Position: Software Developer 2
Location: 100% Remote
Duration: 6 months Contract
Pay rate- $45-49/hr on W2
Job Description:
This role’s main responsibility is to triage and diagnose DirectX 12 game performance issues by collecting GPU/CPU traces and comparing performance differences between Windows and Linux graphics stacks (runtime, drivers, and compilers), then communicating clear findings and recommended next steps to graphics driver and runtime engineers.
Responsibilities:
• Reproduce reported DirectX 12 performance issues from data produced by our testing lab.
• Capture GPU/CPU profiles and traces using tools such as PIX (timing captures), GPUView/ETW, and vendor profilers (e.g., Radeon GPU Profiler) to identify bottlenecks (GPU-bound vs. CPU-bound, synchronization, shader occupancy, pipelining, etc.).
• Analyze traces and performance counters to isolate the likely root cause and propose actionable next steps.
• Create clear performance write-ups with reproduction steps, captures, metrics, and a concise summary of suspected hotspots.
• Partner with graphics driver and runtime engineers to validate hypotheses, test fixes, and confirm performance improvements and regressions.
Skills:
• Understanding of real-time rendering fundamentals and the GPU graphics pipeline (draw calls, state changes, shaders, textures, buffers).
• Understanding of GPU architecture basics (waves/warps, occupancy, caches, memory bandwidth) and shader ISA at a high level.
• DirectX 12 familiarity (core concepts such as command queues/lists, descriptor heaps, resource states/barriers) and basic shader concepts in HLSL & SPIRV.
• Hands-on experience with profiling tools (PIX, RGP, GPUView, WPA/WPR) and interpreting timing/counter data.
• Programming skills in C/C++ with ability to read and reason about performance-sensitive code.
• Comfortable working in Windows environments (command line basics, driver/runtime builds) and strong written communication for bug reports and triage summaries.
• Comfortable working in Linux (shell, services, and basic scripting).
• Scripting for automation (Python, PowerShell, or Bash) and basic data analysis (CSV, spreadsheets, simple plots).
• Exposure to Windows graphics stack and debugging concepts (WDDM, DXGI, ETW providers, driver symbol debugging)
Education/Experience:
• Bachelor''s degree in computer science, software engineering or relevant field required.
• 2-4 years’ experience required.
