Hard to tell, I would guess most large well-established companies have situations / teams like this.

I work for a large videogame company, things are more or less the same, except we have two clear modes of operation among teams: * "production" (gameteams themselves), work in frantic mode all the time (crunch time being very common) * all other teams, work in glacial mode, technical debt is pretty high, same as your situation

When I started, it was my dream job. Years later...

Quite difficult to find a dream job and maintain that state of mind for long.

I would suggest you speak to your manager(s) and find / create some new projects, be creative and proactive.

Or, your current job may not really make you happy and you'll need to find something else to do.
