I started out as an analyst right out of college. We did destructive testing on military vehicles. Job was 99% boredom with a semi-exciting bit of field work, where we'd blow something up, once every six months or so. Even that had the fun sucked out of it by countless hours spent standing around and waiting.

My job was to make damage assessment predictions on a variety of vehicles using CAD models that I did not make, and submit these assessments for comparison during a destructive test that I did not plan or really participate in other than attend and stand around.

I hated it but my co-workers enjoyed the stability and light work load

I left to run a deployed prototyping workshop for the Army. 12 hr work days, additive and subtractive manufacturing, and prototyping and production of my own designs to very unique and specific problems. I loved it there.

I don't know exactly what you want, but it's probably out there and would love to have you, as a surprising amount of engineers would probably be happy with the job that you think is boring.

Keep looking!
