SoftwareEngineer,DGXCloudAIInfrastructure

NVIDIA is at the forefront of the generative AI revolution, building the software and systems that power the world’s most advanced large language model workloads. We are looking for a Software Engineer focused on bring-up, triage, benchmarking, analysis, and optimization of distributed training and inference workloads across NVIDIA GPU platforms at the largest scales we run. In this role you will help bring up, benchmark, and debug distributed LLM workloads on multi-GPU and multi-node deployments, and own the design and implementation of the benchmarking tooling, automation, and debugging workflows that support them. This is a hands-on role for an engineer who enjoys deep technical problems across deep learning systems, GPU performance, distributed computing, and large-scale operations. **What you’ll be doing:** * Bring up, validate, and debug large-scale AI clusters, infrastructure, and end-to-end workloads. * Bring up, tune, and benchmark AI pre-training, post-training, and inference workloads using PyTorch, NeMo / Megatron, TensorRT-LLM, and adjacent NVIDIA AI software stacks. * Perform root-cause analysis of failures in large distributed environments * Contribute to the resilience and failure-attribution tooling that detects, triages, and attributes node, fabric, and workload failures across the cluster. * Build and maintain repeatable benchmark suites, automation, acceptance criteria, and qualification workflows on new platforms. * Tune runtime settings, communication parameters, and deployment configurations in close partnership with framework, systems, and platform teams. * Deliver actionable, data-driven recommendations based on profiling, benchmark results, and cluster characterization. **What we need to see:** * Bachelor’s or Master’s in Computer Science or a related technical field (or equivalent experience). * 3+ years of experience developing software for AI, HPC, or systems-level applications. * Hands-on experience with multi-GPU or multi-node workload
