Pros
Up to 5% of your salary can be used to buy Saab stock, Saab will match this investment if you have stayed with them for 3 years after each monthly purchase. Seemingly at random, but a couple of times per year there are free cakes or sandwiches. You get to work on some cool things.
Cons
The company manages to survive despite terrible mismanagement on all levels thanks to a few very talented people who like working on fighters. Management does not understand what the people below them actually do (Most of them are external hires that leave within 1-2 years), and does little to try to solve the problems reported to them. There is a rather sickening obsession among the decision makers with promising unrealistic deadlines to the customers for every iteration and refusing to accept any of the negative feedback they receive about it, so the organization is constantly in a manufactured emergency over being "late", and developers are required to put in a lot of overtime to "help" reduce the delay (Which it arguably fails to do, as people make more mistakes when they are tired). Senior engineers are replaced with junior developers that are not expected to improve themselves, the remaining senior engineers are required to pick up the slack, causing them to burn out and leave, and over time the organization is turning into a less and less desirable place to work at. I believe Saab averages about 10% below market average for salaries and are not concerned with improving this.
