• Design and oversee complex A/B testing frameworks to evaluate game features, marketing campaigns, and monetization strategies, monitoring results and delivering actionable recommendations
• Translate complex technical concepts and analytical findings into clear, compelling narratives that drive strategic decisions at the executive level
• Collaborate with engineering teams to implement data solutions in production environments and ensure data infrastructure meets the needs of data science initiatives
• Stay at the forefront of data science advancements, evaluating new methodologies and technologies to maintain competitive advantage
• Serve as the data authority in strategic planning sessions, using your expertise to influence product roadmaps and business strategy
• Build strong relationships with key stakeholders across the organization to understand their needs and ensure data science initiatives deliver measurable business impact

What you bring:

• Genuine passion for video games and a deep understanding of the mobile gaming industry
• 5+ years of experience in analytics, with at least 2 years in a senior role, preferably in gaming or a similar digital product company

• Strong project management skills with ability to prioritize, manage resources, and deliver complex projects on time
• Exceptional communication skills with the ability to present complex findings to both technical and non-technical audiences
• Deep understanding of performance marketing in mobile games, including user acquisition strategies, marketing attribution, ROAS optimization, and LTV modeling
