Government jobs for instance (if you live in a country where that is an option). Medical profession would also be immune for some time but med school is too hard of a switch in terms of time.
What makes medical profession immune? I see this area as ripe for AI disruption. Analyzing symptoms and providing suggested medicine, tailoring dosage based on your individual vitals, analyzing data/imagery to diagnose you with diseases, all kinds of automation and speed ups for processing patient data, etc.
The same thing that has prevented self driving cars from taking the roads, i.e. that errors can be fatal. That and doctors are better unionised and won't easily let a machine practice medicine. There are all kinds of laws which necessitate the presence of a licensed medical professional in various steps of treatment. Software has neither of these cushions.
