What are critical traits/skills of a successful data engineer?

I’m a researcher at WhoCo, a new hiring platform that aims to harness the power of data to better match candidates with roles that make them happy and successful. Our data-driven approach to hiring starts with a deep understanding of different job roles, so I’m currently looking for input from data engineers to understand what skills and traits are most critical to the job.

Would love feedback from experts in this community either here or in our brief survey (respondents will be compensated with a $15 Amazon gift card).
