In four of the last five jobs I have held over the last 30 years, I have been the "last resort", the one who can find a creative, elegant, cost-effective solution when everyone else is hitting dead ends or just sitting there spinning their wheels in the mud.

But people who are good problem solvers may not be good at Fermi problems.
