About the role

The role is remote and suits someone who wants to work from home or join the Amsterdam studio.

Key responsibilities

• Design and balance core loops, progression, rewards and game economy, then extend them through LiveOps: events, content drops, experiments and monetization changes that improve retention and IAP and ad revenue.
• Define and maintain systems design for core loops, progression, rewards and economy, aligned with player needs and business goals.
• Build and evolve a LiveOps strategy and content roadmap (events, seasonal mechanics, IAP offers and ad-driven promos).
• Design and run in-game experiments (A/B tests, event variations) and use the results to inform design decisions.
• Write clear, developer-ready design documents and balancing sheets, and act as the single source of truth for feature scope, rationale and success metrics.
• Stay up to date on casual F2P trends and top-grossing competitors, and pitch new content, meta features or mechanics such as collections, passes, streaks and time-limited challenges.
• Work in an agile, multidisciplinary team with developers, artists, QA and marketing, and present product vision, LiveOps plans and post-event analyses to stakeholders.
• Mentor other game designers and foster a culture of data-driven decision-making.

Required profile

• 5+ years of professional experience as a Senior Game Designer in the mobile or web F2P industry, with hands-on systems/economy and LiveOps experience.
• Deep familiarity with top-grossing casual games and F2P mechanics, and ability to anticipate shifts in player behavior or monetization patterns.
• Ability to turn complex data and KPIs into actionable design changes and roadmaps.
• Strong written and verbal English, with concise specs and clear presentation skills.
• Proven experience in cross-functional teams and in mentorship or leadership.

Required skills

• Bonus: game economy design specialization, puzzle/casual background, HTML5/web distribution experience.
