## About the Role

We're looking for someone with around three years' experience in a data, BI or Power Platform environment. This is a guide rather than a rigid requirement, we're much more interested in what you've actually built, delivered and taken ownership of.

 * Strong Power BI experience, including semantic modelling and DAX beyond the basics.
 * Confident SQL skills, including writing and optimising views and queries and understanding query performance.
 * Practical experience with at least one of Power Apps, Power Automate or API integration.
 * The ability to work end to end - taking an ambiguous business problem, understanding what is really required, building the solution and supporting it afterwards.
 * Strong communication and stakeholder-management skills, with the confidence to work directly with department heads, senior leaders and customers.
 * A naturally curious approach to data and the wider business - you're interested in understanding why something is happening, not just producing the report that was requested.
 * Good judgement around quality and delivery - knowing when something needs to be absolutely right and when a pragmatic solution is appropriate.

These aren't essential, but would be advantageous:

 * Experience with Microsoft Fabric, particularly lakehouse's, notebooks and pipelines.
 * Python experience for automation or data movement.
 * Experience implementing row-level security, particularly within multi-tenant or customer-facing reporting.
 * Experience mentoring or reviewing the work of more junior developers or analysts..

## Description

The data and technology environment is evolving, with a modern Microsoft-focused stack including:

 * Microsoft Fabric - with the ingestion layer currently being rebuilt
 * Power BI and Fabric - reporting and semantic modelling
 * Power Apps and Power Automate - business applications and workflow automation
 * APIs, Fabric notebooks and Python - integrations and data movement
 * SQL - supporting an established on-premise data estate

The team is currently being rebuilt and expanded, meaning you'll be joining early enough to have a real influence on how the function operates, the standards it sets and the solutions it delivers.
