Designs and develops advanced anti-cheat and game security systems for Call of Duty. Responsibilities include strengthening protection frameworks, creating cheat detection mechanisms, optimizing and debugging complex C++ systems, analyzing compiled code, and collaborating across studios. The role requires expertise in large-scale software development, algorithms, data structures, CI/CD, automation, performance tuning, and low-level systems, with preferred experience in game engines, reverse engineering, DevOps, cryptography, and anti-cheat technology.

Supports Treyarch’s gameplay engineering team by prototyping, implementing, and refining gameplay systems, features, and mechanics. Troubleshoots game code, collaborates with designers and artists, contributes to gameplay balancing based on playtest feedback, and documents technical processes. Interns receive mentorship while developing functional gameplay prototypes and contributing to game development projects.

Lead product strategy and roadmap for anti-cheat and game security across Call of Duty titles. Define detection, prevention, and enforcement capabilities, partner with engineering, data science, threat intel, and ops, use telemetry and experimentation to improve systems, and drive incident response and cross-functional alignment.

Design, implement, and maintain C++ client SDK libraries, build pipelines, and internal tooling. Debug client-network-backend issues, improve CI/build reliability, collaborate with game teams, write technical designs, and mentor engineers.

Lead and manage multiple technical projects for Demonware’s Game Services, coordinating stakeholders, schedules, budgets, risks, and deliverables.
