> Senior engineers want to learn new domains like sales, learn leadership skills, have a say in product direction ect.

Not all senior folks are interested in that stuff though. Some are more interested in picking up new tech and delivering good quality technical work than they are in going outside of tech to other parts of a business, or getting into management.

> That to me is exciting stuff

Sounds to me like you're less interested in the software creation aspects these days, which is also fine :)
