Jobs at Xbox

The Gameplay Engineering Intern will write production C++ code for gameplay systems including physics, weapons, cameras, AI, and hit detection. Responsibilities include debugging crashes, multithreading issues, and memory leaks; profiling and optimizing performance; collaborating with designers and animators; participating in code reviews; and maintaining engine architecture across PC and console platforms.

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.

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.

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.

Drive core runtime engine development for AAA titles: design, implement, optimize, and debug performance, memory, streaming, and multithreading across large C++ codebases and multiple platforms. Profile, investigate complex bugs, collaborate with other engineering teams, participate in design and reviews, and mentor engineers to deliver robust engine technology.

Design, implement, optimize, and debug core runtime engine systems in a large C++ codebase. Improve performance, memory, streaming, multithreading, and platform behavior; profile and resolve low-level bugs; collaborate across engineering teams; participate in design and reviews; mentor engineers and shape long-term engine roadmap.

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. Maintain roadmaps, drive cross-team communication, represent teams in technical discussions, and ensure timely delivery while coaching teams and adapting plans to changing scope.

Design, operate, and automate Demonware's global data-center and cloud network infrastructure. Troubleshoot large-scale, low-latency systems, provision and lifecycle-manage hardware, support virtualized/containerized workloads, participate in on-call rotations, and drive infrastructure-as-code practices.
