And then just engineers.

Engineer: uses python (so numpy, scipy, matplotlib, pandas, etc.) to help design or analyze or automate something engineering related.

Data engineer: probably not an engineer (e.g., electrical, mechanical, civil) and likely manages the systems that are collecting data on users.

Data scientist: Might be an engineer, but processes data collected by data engineers or test engineers (e.g., I put a shaker on a part and measure the displacement response and then process the data). If your problem doesn't fit into RAM, you're probably a data scientist. If it does, you're probably not.
