●      Candidates who can communicate with the CEO with a sense of ownership.

●      Candidates who can independently develop mockups using Unity and communicate based on highly feasible ideas.

●      Candidates with a strong interest in game design, level design, player psychology, and data science

are required skills.

●      F2P system design skills: Ability to integrate difficulty, progress flow, and economics (rewards/charges) based on the Puzzle/Merge genre, and explain the impact on Retention/Monetization (LTV, etc.)

●      Data-driven improvement cycle operation skills: Ability to create actions from win/loss rates, EV, retention differences, live KPIs, etc., and rapidly cycle through hypothesis → implementation → measurement → learning

●      Specification and consensus-building communication skills: Ability to clearly share design intent, expected effects, and risks with Engineering/Art/QA/analysis/operation based on PRD/Mock/data specifications and gain agreement

●      Production planning and efficiency skills: Ability to estimate the production volume/man-hours for level production and develop productivity improvement plans including AI/automation

●      Understanding the impact of difficulty design, flow design, and economic systems on retention rate and monetization

●      Ability to analyze quantitative data (win/loss rates, ARPDAU, Expected Value, Retention Difference, etc.) and translate it into design actions

●      Experience in capacity planning for level production in casual genres (including automation and AI tool utilization)

●      Ability to quickly implement improvements based on live KPIs and user feedback

●      Ability to deliver results in an agile environment

●      Strong communication skills to clearly convey design intent and logic to other departments

●      Experience designing in the hybrid casual genre

Welcome skills

●       Experiment and operational infrastructure utilization skills: Ability to understand A/B testing infrastructure and Remote Config, etc., and to safely perform balancing and verification even after release.

●       Modeling/simulation design skills: Ability to model (predict) the economy, continuity, and revenue, and use this for design decision-making.

●       Economic cycle (Source/Sink, reward pace) design skills: Ability to design the supply and consumption of currency/rewards to suppress inflation/depletion.

●       Quantitative balancing skills: Ability to perform adjustments with high reproducibility using expected value, difficulty curve, and win rate data.

●       Understanding of A/B testing frameworks and live balancing tools.

●       Background in economic simulation, retention modeling, and monetization design.

●       Practical experience in source/sink design and reward pacing design.

●       Experience in expected value modeling, difficulty curve design, and win rate-based balancing.

Desired candidate profile

●       Someone who can discuss the common communication foundations of a game designer (UA / Retention / Engagement / Monetization / LiveOps) with evidence and examples, centered on the player experience.

●       Someone who can rapidly cycle through hypothesis → implementation (specification) → measurement → learning, and continuously update the optimal solution.

●       Someone who can consistently present "new perspectives" as options during the consensus-building stage with stakeholders.

●       Someone who is data-driven but doesn't lose sight of the essence of the player experience.

●       A designer who can rapidly iterate through hypotheses and communicate with numbers.

●       Possesses a systems thinking ability that allows for a comprehensive view of the balance between economic design and game experience.

●       Someone with the logical thinking skills to engage in discussions on an equal footing with those in Data Science, Product, and LiveOps.

●       Someone who enjoys change and continues to search for new optimal solutions.
