Someone of potentially greater talent, depending on the quality of the hiring process and the offer you can make.
There is always a risk you end up with someone lesser or equal, especially if you value the institutional knowledge an existing member of the team brings (assuming you're not just starting out and there isn't any). The new person has to represent a significantly higher skill level to be equally useful in their first 6 months if they need to learn how a legacy system works first.
Another option is to replace en existing engineer with someone of greater talent.
