Tech company or some other sector, the main goal of any business amounts to making money. That may involve working on "pure tech" however defined, but it will also necessarily require implementing solutions to business problems. Some of those problems will look more interesting and challenging than others.

Where in the organization you might find more satisfying work comes down the organization and what you find interesting. I doubt it has much to do with job titles, though if you have to spend a lot of time managing other people and going to meetings that won't feel like working on "pure tech."
