• Working knowledge of SQL (we use Postgres and Vertica);
• A data-driven mindset with strong analytical thinking and a critical approach to problem-solving.
• Proactive, self-motivated, and results-oriented.
• Strong problem-solving skills, with the ability to analyze and interpret large datasets to generate actionable insights.
• Degree in a quantitative field such as Data Science, Mathematics, Computer Science, Economics, Statistics, or a related discipline.
• Passion for games and a genuine interest in the gaming industry.

• Familiarity with basic machine learning techniques, including regression, classification, and clustering.
• Experience working in the mobile gaming industry.
• Experience designing, running, and analyzing A/B tests.

Your responsibilities

• We work end-to-end the entire journey of an analytical problem - from the business need, through analysis, to conclusions and recommendations:
• understand product and data-related needs, and effectively collect requirements, then plan the end-to-end process;
• work closely with our data engineers to design, build, and maintain game data pipelines, aligning them with specific reporting and analytics requirements;
• conduct complex exploratory and statistical analyses in Python and internal tools - including player segmentations and, occasionally, methods like clustering/modeling/ simulating when the problem calls for it;
• build visualizations and develop "numerical intuition" in colleagues who don't work with data daily.
• Set KPIs and implement A/B tests to optimize player income throughout the game lifecycle.
• Organize your own work and support a junior - priorities, requirements, estimates, and leading 1–2 meetings per week;
• Play an active role in shaping the future of the game title by proactively sharing insights with the game team, suggesting process improvements, and shaping analytics practices.
