Jobs like devrel can also have a good combination of being technical and talking to people and giving presentations.
Finally roles like "Technical Account Manager" can vary really widely across companies - in some cases these are basically glorified support jobs or sales jobs where you're dealing with existing customers instead of new customers. In other places it can be more like a solutions engineer where you're implementing a customer-specific solution using your company's platform. Again, a lot of 1:1 communication with customers.
You get to build demos, and learn new technologies and never have to be responsible for production.
The earning potential can be very high, especially if your team exceeds your sales quotas.
Look for jobs like solution architect, sales engineer, customer engineer, pre-sales engineer.
It's not easy to find people who are personable but can also explain the underlying tech clearly to potential customers... and the best tech in the world isn't with a hill of beans if it isn't being used by sutomers. If your an inherently social, dependable and trustworthy person, I believe the sales part of it comes naturally.
