My advice: don't look at "big" companies. They optimize to avoid hiring the "wrong" person, which means to hire only people that come in with the exact set of skills they should be training for but won't. They won't value any of the incredibly valuable skills you've developed.

Instead, look at mid stage startups. But, find them through your connections and not by applying through job boards. People at those startups will get the value of what you've been doing. Shipping and getting harsh customer feedback is something you can't get in school and something people in big companies generally don't care about, which is why those companies can't innovate, despite hiring Chief Innovation Officers at 7 figure salaries.

Nothing wrong with wanting financial stability after seven long years. But if you go to a big company, practice your algorithm skills above all else and minimize talking about your startup experience. Sadly, it'll be either ignored because they won't understand it or they will bury it because it reminds them how they can't be innovative in their environment.
