Pluspunten
RTX has the best work-life balance of any company I've worked for, I'm technically hybrid but I only have to go onsite if I'm accessing classified information or need to get hands on hardware. It's been refreshing to work for a company that understands that forcing me to sit in a cube farm just to listen to unclassified Zoom calls isn't going to make me productive. The culture can vary program to program, but that's mitigated by how easy it is to change programs should the culture not be a good fit. This also makes it easy to pivot your career in any direction you desire.
Minpunten
The main one for me is how bad the benefits are, the health insurance is easily the worst I've ever had. Even with their "best" plan you'll still be paying $80+ out of pocket for routine doctor visits. I wish I had scrutinized this more closely when negotiating for salary. Another problem is onboarding, while corporate has made a big effort to improve new hire onboarding the experience takes a dive once you get assigned to a program. Standards vary wildly between programs, they all have their own drawing sheet formats, PowerPoint templates, & so on that any outside experience you bring is likely to be irrelevant to completing actions. This is exacerbated by the long-term employees often refusing to take the time to teach new employees these program-specific quirks. The training offered is about 50% "you'll be taught more about this on your specific program", which is more often than not a lie.
