In each review since I started at my current position, my manager has stressed that he is looking for someone to "step up and take a leadership role". I was hired just as his longest-working employee left, and was brought in as a "not-quite-senior" developer. Given this, I modified how I approached the 2 newer developers as well as the entire team in general (there are 4 of us plus the manager).
Now, people are coming to me for suggestions and hints to things, as I do have the most experience in the industry, and have a pretty extensive knowledge base. I've put several procedures in place for management of errors, code repositories, processes to deal with Help Desk issues, all with my manager's approval.
In the latest review he's back to asserting he "needs a leader". I'm not sure what else I can do to move into the role he is very obviously (to my mind) trying to shift me into. I've learned the products that I'm not versed in, I've learned new tech, I've mentored and assisted my co-workers. How can I step up, or how can I determine what he means by stepping up to be a leader?
