A junior engineer's focus should not be to deliver the work that is important. The business impact is the problem and responsibility of management, an engineer should do engineering and not be asked to take business responsibilities. If you design a new car engine, the sales volume and market strategy is none of your business and it is way above your pay grade. A junior engineer is the one that does what is asked to do, in the best way possible. A senior engineer is at the border to business impact, maybe, but even then the lead engineer for the rocket engines at SpaceX is not responsible of the business impact of the company.
But some bad people are trying to push more and more responsibilities to people that should focus on their domain. I also see now a push on low level engineering managers to do "organizational work" that usually does not have any meaningful impact and nobody cares about, just to be a differentiator for a promotion to the next level of even more meaningless work. Leave the junior engineers alone.
