"Creative Ops" is a term used to describe the development or improvement of systems and processes that support a creative team. Here's how an article from Bynder explains creative operations: 

“It involves looking at the creative process like a supply chain and figuring out where to optimize each step to produce more with the same (or fewer) number of people,”

The creative operations role is similar to an operations role in any business or industry, but it's focused on unique challenges that marketing and creative agencies face. The best fit for this role is an operations specialist with experience in both the creative and organizational aspects of an agency or in-house creative team.
