My favorite way to handle these types of situations is to contact any lawyer you trust and ask them to recommend someone. They will not only know the correct discipline for your particular scenario, but being in the industry, they’re a better judge of quality than just picking someone randomly out of a search engine. The first time I needed a lawyer to review business paperwork, I called a local personal injury lawye…
More particularly for this question, while the state bar can be okay for referrals, you probably want someone who has worked in labor & employment law, or someone familiar with equity agreements if equity/stock is a meaningful component of the comp (look for a "startup lawyer" or "emerging companies lawyer"). Both of those will be familiar enough with the IP issues and general contract provisions. You'd probably only want an IP specialist if you're specifically licensing prior inventions (or you have IP-heavy side projects that you want to exclude).
Good luck!
