About this role
Aditi Consulting is seeking a Software Development Engineer to diagnose DirectX 12 game performance issues. The role involves analyzing GPU/CPU performance data and collaborating with engineers to improve graphics performance across platforms.
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
Requirements:
- 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 the 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)
- Bachelor's degree in computer science, software engineering, or a relevant field required
- 2-4 years experience required
