Amazon KDP Advertising Manager

We currently have hundreds of books for sale on Amazon through KDP (print on demand books), and are looking to expand and hire a part-time/full-time KDP Ads manager. This job would require experience and examples of previous campaigns that have been managed and scaled over time. Daily spend budget per book would in the $10-$30+ range depending on results, and the daily task of the hire would be to continually create new ad campaigns and optimize them for improved conversations and success. Bonuses will be rewarded with great results.
