Our Associate Data Engineers are in the formative part of their careers. Practically, their function and purpose differs little from that of our Data Engineers, save that their primary goal is to learn about—and contribute to—our existing processes.
In practical terms, an Associate Data Engineer will undertake the same tasks as a Data Engineers, save that they will have additional support from Engineers at other levels with the expectation that they will take the opportunity to learn from those around them.
