I'm a software developer with close to 6 years of experience.
I switched jobs because the previous one (big corporation) had become unchallenging, stale, and the manager was unable (or not really willing) to work out any satisfying solution. My new job seemed very good on paper and the interview was one of the most pleasant I've ever participated in.
A few days before I started I was asked whether I would be keen to work in a technology (not permanently or in full capacity) that is completely unrelated to my main experience as they're looking to strengthen one of the teams. Since that technology was something I'm not really interested in working, especially in the long-run, and that technology was not even mentioned in the job offer, I answered that I'm open to it, but on the condition that it's not full capacity and only temporary. It seems they took that as a solid yes.
Right of the bat it turned out to be full-time and it's obvious it is not meant to be temporary. I was put in the team with 2 other very senior devs who seem to be happy with the situation. Everyone seem satisfied with my performance, expect me - I don't feel challenged (to be honest the job is boring) and I never wanted (nor agreed) to be put in this kind of project.
On one hand, I feel cheated and I'd like to be moved to a different team that does the kind of work I actually interviewed for and am interested in. On the other hand, I was put there only because I agreed so they think it's OK - especially because I quickly caught up and seem engaged (my manager's words).
The problem is that the management knows that nobody would agree to do this full-time if asked openly because they did (internally) and every single developer refused and they're happy I didn't. But I didn't, I just vaguely said I'm open to it and on conditions.
I'm still on my probation. How do I communicate I don't like the situation and would like to be moved to different team? Even though I know the slots (for teams in my city) are all already filled so there's not really any place to go to and the team I'd leave would be severely under-manned? Should I wait till after probation? I'm starting to feel like everyone is starting to notice I'm not really content with the situation.
