Hire the person first then ask them to design the job. What would happen. Not enough enough to topple the company. In fact given a goal to move from A to B, a time frame and a budget - most humans can act responsibly. Give them a political and physical environment where they can innovate.
Power goes with the job.
I am not advocating giving up total centralised control. Authority is needed from management. I do not endorse anarchy . The power of information technology empowers individuals to a fuller capacity. Knowledge is becoming the one critical factor of production.
