Current job (supporting a production line as an engineer / ERP software power user) is old and little to no room for growth. I probably have about 10 hours of work a week. But I have to be at the factory for supporting the production line. Custom software co-developed with vendor (SAP) and my company allowed me to become an expert end user and trainer of the masses. I don't know a lot of the mechanics behind the scenes, but I am a power user and train regular people how to use various transactions and queries. This software is going to be replaced and now is a good time for me to move on to another job that challenges me.
Salary and benefits are the best for my area, and ideally I would find another job here in the factory but so far I have been turned down for internal interviews (2 different jobs) on account of my resume not being verbose enough. My only fear is that I would get into another job where I am not challenged enough and my motivation to produce quality work would suffer.
I have thought about enrolling in a certificate program to learn more about business analytics. Lots of companies in my area are excited about it.
I guess my question for Mustachians out there is do you recommend leaving a great paying job if you feel that you are not being challenged? Should I invest in acquiring new skills, even if it means leaving my current job for one that would pay less (initially?)?
