Senior Software Engineer - GPU Local AI Platforms (Westford)

NVIDIA has been transforming computer graphics, PC gaming, and accelerated computing for more than 25 years. It’s a unique legacy of innovation that’s fueled by great technology—and amazing people. Today, we’re tapping into the unlimited potential of AI to define the next era of computing. An era in which our GPU acts as the brains of computers, robots, and self-driving cars that can understand the world. Doing what’s never been done before takes vision, innovation, and the world’s best talent. As an NVIDIAN, you’ll be immersed in a diverse, supportive environment where everyone is inspired to do their best work. Come join the team and see how you can make a lasting impact on the world.NVIDIA's Local AI team is building the software stack that makes large language models and generative AI applications run at maximum efficiency on NVIDIA edge AI hardware. The AI ecosystem moves fast; our job is to make sure end users get the best experience. We own the platform — performance, CI/CD pipelines, validated recipes, and model bring-up infrastructure — that lets developers run groundbreaking LLMs out of the box. The open-source community builds fast; our platform is what turns community innovation into something developers and partners can rely on at scale.What you'll be doing:Track and evaluate innovations in leading open-source LLM inference frameworks — identify performance-critical features and algorithmic improvements relevant to NVIDIA edge AI hardwareAnalyze how new model architectures and inference algorithms (attention variants, MoE routing, speculative decoding, multi-token prediction, quantized inference) map onto NVIDIA GPU architecture — identify mismatch, fallback paths, and optimization opportunitiesCharacterize multi-node inference behavior: collective communication primitives (NCCL/RCCL), topology-aware all-reduce strategies, and parallelism efficiency on edge cluster configurationsProduce performance analysis reports mapping theoretical hardware limits (memory bandwidth, FLOP/s, interconnect throughput) to observed inference throughput, latency, and utilizationOwn the model validation workflow for new model releases: architecture compatibility assessment, inference recipe development, performance characterization, and publication to developer recipe sitesDevelop and maintain developer-facing inference recipes: keep them accurate as frameworks evolve, automate staleness detection, and build feedback loops from CI results to recipe updatesEngage with community and partners on model bring-up questions; serve as the technical point of contact for hardware-specific inference issues related to partner concernsWhat we need to see:BS, MS, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or equivalent experience.12+ years of software engineering with depth in GPU computing, ML systems, or high-performance inferenceStrong Python or C++ programming, software design, and software engineering skills.Hands-on experience with GPU kernel development or optimization (CUDA/C++, Triton, or equivalent) — you understand how thread blocks, memory hierarchy, and warp execution affect real-world performanceWorking knowledge of LLM inference internals: attention mechanisms, KV-cache management, continuous batching, quantization formats, and tensor parallelismContainer engineering expertise: multi-architecture Docker or OCI builds, layer optimization, runtime configuration, NVIDIA Container ToolkitStrong analytical skills: ability to form a performance hypothesis, design an experiment, interpret results, and communicate findings clearlyWidely considered to be one of the technology world’s most desirable employers, NVIDIA offers highly competitive salaries and a comprehensive benefits package.
