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
