FULL_TIME

You should be equally comfortable discussing system architecture at a whiteboard, reviewing a complicated SolidWorks assembly, selecting a servo or bearing, evaluating a tolerance stack, troubleshooting a machine on the shop floor, mentoring another engineer, or helping a customer turn an ambiguous problem into a practical engineering solution. Most importantly, you must have strong engineering judgment: the ability to make good decisions when there is no obvious textbook answer, recognize problems before they become expensive, and distinguish between situations that require rigorous analysis and those best solved with a simple, practical approach.
