## About the Role

* BS in computer science or related field and 3+ years of experience.
 * Strong knowledge of CUDA as applied to recent GPU microarchitectures (e.g., Ampere, Blackwell) and experience debugging/optimizing GPU kernels using tools like Nsight.
 * Strong knowledge of C++ and experience in large code bases, comfortable in Linux development environments.
 * Experience in development, debugging, and profiling of complex multiprocess systems (e.g., robotic systems, game engines).

## Description

* Build real-time instrumentation for performance monitoring (CPU, GPU, latency, memory) and develop offline benchmarking frameworks, tools, and scripts to evaluate & analyze performance at scale in CI/vehicle, and establish budgets for next-gen architectures.
 * Analyze performance metrics to identify GPU hotspots and root causes, and propose and co-implement actionable solutions with component teams.
 * Support teams on bringing serial algorithms to the GPU to maximize compute utilization and improve overall latency.
 * Work as part of the Core team to design a middleware framework that promotes by default efficient and performant code development by maximizing CPU and GPU., * Experience with GPU kernel development in a real-time environment, including PTX-level programming, CPU SIMD instructions (e.g., AVX intrinsics), and custom CUDA layers with frameworks like TensorRT & XLA.
 * Hands-on work with ML model optimization (post-training quantization, layer pruning, etc) or hand-tuning GPU kernels (in OpenGL, CUDA, RocM or similar).
 * Proficiency with SQL, DataBricks, Looker, or other business intelligence tools.
