐the‐month cadence to ensure monthly reporting is reliable, accurate, and released to the right audiences on time, every month.
• Harmonise existing dashboards and reporting, reducing redundancy, consolidating key metrics, and improving navigation and user experience.
• Influence and enable self‐service analytics, coach partners globally, promote certified datasets, and embed standard processes for insight generation and decision support.
• Act as technical lead for the BI toolkit, guiding the team on BI architecture, data modelling patterns, performance tuning, governance, and DevOps for analytics.
• Integrate Workday Reporting extracts and other HR systems data into governed data pipelines; partner with Data Engineering on data quality, lineage, and refresh reliability.
• Operate with strong governance, including row‐level security, data privacy, access controls, and clear documentation (data dictionaries, playbooks, runbooks).
• Continuously improve, supervise usage and performance, own A/B experiments on design patterns, and iterate with partners to maximise adoption and impact.

What you’ll bring:

• Strong, shown expertise in Power BI (Power Query/M, DAX, data modelling, composite models, Incremental Refresh, RLS, deployment pipelines, and governance at scale).
• Workday Reporting experience (advanced reports, calculated fields) and Alteryx (or equivalent) for data preparation highly desirable.
• Hands-on experience with people analytics platforms such as OneModel or Visier, designing, building, or maintaining dashboards and data models in these environments is a strong advantage.
• A track record in People/HR business intelligence within a complex international environment, with clarity on people metrics, definitions, and controls.
• Practical BI authoring experience, including UX for analytics, accessibility, and executive‐level storytelling that connects insights to actions.
• Project and product management capability (prioritisation, backlog management, customer engagement, iterative delivery).
• Customer focus and the ability to work optimally with diverse collaborators across functions and regions; good communication and influencing skills.
• Adaptive working style and able to move at pace when needed and pause for reflection to improve quality and sustainability.
• Resilience in a people‐centric business with evolving priorities; comfort with ambiguity and change.
• Cultural awareness and sensitivity; commitment to ethical analytics and privacy.
• Data‐led and technology‐savvy attitude, with curiosity to learn and improve the BI stack over time.
