DDS Hires a lot of motivated engineers who would be in civil service but for the $180k -> $90k paycuts and fear of bureaucratic hell. It is run by one of the ~founders of opentable who, post opentable riches, was flying on 9/11/01, decided to join the Chicago PD as a result, did west Chicago homicide until the PD discovered his past, he then stood up Chicago’s data-based policing technical approaches, and eventually the Obama admin heads about him asked him to take over DDS (iirc, +/- details there).
Cool stuff and I’d work for them in a second, probably need another few years in private sector though.
