About The Position

That's No Moon is seeking a Senior Systems Engineer to help bring a AAA title across the finish line. The role focuses on profiling, diagnosing, and optimizing performance and memory on current-generation console platforms while maintaining foundational systems such as level loading and streaming. The engineer will help meet frame-time, memory, and load-time targets ahead of certification and launch, and support console performance, memory, and stability requirements. The position works closely with engineering leadership and other disciplines to prioritize stabilization and optimization work, assess dependencies and risks, and balance performance, quality, and production constraints. It also involves developing and maintaining production-quality C/C++ systems, features, tools, and workflows, and documenting profiling workflows, performance budgets, and optimization findings. The role may be eligible for incentive compensation, including equity and profit share, in addition to base pay. The estimated U.S. base pay range is $160,900–$186,744.
