I have a problem, I need to configure my SharePoint search to crawl specific users based on their job title and exclude everyone else if your Job title is anything else besides developer the crawl should skip you!
Could you explain a bit more? What do you want to achieve?
If you want to filter the results you could simply go with a modified query in the resultsource / webpart something like
