She will be working with Musk and Ramaswamy on making the government less efficent, sorry more efficient.
Among the steps they appear to be working on is one where they will suspend payments, on a large scale basis, while they conduct a massive audit. They are going to use "advanced technology" to look for waste.
So remember when Musk decided to save money after buying Twitter by just not paying any of the bills, including rent? He's going to recommend doing that, for the entire government.
What could go wrong?
