Enron was not a stain on a resume, not unless you were actually a leader involved in their troubles. I worked in banking shortly after that time, and we had some ex-Enron folks on the team. It wasn't a concern - they were hired for their skills, and any talk of Enron was more about just laughing at having to switch jobs because of it.

FAANG will likely be the same - you did your work for them, and chose to move on at some point. The flaws of their leadership don't negatively impact your tech skills.
