• 7+ years of professional software engineering experience, including technical lead experience.
• Expert-level CUDA and modern C++ development, plus strong Python.
• Experience with NVIDIA Nsight tools to diagnose bottlenecks across CPU, GPU, memory, I/O and networking.
• Hands-on experience accelerating and scaling simulation workloads on Omniverse and Isaac Sim across multi-GPU and distributed systems.
• Deep knowledge of NVIDIA GPU architecture and memory hierarchy.
• Experience building agentic AI systems or LLM-driven developer tooling.
• Proven Linux experience and containerized GPU workloads with Docker, Kubernetes and Slurm on CoreWeave, AWS or Azure.
• Strong understanding of parallel computing, memory hierarchies and multi-GPU/distributed scaling (NCCL, MPI).
• Experience with CI/CD, automated regression testing and performance benchmarking.
• On-site work in Irving, TX.

Responsibilities

• Profile and optimize workloads, diagnosing bottlenecks across CPU, GPU, memory, I/O, storage and networking using NVIDIA Nsight tools.
• Refactor and tune core simulation code in CUDA, C++ and Python to maximize hardware utilization, throughput and execution speed.
• Design and deploy agentic AI systems that automatically analyze and optimize runtime code performance.
• Accelerate and scale simulation workloads on NVIDIA Omniverse and Isaac Sim across multi-GPU and distributed systems.
• Manage and optimize containerized GPU jobs using Docker, Kubernetes and Slurm across cloud environments.
• Implement automated regression testing, observability and performance benchmarking for continuous performance tracking.
• Partner with robotics, perception and AI teams to drive GPU performance best practices and evaluate future hardware and software infrastructure.
