Responsibilities
Performance Benchmarking: Run and automate standard LLM quality benchmarks (GSM8K, MMLU) alongside custom performance suites for specific workloads (e.g., long-context window, KV cache reuse)
Infrastructure Validation: Create automated acceptance tests for new GPU clusters across x86 and ARM systems, measuring GPU memory bandwidth, networking throughput, and multi-node networking performance
Model Dev Experience: Develop and maintain internal GPU-enabled development environments (similar to GitHub Codespaces). You will ensure the team has seamless, high-performance "dev machines" optimized for model experimentation
Tool Development: Build and contribute to tools such as InferenceMAX and genai-bench to automate model evaluation and optimization
Deep Hardware Profiling: Use PyTorch Profiler and NVIDIA Nsight Systems to collect performance profiles, identify bottlenecks, and debug the NVIDIA compute/networking stack
Monitoring & Observability: Develop real-time dashboards and alerts to monitor system health, model startup times, and runtime performance
Continuous Integration: Automate performance testing via CI/CD pipelines to catch regressions in model setups before they hit production
Optimization Automation: Build tools to find the "Pareto frontier"—identifying the absolute best configuration (latency vs. cost vs. quality) for a given model and workload
Qualification
Required
A Love for Systems & Hardware: You aren't just interested in the AI; you want to understand GPU memory subsystems, InfiniBand, and how data moves across a cluster
An Automation Mindset: You believe that if a task has to be done twice, it should be scripted. You have a passion for stress-testing and fuzzy testing to find the 'breaking point' of a system
Mathematical Curiosity: A desire to understand the underlying math of Transformers and how it translates into FLOPs and memory requirements
Interest in Optimization: You are excited to learn about (or already play with) quantization, speculative decoding, disaggregated serving, and kernel-level optimizations
Preferred
Familiarity with Python
Eagerness to master the NVIDIA software stack
C++ familiarity is good to have
