Description

You will own the performance debugging and optimization of DirectX 12 graphics systems.

This role is remote.

Responsibilities

• Reproduce reported DirectX 12 performance issues using testing lab data.
• Capture and analyze GPU/CPU profiles and traces using PIX, GPUView/ETW, and vendor profilers to identify bottlenecks.
• Isolate root causes from performance counters and propose actionable solutions.
• Create detailed performance reports with reproduction steps, metrics, and hotspot summaries.
• Collaborate with graphics driver and runtime engineers to validate fixes and confirm improvements.

Required Skills

• 5+ years of experience in graphics drivers and GPU architecture.
• Proficiency in C/C++ with the ability to interpret performance-sensitive code.
• Deep understanding of DirectX 12 core concepts, shaders (HLSL, SPIRV), and the GPU graphics pipeline.
• Experience with graphics profiling tools such as PIX, GPUView, and Radeon GPU Profiler.
• Scripting and automation skills in Python, PowerShell, and Bash.
• Proficiency working in both Windows and Linux environments.
• Strong grasp of real-time rendering fundamentals and GPU concepts.

Preferred Skills

• Experience with ETW (Event Tracing for Windows) analysis.
