My current place of employment does a good job around career develop. Managers
can't progress in their careers unless their direct reports verify they are helping with development, so incentives are aligned.
That said, it's still up to the employee to drive a lot of it. Nobody cares as much about your career as you.
So, expect to have to do the leg work. If your manager won't help find you projects you need for development, then you should go find them. Learn about cool projects being done in other groups, find out if they need help, then go to your manager to say "As a part of my development, I'd like to do X. Jim's department is doing X and would like me to help. I can make it fit with my current responsibilities. Is that OK?"
