Connecting a SQL Jobs database to a WordPress Page

I just started with a company that has a careers page which links to a separate server. I’d like to rebuild the code in our WordPress page. Ideally I do not want to use an iFrame. Are there languages supported by WordPress where I can connect to our SQL server to pull the jobs and recode just the page or do I have to import the jobs database into WordPress also?
