Ad Monetisation Manager (all genders)

Role Summary

You'll own ad monetization across JustPlay and Gimica Games (9-figure annual revenue) - managing waterfalls, driving ad partner relationships, and pushing ad product innovation forward. After onboarding, this isn't a support role. You'll have real ownership, autonomy, and the expectation to leverage AI to move faster than a traditional team ever could.

Responsibilities

• Own ad monetization strategy and revenue across the mobile games portfolio
• Manage bidding and waterfall configurations in MAX Mediation - experiment freely, ship fast
• Negotiate commercial deals with ad partners and resolve technical issues (SDK updates, discrepancies, creative quality)
• Build and automate ad performance reporting (eCPM, ARPDAU, IMPDAU) - use AI, scripts, whatever gets you there fastest

Collaborate cross-functionally to optimize ad product monetization

• Proactively bring new ideas - ad formats, mediation tactics, AI workflows that save the team hours
• This role isn't for you if
• You need detailed instructions for every task
• You're uncomfortable making decisions with incomplete information
• You see AI as a buzzword, not a daily tool

Job benefits

• Work-Life Balance and Flexibility: Flexible working hours and options for digital nomads, occasional office visitors, or regular office-goers
• Mental Health Support: Free personal coaching through our partner to support our team members to live fulfilled lives at home and at work
• Training & Development: A competitive personal development budget of up to 2000€/year for training, conferences, workshops, etc.
• Germany-Based Benefits: 25 vacation days, free Wellhub gold subscription, free monthly Deutschland-Ticket, and a monthly €50 tax-free internet contribution
• State-of-the-Art Equipment: Doesn’t matter if you are a MacBook or Windows user; we will provide you with the technical gear you need to succeed
• A Relocation Package: Includes visa support for those who need it
• Berlin Office Perks: Ergonomic setup, free daily lunch, and a dog-friendly environment.
• Engaging and Diverse Work Environment: Join a diverse team, with over 30 nationalities working from over 25 different locations
• Benefits may vary depending on location and contract type. Do not hesitate to ask us about more details on our benefits offer.

Requirements

• 1+ year in mobile ad monetization (or less if you learn unusually fast)
• Solid understanding of mobile gaming economics and waterfall optimization
• You dig into data obsessively but hate doing the same manual thing twice — you'd rather automate it
• You already use AI tools daily in your work, not because someone told you to
• You thrive with goals and trust, not daily task lists
• Fluent in written and spoken English
