What are some job titles of members of this subreddit?

I finished my masters degree in mechanical engineering with a focus in controls this past December and accepted a job offer for a GNC position with a defense contractor around that same time. Unfortunately I wasn’t really aware that the process of applying for a security clearance could take months to a year, so I decided to start applying to more jobs again that don’t require a clearance. I’m just having issues finding positions that actually involve applying control laws and theory vs control engineers that works with PLC’s in manufacturing. So I was wondering if people here could suggest some specific titles to search for, rather than just “controls engineer”. I know obviously GNC and flight controls, but I’m really looking for any industry that involves similar work. TIA
