Senior Systems Engineer

That’s No Moon is an independent studio of storytellers and game-makers who believe in the power of narrative-driven experiences. With a diverse team of talented developers, their shared vision is to create the future of AAA experiences with a culture of creativity, collaboration, and responsible production practices.

Responsibilities:

• Profile and optimize CPU, memory, and I/O performance on console platforms, driving the game to its frame-time, memory, and load-time targets ahead of certification and launch.
• Diagnose hitches, streaming stalls, and memory pressure using platform and engine profiling tools, and fix root causes rather than symptoms.
• Help maintain core systems such as level loading and streaming, ensuring they perform within console hardware constraints.
• Break down optimization and stabilization work, assess dependencies and risk, and prioritize by impact with production and engineering leadership.
• Collaborate with engineers and other disciplines to find solutions that protect both quality and performance.
• Architect, implement, and maintain production-quality C/C++ for systems, features, tools, and workflows.
• Support console certification and platform requirements related to performance, memory, and stability.
• Analyze different approaches to solve problems and discuss the tradeoffs between performance, quality, and risk late in production.
• Write and maintain documentation on profiling workflows, performance budgets, and optimization findings.

Requirements & Skills:

• Shipped at least one AAA game, with hands-on experience on current-generation consoles (PS5, Xbox Series X|S).
• Strong knowledge of C++, including performance-oriented programming (memory layout, cache behavior, multithreading).
• Proven CPU, GPU, and memory profiling and optimization experience, using tools such as Unreal Insights, PIX, Razor, or equivalent platform tools.
• Experience with console memory management, asset streaming, and load-time optimization.
• Strong math skills.
• (Strongly preferred) Unreal Engine experience, ideally UE5.
• (Bonus) Experience with console certification and submission processes.

Qualities:

• Good communication skills visually, verbally, and written.
• Ability to work independently with minimal supervision.
• Calm, pragmatic decision-making under deadline pressure.
• Ability to resolve conflicts.
