Pros
GDLS - robotic systems is a high-paced high-tech place for engineers to do real R&D work that means something to the average Joe Soldier. You're certainly not stovepiped into a boring day to day job. Engineers are challenged and expected to take the lead and innovate. Senior engineers and scientists are very intelligent, innovative, and ambitious. The subject matter really sells itself. Who doesn't want to build robot vehicles?
Cons
GDRS is a small subsidiary that has grown large very quickly. The tools and management structure of a large organization have not yet taken hold. There is little coherent organization. This can be very frustrating while trying to put a large, complex project together. The senior management occasionally makes commitments to keep engineers and scientists in the loop, but few initiatives have really been fruitful. Working in a community of very committed and intelligent individuals, great hard work can often be overlooked as managers and coworkers move on to the next high-paced program.
