Pros
Variety of military specific projects. Important mission to serve the people who defend the USA. Work 8 hours every day, not forced to work any more than that.
Cons
No bonuses. No salary increases for getting your PE license. Organization has struggled for years with budget cuts. Good engineers are held back by the red tape in the system, bad engineers are here because they can’t make it in the private sector and whoever is left is waiting to float on the gov’t employees’ retirement system in X amount of years. It's an "all about me" company. Blatant mistakes are made and no one cares. Getting someone fired for poor performance is impossible. Government criteria is always changing, especially every 2 years when new military management takes over. You are required to do things that don't make any bit of sense just so someone can check a box on some form.
