About the Role:

As a Game Designer focused on Mechanics and Live Balance, you will be responsible for designing and tuning core gameplay systems that drive player flow, engagement, and long-term retention.

You will operate at the intersection of game design, player psychology, and data analytics - continuously optimizing difficulty curves, progression systems, and in-game economy through live data and structured experimentation.

You will have the opportunity to:

  • Design and balance gameplay mechanics and progression systems that reinforce player flow, engagement, and retention
  • Lead continuous post-launch tuning efforts

    └ Analyze player data, win rates, and retention metrics to optimize gameplay curves and in-game economy balance

  • Define and refine difficulty curves, reward structures, and Expected Value models across player segments
  • Collaborate with Live Operations to maintain healthy source/sink systems and ensure sustainable in-game economic flow
  • Work closely with data analysts to evaluate completion rates, retry rates, booster usage, and monetization correlations
  • Build and maintain structured difficulty tiers (e.g., Normal / Hard / Boss / Event)
  • Lead live tuning cycles, including hypothesis design, parameter adjustments, and performance measurement
  • Partner with UX, Art, and Engineering to ensure puzzles clearly communicate goals and deliver strong feedback loops
  • Design and run A/B tests on gameplay parameters, rewards, and difficulty configurations
  • Document tuning frameworks, economic structures, and balancing methodologies to ensure cross-team alignment

Qualifications:

  • Strong interest in game design, level design, player psychology, and data science
  • Clear understanding of how difficulty design, gameplay flow, and economic systems influence retention and monetization
  • Ability to analyze quantitative metrics (e.g., win/loss rates, ARPDAU, Expected Value, retention deltas) and translate insights into actionable design decisions
  • Experience with capacity planning for level production in casual genres, including the use of automation and AI tools
  • Comfortable iterating quickly based on live KPIs and player feedback
  • Ability to thrive in Agile development environments
  • Strong communication skills, with the ability to clearly articulate design intent and logic across disciplines

Nice to Have:

  • Experience designing within hybrid-casual genres
  • Familiarity with A/B testing frameworks and live balancing tools
  • Background in economy simulation, retention modeling, or monetization design
  • Hands-on experience with source/sink modeling and reward pacing systems
  • Experience with expected value modeling, difficulty curve design, and win-rate-based balancing
