Data Engineer

If you like building the pipelines and platforms behind the data, not just the reports, this role is for you.

A data engineer builds the systems that move, clean and store data at scale: pipelines from source systems to a warehouse, transformations in SQL and Python, and the platforms on which analysts and data scientists work. It is the backbone of every data team.
