I did an interview with these folks about a year and a half ago—if you can make the pay and location work it seems like a great way to do socially meaningful work.
I sadly had to pass—I couldn’t make the salary or move work with health issues in the family—but the interview process was very open and the interviewers I spoke with were fantastic.
As I gathered these folks are effectively a floating software team that partners with other governmental organizations to fix problems that benefit from their skill sets. The last project I’m aware of was them revamping systems to allow veterans to more easily receive health care.
Good luck to them and whoever applies, we need more places like the USDS.
