Job Description

We are undertaking a strategic migration of our reporting and analytics estate from SSRS to a modern cloud data platform (Snowflake). This role will support the design and delivery of that transformation—establishing best-in-class practices while remaining hands-on in building models, pipelines, and reporting layers.

You will play a critical role in not just migrating existing assets, but improving how we model, govern, and deliver data across the organisation.

Hands-On Delivery

• 
  
• Build and optimise data models, transformations, and reporting datasets

Write high-quality, performant SQL in Snowflake

Develop reusable data assets for downstream reporting and analytics

Troubleshoot and resolve data quality or performance issues

Improve the Reporting & Analytics Layer

Stakeholder Collaboration

• 
  
• Work closely with business stakeholders to understand reporting needs

Translate requirements into robust, scalable data solutions

Challenge and refine requirements where needed to improve outcomes

Essential

• 
  
• Strong SQL expertise (advanced level)

Proven experience working with Snowflake (or similar cloud data warehouse)

Experience migrating from legacy BI/reporting tools (e.g. SSRS, Cognos, Business Objects)

Strong data modelling experience (dimensional modelling, star schemas, etc.)

Experience building transformation layers in ELT environments

Track record of delivering in hands-on roles (not purely architectural)

Highly Desirable

• 
  
• Experience with dbt or similar transformation frameworks

Exposure to CI/CD in data environments

Experience rationalising large, complex reporting estates
