Kosmos is a game company and a market leader in publishing social casual games. Our products (Solitaire Social, Mahjong Social, Yatzy Social, and others) are among the Top Grossing Facebook Instant Games.
We are actively expanding our team and investing heavily in R&D, testing new game prototypes, genres, and growth approaches.
We are looking for a Senior User Acquisition Manager to join our R&D team and become the key expert in launching and scaling new mobile and web games — from early tests to full-scale growth.
Responsibilities:
- Develop launch strategies for new prototypes and soft-launch projects, from zero to scale
- Design and run creative and marketing tests: hypotheses, methodology, analysis, interpretation of results, and insights
- Find non-standard scaling opportunities: new targeting options, audiences, segmentation approaches, and early growth signals
- Define when, how, and for what purpose to launch campaigns at different stages of a project’s lifecycle; plan budgets and control spend
- Provide expertise on growth strategy: what drives project growth and which metrics are critical at each stage
- Work closely with R&D and Operations leads, and collaborate with product producers
What we’re looking for:
- Senior-level experience in mobile UA with strong hands-on expertise in Meta Ads, AppLovin, Unity, and other channels; deep understanding of channel specifics and algorithms
- Proven experience successfully launching new mobile games in recent years (soft launches, MVPs, prototypes)
- Excellent understanding of the current mobile market: creative trends, testing approaches, channels, what works now — and what doesn’t
- Strong analytical background: unit economics, cohorts, LTV, early metrics, and the ability to make decisions with incomplete data
- Proactive mindset: you don’t wait for detailed briefs, you propose ideas, defend your point of view with arguments, and influence outcomes
Nice to have:
- Experience working with R&D projects and scaling them from scratch
- Experience with traffic acquisition for web-based projects
- Experience finding and scaling non-standard targeting strategies or creative angles
- Deep understanding of and experience with casual / social / board game genres
What we offer:
- Work on new mobile games where your decisions directly impact the fate of the project
- High level of autonomy and trust — we value expertise over checklist execution
- Strong team of producers, analysts, creatives, and UA specialists with proven launch and scaling experience
- Focus on experimentation and growth, not bureaucracy or reporting for reporting’s sake
- Remote work, flexible schedule, and competitive performance-based compensation
