Pros
Benefits. Pay, but total compensation is heavily based on the bonus which fluctuates a lot. If you end up on a good team most people care, and want to be helpful. Some of the best people I have worked with are at ups
Cons
On call support. Getting woken in the middle of the night will happen. Even for small issues that could wait. When something isn't working even if its caused by something out of your control eg proxy, you will be required to be on the bridge. There are teams that are difficult to work with. They are dismissive of issues you experience. They will blame your application, or everything else until you prove to them its actually caused by their system. This is only getting worse. As ups tries to move to new technologies and systems app teams are required to use new services who are supported by teams that not equipped to provide help, or know how the service they support works. More contractors are being hired to do work. They do not participate in the on-call rotation, so when their code doesn't work upsers are the one who get called and have to deal with it. It also means being on call more frequently. Info sec will put in requirements, not communicate them, and the app teams are left dealing with the aftermath. Some requirements go against union rules and possibly DOT regulations. Migrations are poorly planned, and app teams are left to figure out a plan that will work. Multiple rounds of lay-offs in 2024.
