I've gotten to know half a dozen people at USDS and I visited the offices a few years ago. Everyone I met there was the kindest, coolest kind of person you'd find in tech, and they were all there to do great work on what are usually terrible government websites. They were usually people that worked in startups and wanted to do something more meaningful with their talents.
The free COVID tests you got from USPS that all fit on a single-page form? That was USDS.
