English to Spanish Tech/Engineering Mechanics / Mech Engineering

Hello. Can anybody help me with the translation into Spanish for "bencher"?

Here's some context:

This doesn’t even make sense because most of the tools we work on require multiple team members to work together. You can’t isolate a bencher by making them work alone because there are not enough tools that just one person can work on.


The other instance where they name something similar is here:
2. I am currently employed by the Company as a Benching / Hand Finisher in the Company’s Assembly Department


Thank you!
