At Tappx, we believe the best ideas come from the most diverse minds. We are committed to building a team where different backgrounds, perspectives, and experiences are not just welcomed — they are essential. We foster an inclusive, respectful, and psychologically safe environment where everyone can do their best work and grow as a professional. We take ethics seriously: in how we build our technology, how we treat our people, and how we show up in the industry. Because doing things right and doing things well are not in conflict — they go hand in hand.

We are looking for if you have:

• 3+ years of hands-on experience in programmatic media buying or performance marketing within an AdTech company or media agency.
• Campaign Track Record: Proven experience running Mobile In-App and Web User Acquisition campaigns is highly valued; however, strong programmatic buying experience across other verticals (e.g., retargeting or web performance) is equally welcome, provided key concepts translate smoothly to an in-app environment.
• Relevant industry certifications or completed training in digital advertising/programmatic media buying are considered a plus.
• Fluency in English (both spoken and written) with the confidence to communicate, share ideas, and work closely within an international team.

Knowledge:

• Tech Stack & Tooling: Direct hands-on experience operating DSPs and programmatic ad exchanges (familiarity with Kayzen, Mintegral, Moloco, Unity, Smadex, or similar is a strong plus). Proficiency with MMPs, specifically AppsFlyer and Adjust. Advanced command of Google Sheets/Excel for campaign analysis; familiarity with ad servers, tracking platforms, or BI tools like Tableau is a plus.
• Mindset & Ownership: Strong analytical mindset, commercial curiosity, proactive drive, and solid project ownership.
