About the role

About the Role We are building a next-generation AI-driven anti-cheating system for competitive strategy games.
Unlike traditional fraud detection, our challenge sits at the intersection of:

  • 🎮 Game AI & player behavior modeling
  • 🧠 Reinforcement learning & decision systems
  • 🔍 Anomaly detection under adversarial conditions

You will work on identifying non-obvious, strategic cheating behaviors in complex environments where players actively adapt to detection systems. This is not rule-based detection — this is behavioral intelligence at scale.


What You’ll Do 1️⃣ Behavioral Modeling & Detection

  • Design machine learning / deep learning models to detect cheating patterns
  • Model player behavior sequences, strategies, and anomalies
  • Build systems that distinguish:
  • high-skill play vs. AI-assisted play
  • natural variance vs. exploitation

2️⃣ Anti-Cheating System Design

  • Develop scalable detection pipelines (offline + real-time)
  • Build feature systems from gameplay logs / event streams
  • Design evaluation frameworks for detection accuracy & robustness

3️⃣ ML / DL / Advanced Techniques

  • Apply and experiment with:
  • sequence modeling (RNN / Transformer-based)
  • anomaly detection
  • graph-based or behavioral embeddings
  • Explore intersections with:
  • reinforcement learning
  • game-theoretic modeling
  • adversarial ML

4️⃣ Collaboration with AI & Engineering Teams

  • Work closely with:
  • Gameplay AI / RL researchers
  • Backend / data engineering teams
  • Translate models into production systems

What We’re Looking For

✅ Core Requirements

  • 4+ years in Data Science / Machine Learning roles
  • Strong foundation in:
  • deep learning
  • statistical modeling
  • Experience in one or more of:
  • fraud detection / AML
  • risk modeling
  • anomaly detection
  • behavioral analytics

✅ Strong Signals (Big Plus)

  • Experience with:
  • sequence models (LSTM / Transformer)
  • large-scale behavioral data
  • real-time detection systems
  • Exposure to:
  • reinforcement learning
  • game AI
  • adversarial systems

✅ Technical Stack

  • Python (must)
  • PyTorch / TensorFlow
  • SQL / data pipelines
  • Experience working with large-scale datasets

Why This Role is Interesting

  • 🚀 Work on problems similar to fraud detection at scale — but harder
  • 🎯 Direct impact on real-money / competitive environments
  • 🧠 Blend of:
  • ML research
  • production systems
  • game AI
  • 🌍 Fully remote, globally distributed team

Location & Visa

  • 🌏 Remote-first (global team)
  • 🇯🇵 Japan relocation supported (visa sponsorship available for qualified candidates)

Who This Role is Perfect For

  • Data scientists bored with “dashboard ML”
  • Fraud / AML experts who want more complex, adversarial systems
  • ML engineers who want to work closer to decision intelligence & behavior modeling
