This also has the added benefit of making a lot of money even by engineering standards in the right organization. Looks for large enterprise companies where custom demos and new customer hypercare are standard. I've been on the other side of the table a few times and often pre-sales cycles are months long and contracts start in the $2-4M range. Those are the places where sales engineers will be treated as first-class citizens and not just "hey grab one of the engineers for this sales call."
