This has been my experience as well. Beyond a level an engineer creates value by being at the intersection of product/UX, business, and tech; by being able to seamlessly transition between them. As a consequence if one changes jobs say every 2-3 years (different domains) then they become generalist engineers. In my experience one has to spend 10-12 months at a company to pick up a domain by being deliberate at it. It may look like a big investment but the payoff will be significant once they have sufficient context in their head.
