Join us as we continue to shape the Diablo universe! Diablo games are action RPG experiences with endless evil to slaughter, countless abilities to master, nightmarish Dungeons, and legendary loot. Come work with us, and together we'll create something amazing. Our team of passionate developers is growing.
We are seeking an Engine Systems Engineer to assist in the creation of new ARPG experiences within one of Blizzard's most iconic worlds, Diablo. In this role, you will help advance the core technology that powers our game by improving foundational engine infrastructure (streaming, asset loading, performance systems, and platform support) as well as core runtime systems such as animation, VFX, physics, and audio. You'll also ensure smooth, stable gameplay experiences through thoughtful performance optimization, efficient content delivery, and robust multi-platform integration. This is a unique opportunity to work closely with cross-disciplinary partners to support both creative and technical goals, leverage platform SDKs, and solve complex challenges that bring immersive, high-fidelity gameplay to life across a wide range of hardware.
This role offers a flexible hybrid work week, with a mix of remote and on-site days. While hybrid is the standard arrangement, you're also welcome to work on-site full-time if you prefer. Our primary studio locations are in Albany, NY, and Irvine, CA.
Responsibilities:

• Design, implement, and maintain core engine features by collaborating closely with designers, artists, and fellow engineers to support both creative and technical goals.

• Improve engine workflows and pipelines by identifying bottlenecks, simplifying processes, and enabling teams to build content more efficiently.

• Ensure client and runtime stability across multiple platforms by diagnosing complex issues, fixing bugs, and strengthening system reliability.

• Advance the game engine through performance tuning, scalability work, and platform-specific optimization to support long-term growth of the project.

Minimum Requirements:

• 5+ years of professional software engineering experience, with a strong focus on modern C++ in real-time or game development environments.

• Deep understanding of memory management, performance considerations, and software architecture.

• Strong grasp of core data structures and practical insight into when and how to use them effectively.

• Demonstrated experience optimizing both code and data layouts for performance and memory efficiency.

• Excellent communication skills and comfort working closely with designers, artists, producers, and other engineers.

• Hands-on experience with multithreaded programming and a solid understanding of concurrency challenges.

Bonus Points:

• Background in developing or optimizing games for console platforms (PlayStation, Xbox, or Nintendo Switch).

• Experience with C# or experience working with C#-based tools or systems.

• Familiarity with Python, Lua, or similar scripting languages.

• Ability to discuss or share examples of C++ work, such as custom engines, renderers, compilers, embedded systems, or similar projects (professional, academic, or personal).
