* Tech stack terribly out of date. Refuse to use modern tools, frameworks, and development practices in favor of in-house tools that are just awful.
* Painful and archaic software development process. If you want to work somewhere agile run far, far, away!
* Practically no automated testing or CI/CD.
* The experience you gain will have little relevance outside of other large defense contractors.
* There is a good chance you will spend more time dealing with bureaucracy and red tape, writing emails, and dealing with terrible issue tracking tools than actual writing software.
* Software Engineers end up doing more System Engineering than the actual System Engineers.
* IT and DevOps support for software is practically non existent. Current "security" measures make life hell for developers.
* Good Software Engineers either end up leaving or going into management. There are little incentives to stay on the technical route compared to other companies.
* Your pay will most likely slightly below average and way below some of the big tech companies.
* Upper management is oblivious to all of the above.
