I've been at Google for 2+ years and am pretty happy with the salary/benefits, but I'm really strating to question the overall direction of the company. It's not clear to me that Google is still innovative like it used to be. I'm a bit torn because I don't want to be cavalier and forego the opportunity that was given to me, but it seems like a lot of smaller companies are doing much more interesting work. How do I know when it's time to leave? What sort of criteria should I be looking for in other companies? I've always been interested in aerospace but most of those companies (SpaceX, etc) seem like a stretch.
(Note, I'm new here, let me know if there's anything I can do better when writing textposts)
Edit: It seems like maybe my particular role isn't that interesting. Which orgs within google are good to work for?
