Background
I'm currently at a cross section in my career in a corporate. I'm almost a year working as a software engineer; in that period of time I've passed a team straining about the team's back-end and front-end technologies, fixing bugs (while getting help from the only teammate who fix bugs), some refactoring metrics, and a POC of our main project which planned for us this year. Right now, other teammates are working on tasks of the projects while I didn't get so far any task that is related to the project. All what I got is bugs, and the fact - "you're supposed to replace him and take all of the responsibilities of maintenance from him", even though I did in the past months a deep research and built a POC.
My question
How can I ask from my manager to involve me in the project, while they clearly said to me that I'm the "new guy", and somebody must to do all of this dirty work?
