Overview
We're looking for an experienced Technical Data Analyst to join our Data Technology team. This is an exciting opportunity to help shape and deliver high-quality data products that support reporting, analytics, regulatory requirements and business decision-making across our organisation.
Working at the intersection of business and technology, you'll partner with Data Engineers, Architects, Product Owners and key stakeholders to analyse complex insurance data, develop robust data models and ensure trusted datasets are delivered across our modern cloud data platform.
This role is ideal for someone who combines technical expertise with a genuine interest in solving business problems through data. You'll be comfortable working hands-on with SQL, Snowflake and dbt, while translating business requirements into scalable technical solutions.
This role is not a senior position and would suit someone looking for their next step.
