Second this. I worked in Sales Engineering for 5 years, ended that career selling a $25MM solution to the CEO of a fortune 100. There is no secret sauce, and it is all learnable. The key skills are interpersonal. I know its hard to do as an engineer, but most of (enterprise) sales is shutting the F up, listening, carefully listening, earning trust, and learning to navigate stakeholders and what their potential incentives are to help you.
