It's a Government Contractor - Anonymous employee CSSI, Inc. Employee Review

They have great training and sales management

There are no cons that I could find

Friendly co-workers, fair pay, interesting work, challenging projects.

Artificial restrictions on hours in accordance with Musk's mandates. Gov't is very, very cheap about buying software tools with support, which makes development dependent on open-source software and a lot of guesswork. Workflow pace can be glacial. Some lousy project leaders.
