Currently, the CEO manages Apple Search Ads, and we have various contributors for other channels. We need one high-level operator to centralize, manage, and scale these efforts with a relentless focus on Contribution Profit.

The Ideal Profile

• Data-Obsessed: You don't make moves based on "gut feelings." You live in spreadsheets and analytics dashboards.
• High Agency: You don't wait for the CEO to tell you what to test. You come to the weekly meeting with a list of what you've already launched.
• Ukrainian Tech Expert: You understand the remote work culture and have a track record of working with international startups.
