Avoid At All Costs - System Engineer Peraton Employee Review

I have worked at Peraton on a Department of Homeland Security contract for over a year before recently quitting. During the past few months, I have seen Peraton negatively disrupt the contract that I was working on. The application I worked on continued to rapidly degrade under Peraton. At least two higher ranking Peraton employees were well aware of the application's increasing issues, yet repeatedly chose to ignore them, disrupting the DHS's ability to properly function. The two employees in question even have admin rights to the application, which they most certainly should not. I notified HR of numerous concerns while working at Peraton, and they also failed to properly address them, including a sex based discrimination complaint. They even appeared to retaliate against me for doing so. On my resignation, an HR rep even admitted to siding with the individual I reported, proving their unethical and suspicious bias. They terminated my account the next day, leaving me unable to complete the employee resignation checklist that they claimed I am required to complete. I eventually notified DHS employees of my concerns. I even notified Peraton's CEO of HR's behavior. My Peraton account was terminated before I could see a potential response to that email. Peraton is likely being investigated by the government for their suspicious behavior. I imagine DHS employees are possibly being investigated as well.
