With that much experience and specialization, look for start up companies. I say that because I had the same problem and working on a per contract basis with start-up companies kept my skills sharp and pay is based on your contracted fees. I d be suspect of taking a substantial stock option however, because it may take years before they make a profit and the risk is always there for them to go out of business. If you can, get 3 to 5% in stock and the rest on a fee schedule. Focus on your expertise, don t go in with the idea that you are an employee - you are a consultant to the company and if asked, a member of their board of directors.
Require? I doubt it. Ask for that much experience? Maybe but I doubt it.
