How to ask for advice regarding a position?
I would keep it simple. Typically at this stage I have asked questions like “Are there sub fields that the department is particularly interested in hiring for?” “What courses are you hoping this position would cover?” Or the fallback/generic options “Is there anything beyond what is in the job description that I need to keep in mind when applying?” And “What aspects of my CV do you recommend I stress in my application?”

The goal is to use the conversation to introduce yourself and to tailor your application.
