Role Overview
We are looking for a Data Engineer with strong hands-on Snowflake experience to help build and maintain our Snowflake data warehouse. Working within our established medallion (bronze / silver / gold) architecture, you'll build and maintain automated pipelines using Streams, Tasks, and Dynamic Tables, and help produce well-modelled, BI-ready data sets. This is a hands-on engineering role with genuine scope to grow into a more senior architecture, governance, or team-lead position as our platform matures.
Key Responsibilities
- Build and maintain data pipelines and models within our Snowflake data warehouse, working within an established medallion (bronze / silver / gold) architecture.
- Develop and support automated, event-driven data pipelines using Snowflake Streams and Tasks.
- Build and maintain Dynamic Tables to simplify and automate transformation logic.
- Support the development of dimensional models (star/snowflake schemas, fact and dimension tables) to underpin analytics and BI use cases.
- Work with BI teams and business stakeholders to build data models that support dashboards and reporting tools.
- Follow, and help improve, data governance practices, including data quality checks, access control, and metadata management.
- Contribute to automation of the data platform, including pipeline testing, monitoring, and alerting.
- Monitor Snowflake performance and cost, flagging optimisation opportunities such as warehouse sizing, clustering, and query tuning.
- Collaborate with data analysts, software engineers, and product teams to translate requirements into working data solutions.
- Contribute to the growing use of Snowflake features such as Semantic Views, under guidance, as our platform and governance practices mature.
