I have a Mech Eng degree, as do a lot of colleagues, customers and suppliers. I work in the automotive industry, and there are tons of jobs in ME, or systems/validation/calibration, and CAD. If you're at least competent with EE or software, you can get into software modeling using MATLAB/Simulink, autonomous vehicles at systems level, controls or validation.

I actually do EE work because I'm pretty competent with electronics and software, so EE/SW degree is not required.

Plus you can do HVAC, power generation, mechanical components (anything physical needs to be designed and tested by someone).

Not all the good paying jobs are in silicon valley.
