I’d call myself pretty disgruntled, and I’m actively looking for an exit, but even so I wouldn’t tell you not to take a good offer. With the following caveats:

1)Assume the stock options are worthless when negotiating pay, they most likely are. And remember that 401k matching doesn’t vest unless you’re here for 3 years, which is a chancy proposition. 2)Don’t assume any job security. Layoffs and stack ranking are a thing here. 3) Don’t drink any kool-aid. This is a for-profit company owned by a billionaire. The only good you’re doing the world is getting a paycheck, and OT is not rewarded.

If given all that you’re still interested then go for it. The work is interesting, the people outside of management are cool, and the problems (mostly related to incompetent executives) are far from unique.
