Qualifications

• 6+ years of experience in mobile games, ideally across casual or hybrid-casual products.
• Strong game design experience combined with product management or meaningful product ownership.
• Experience taking games or significant products from concept through launch and post-launch iteration.
• A track record of owning product outcomes and KPIs, not just individual features.
• Strong understanding of gameplay systems, progression, economy, UX, retention, monetization, and LiveOps.
• Strong understanding of F2P game economics and metrics, including retention, engagement, monetization, LTV, CPI, and related product performance indicators.
• Comfort working with analytics and experimentation, including interpreting data, forming hypotheses, designing tests, and acting on results.
• Ability to turn ambiguous opportunities into clear product direction and executable priorities.
• High ownership and independent decision-making. You move quickly and don't wait for perfect information.
• Strong execution mindset. You build, ship, learn, and improve rather than getting stuck in process.

Responsibilities

• Identify and evaluate new game opportunities through market analysis, competitor deconstruction, player insights, and product data.
• Turn opportunities into clear product bets, defining the concept, target audience, core loop, product hypothesis, success metrics, and commercial opportunity.
• Own AI-assisted game design across core loops, systems, progression, economy, UX, retention, and monetization.
• Rapidly prototype and validate game concepts using AI-assisted tools and lightweight development workflows.
• Define success metrics, analyze player behavior and test results, and make clear recommendations on whether to scale, iterate, or kill.
• Own product priorities and make trade-offs based on player impact, data, development effort, and business potential.
• Continuously improve games based on retention, engagement, monetization, experimentation, and player behavior.
• Partner closely with leadership to evolve how AI is used to design, prototype, build, and scale games faster.
