I'm about to hop after being at my current company for almost 3 years. I feel I've shown my ability to be a lead engineer, but there's no room in my department for a new lead. I've also expressed the desire to manage, but talks with my manager about this have dead-ended. We are getting a new manager in my team's chain, but I was told they would be coming from outside the company. The sad part is our current lead is bad, really bad. He won't be moved or dismissed either. So despite leading several successful projects, I'll be stuck at senior. So, fuck it, I'm moving on.
