Senior Linux Graphics Engineer

Responsibilities

• Own the Linux and Vulkan migration of our renderer, from early build to production quality.
• Closely diagnose and fix the differences between our DirectX and Vulkan paths, including memory footprint, shader compilation and pre-caching, driver behavior, synchronization, and rendering artifacts.
• Build the comparison harnesses and regression tests that prove output equivalence across platforms.
• Profile and optimize on Linux, establishing the GPU and CPU profiling workflow and fixing bottlenecks.
• Contribute to the rendering roadmap, taking on broader tasks such as wide-angle and multi-view rendering, reconstruction-based techniques, lighting work, and moving computation onto available GPU capacity.
• Work across the stack, partnering with build, infrastructure, and simulation engineers to ensure the renderer integrates seamlessly with the application, build system, and cloud GPU instances.
• Use AI tooling actively, leveraging LLM-assisted coding and debugging to accelerate the work.

Requirements

• Experience in real-time graphics or engine programming, with at least one product shipped.
• Production experience with Vulkan, including writing and debugging Vulkan render paths, reasoning about memory allocation and descriptor management, and chasing down synchronization and validation-layer issues.
• Linux graphics in production, shipping graphics software on Linux and being comfortable in that environment end to end.
• Highly productive in a large, real C++ codebase with a serious build system and CI.
• Demonstrated ability to profile a frame, identify the real bottleneck, and fix it using tools like RenderDoc, Nsight, or platform equivalents.
• Independence in tackling hard problems without close supervision.
• Strong communication skills, able to explain graphics tradeoffs to non-graphics engineers and give honest schedules.
