silicon valley companies

I want to move to SF from Seattle, for my BF. I’m level 60 at MSFT (one level below SD2). Can I get a SD2 role if I interview for another company outside? how do the levels work? I was thinking of applying to Google, Fb, Lyft, Airbnb, Pinterest, Stripe, Square, Asana, Rohinhood, Rubrick. Are there other companies with great work culture and good diversity?
