Pros
It's far from perfect, but if you're dropped on the right team, this can be a great place to work. The tech stack is legacy, but evolving. The product is a core requirement to many companies, giving stability to the company and those performing well inside it.
Cons
Management pushed an "accomplishment based reviews" system which just means you have to track everything you've done in a quarter and write that back to your manager for them write "+1" or feed into an LLM and get your token cost of living raise. The pay is not great if you are not constantly jockeying for raises/promotions. They've been pushing India and Canada hires hard, leaving teams with no managers, or no ICs to work on their FedRAMP infrastructure. They love building their own software - which is a con because FOSS and paid services accomplish the job way better, such as their self-built deployment and CI/CD systems, and costs dozens of engineers and SREs to run them.
