I assume you’ve researched it and found that a job similar to your husband’s current one exists at banks operating in San Diego. In other words, are you sure that there is a counterpart position at a bank here in San Diego? Frequently, product management is done at a corporate or headquarters location, but maybe there’s a good VP level product position at midsize or smaller local banks here in SD that he’d be happy with?
The reason I ask is that I know from personal experience that a similar position to the one I had in NYC (sr mgmt in sales/mktg for a healthcare company) does not exist here even though there are similar companies. In moving to the west coast, I found that there would only be a counterpart position in either the LA or San Fran locatons of similar companies, but definitely not in San Diego.
