yes, this is possible but not out of the box. See sscit.org as an example. That was custom developed for them, but I can sell to you as is which includes installation and configuration for a reasonable fee.
It is the “Find A Therapist” search. The top three options are just category parents. It also includes a zipcode radius and keyword search fields. The zip code radius search feature can be disabled and the number of category parent drop downs are configurable. So you could have Industry, Roles, Capabilities and Availability drop downs. The way the category filters work is that an entry would have to assigned to each of the selected categories to be returned as a result. Hope that make sense.
Let me know if you are interested or not.
