A data engineer builds and runs the systems that move, store and prepare an organisation’s data, so it can be trusted for reporting, products and AI.
On a delivery team, a data engineer typically:
- builds pipelines that bring data in from applications, databases and third-party systems
- designs data warehouses and lakehouses on platforms such as Snowflake, Databricks or Microsoft Fabric
- builds streaming pipelines with tools such as Kafka, where data needs to arrive in real time
- sets up data quality checks, documentation and access controls
- prepares data for analysts, data scientists and AI teams
Data engineers build the foundations, while data scientists analyse the data and AI engineers build features on top of it. If you need either of those, see our data scientists and AI engineers. For an overview of the software, data and AI engineers we supply, see Software, Data & AI Engineers.
