Marketer for testing advertising hypotheses

We are a startup in the field of voice technology with a team and we want to test several hypotheses in international markets by launching several banners with Facebook ads.
One banner will be associated with the celebrity voice changer, the other will be about changing the accent for the interlocutors.

We need a marketing specialist who will help us correctly formulate hypotheses, build a funnel, understand what kind of audience we need and launch good advertising campaigns for us for testing several hypotheses.
Main KPI: the price of click.

(!) Experience with advertising mobile applications and high-tech products is required.
