Solutions Engineer is a pre-sales role and the role I held at F5 for a long time so I can speak to it well. It was very rewarding to meet with my customers, hear about their business challenges and present them F5 solutions that might help. This particular role is a Solutions Engineer II which is great for someone who has no or minimal experience as a vendor Sales Engineer.
I speak to it a bit further on this live stream @ 1:30
