Job description

Our client is an established and growing business investing heavily in its data, BI and automation capability.

This is an exciting opportunity to join a small, ambitious Data & Insight team at an important stage of its development. The team owns the full data journey — from extracting information from source systems and data modelling, through to delivering meaningful insight to senior leaders, operational teams and customers.

You’ll play a key role in connecting data across different areas of the business, identifying relationships and opportunities that individual departments may not see themselves.

What you’ll be working with

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

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

The Data & Insight team is being rebuilt and expanded, so you’ll have genuine opportunity to influence how the function operates, the standards it sets and the solutions it delivers.

What we’re looking for

We’re ideally looking for someone with around 3 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 built, delivered and taken ownership of.

You’ll ideally have:

• Strong Power BI experience, including semantic modelling and DAX beyond the basics
• Confident SQL skills, including writing and optimising views and queries, with an understanding of 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 the requirement, 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 — interested in understanding why something is happening, not simply 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

It would also be advantageous to have experience with:

• Microsoft Fabric, particularly Lakehouses, Notebooks and Pipelines
• Python for automation or data movement
• Row-level security, particularly within multi-tenant or customer-facing reporting
• Mentoring or reviewing the work of more junior developers or analysts
