You will shape the core progression and monetization systems of our free-to-play titles while owning an events and content roadmap that boosts retention and revenue. You'll blend creative design with data-driven decision-making, transforming KPIs and player insights into clear, high-impact updates.

You'll be a key force in an agile, multidisciplinary and creatively charged development team.

If you want to grow your career in a profitable, internationally recognized company, work closely with world-famous partners and be part of a highly professional international team, Cool Games is the right place for you.

As a Senior Game Designer, you will be responsible for the entire systems and Live Ops lifecycle. This includes designing new casual free-to-play games for desktop, tablets, and mobile, from initial concept through all stages of the product lifecycle. You will design and balance core loops, progression, rewards and game economy, then extend them through Live Ops: in-game events, content drops, experiments and monetization changes that address KPI opportunities, lift retention and grow both IAP and ad revenue.

Armed with analytical tools, you will translate insights into actions, weigh impact versus effort, and continuously iterate to keep our games fresh and competitive. Working side-by-side with developers, artists, QA and marketing in an agile environment, you will articulate strategy and results to stakeholders at every level, ensuring smooth execution. At the same time you will coach and inspire other game designers, fostering a culture of creativity, data-driven decision-making and constant improvement across the team.

• Build and evolve a Live Ops strategy and content roadmap (events, seasonal mechanics, IAP offers and ad-driven promos) that drives engagement and revenue
• Design and implement in-game experiments (A/B tests, event variations) and use the results to inform design decisions; iterate so each update measurably improves retention and monetization
• Specify clear, developer-ready design documents and balancing sheets; be the single source of truth for feature scope, rationale and success metrics
• Stay on top of casual F2P market trends and top-grossing competitors; pitch new content, meta features or mechanics (e.g., collections, passes, streaks, time-limited challenges) that fit our audience
• Collaborate within a multidisciplinary team (design, engineering, art, QA, marketing) to deliver features and Live Ops smoothly; participate in agile rituals to align with development cycles and product goals
• Present product vision, Live Ops plans and post-event analyses; communicate the "why" behind your strategy with data and research to secure buy‑in from internal stakeholders and external partners
• Mentor other game designers and raise team craft through feedback and reviews

• 5+ years of professional experience as a Senior Game Designer within the mobile or web F2P industry, with hands‑on systems/economy and Live Ops experience
