Senior Software Engineer C++ GPU Performance at Zoox

Zoox is building the worlds most advanced self-driving hardware and software solution. The efficiency demands of such a system require an expert fine tuning of both the compute hardware architecture as well as the algorithms and middleware that runs on it to achieve maximum throughput at the most optimal power levels.The Software Performance teams mission is to analyze optimize and provide guidance to the software and hardware teams in order to meet the required specifications. As a GPU performance software engineer within the Software Performance team you will instrument monitor analyze and optimize GPU-based algorithms that are performance-critical for our solution. The scope for GPU usage ranges from traditional computer vision and deep learning architectures to complex geometric reasoning and multi-agent decision making. Your work will strongly influence design decisions of future compute platforms & resource allocation.In this role you will: 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.QualificationsBS in computer science or related field and 7 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).Bonus QualificationsExperience 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.$217000 - $307000 a yearBase Salary RangeThere are three major components to compensation for this position: salary Amazon Restricted Stock Units (RSUs) and Zoox Stock Appreciation Rights. A sign-on bonus may be offered as part of the compensation package. The listed range applies only to the base salary. Compensation will vary based on geographic location and level. Leveling as well as positioning within a level is determined by a range of factors including but not limited to a candidates relevant years of experience domain knowledge and interview performance.
