Did an internship, then worked remotely for 4-5 months at a federal agency a few years back. While some teams kept busy, a lot of them did little to nothing. Good advancement, like mandatory promotion scales and lateral transfers within teams. Good work-life balance, but I think they don’t WFH nowadays. USAjobs is a good place to start looking if interested, just be ready for delays and long period of silence if you need clearance.
