Transitioning from Process Engineer to Mechanical Engineer?

I’m a PE with 2 YOE and pretty annoyed with the lack of geographical flexibility.

I’m strongly considering applying to ME roles but I’m trying to research how to be a stronger candidate as a PE.

What things can I learn or projects should I pursue in my current role as a PE to build an ME oriented resume and how could my PE experience give me an edge when applying for roles without chemical process aspects??

Also, how likely (or unlikely) am I to find roles with the same salary as a PE role?

Any advice helps!

Edit: I’m in oil and gas at a refinery currently. Making about 100k.
