I have analogous experience working on projects/organizations that have experienced potential terminal neglect, though not at FAANGs. Probably I'd accept that your hours will be longer than acceptable, if that's a tradeoff you can handle. What you get in return is avoidance of the feeling that you spend all your time accomplishing nothing. From there, it's building relationships, documenting what gets accomplished, and trying to meet people where they are so that they can maybe get something done (and not break other things.) That's from a managing perspective, but if you are determined to not coast, that may be what you'll be doing.
