Matt, I've been through a remarkably similar path. I shifted back to a more technical role (from project engineer to systems engineer), and a year or so later jumped to a different company. The issues I experienced with my original employer were similar to yours. I think the change was good, and I enjoyed the more technical work I was doing, especially since it was more big picture stuff. I could've stayed on the management track back then and been happy, too. Heck, I'm back in management now and here I'll stay. Good luck with your decision.
