Our team works on cutting-edge rendering technologies, ensuring optimal performance across various platforms. As we continue to grow, we are looking for an experienced DX12 Optimisation Expert to enhance graphics performance and efficiency.

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

Skills

Must have

• 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

• Experience with Unreal Engine 4/5, Unity, or proprietary engines
