Senior Software Engineer - Planner GPU Compute: our view in 3 lines...
- The Role:This role is for a senior software engineer focused on GPU compute for the motion planner in Zoox’s autonomous robotaxi system.
- The Person:The person will analyze performance metrics, identify GPU hotspots, adapt the planner to multiple GPU architectures, optimize ML models for latency and memory use, and support engineers on CUDA and GPU performance.
- Requirements:The ideal candidate has strong knowledge of CUDA, C++, and Linux development environments, plus experience with GPU performance, Nsight, and large code bases.
About the role
Zoox made the world’s first purpose-built commercial robotaxi, combining advanced self-driving hardware and software. In order to ensure safe operation, low latency and consistent resource utilization are critical. The Planner Compute team is responsible for the performance of the largest single software component within the autonomy stack, the motion planner.
The Planner Compute team is looking for an expert in GPU performance. You will instrument, monitor, analyze and optimize GPU-based algorithms that are performance-critical for our solution. The scope for GPU usage ranges from machine learning inference to custom CUDA kernels written specifically for the motion planner.
