DirectX12 Optimisation Expert

Full-time

Company that creates foundation for next-generation computing seek a DX12 Optimisation Expert to advance the cutting-edge rendering technologies.

Responsibilities:

Optimize rendering pipelines for DirectX 12, ensuring top-tier performance on PC and gaming consoles;
Identify and eliminate bottlenecks in the graphics pipeline, improving GPU/CPU efficiency and reducing frame times;
Develop and implement advanced optimization techniques, including GPU culling, Async Compute, and memory management improvements;
Perform in-depth performance profiling and diagnostics using tools like PIX, NSight, RenderDoc;
Work closely with driver engineers, rendering engineers, and game developers to integrate performance enhancements;
Adapt and optimize existing rendering techniques for DX12.

Must have skills:

Strong C++ programming skills and experience with GPU APIs: DirectX 12 (mandatory), Vulkan or Metal (nice to have);
Implemented or contributed to path tracing or physically based rendering (PBR) pipelines;
Deep understanding of GPU architecture, pipelines, memory systems, and parallel execution models;
Experience with low-level graphics programming and optimizing performance for modern GPUs (AMD, NVIDIA);
Familiarity with GPU driver architecture and its impact on rendering performance;
Proficiency in HLSL, including shader optimization techniques for performance and quality;
Experience in multi-threaded rendering systems and asynchronous compute;
Solid experience with performance profiling tools (e.g., PIX, RenderDoc, NSight Graphics);
Experience with DirectX Raytracing (DXR) and ray tracing pipeline shaders (RayGen, ClosestHit, AnyHit, Miss, Callable);
Familiarity with GPU Compute Shaders and ML techniques like inference.

Nice to have
