Welcome aboard! I had a not-dissimilar experience with the USGS early in my career. I started out as a contractor with the Atlantic Marine Geology branch in Woods Hole, MA. I would have loved to stay (nice people, interesting work, lived a mile from the beach, biked to work, etc.) but the USGS at that time consisted of people who had been there for decades or months. And there was not much chance of ever moving across that divide. Fortunately I found an opportunity to do cartography in a much more stable agency.
