Ha, I did maths at uni and when I first graduated, the role you described was basically my dream job.

What you call the title is up to you, “data scientist” will probably net you a lot of people who mostly want to build machine-learning models, maybe “applied statistician” or “data analyst” is a better bet? Hiring out of a local uni is possibly also a decent choice if you can deal with having to bring some maths/stats grads’ business knowledge up to scratch.
