## About the Role

* MS or Ph.D in Computer Science, AI, Applied Mathematics, or a related field (or equivalent experience).
 * 5+ years of relevant industry experience.
 * Strong foundation in machine learning, deep learning, and optimization.
 * Excellent software engineering skills, including Python and PyTorch.
 * Experience building high-performance software for large-scale AI systems.
 * Strong analytical, debugging, and performance optimization skills.
 * Excellent communication and collaboration skills.

Ways to stand out from the crowd:

Experience in some of the following areas is highly desirable:

 * Distributed training at scale using frameworks like Megatron-LM and Megatron Bridge. It includes FSDP, TP/PP/CP/DP, heterogeneous or per-module parallelism, optimizer research, and efficient sparse or long-context attention.
 * LLM/VLM Post-Training: Supervised fine-tuning (SFT), reinforcement learning for LLMs (e.g., PPO, GRPO, asynchronous RL), and large-scale RL frameworks such as NeMo-RL.
 * Inference Efficiency: Model compression techniques including quantization (FP8, NVFP4, INT4), pruning, knowledge distillation, neural architecture search, and diffusion or non-autoregressive language models.
 * Open-Source AI Infrastructure: Contributing to open-source AI frameworks such as Megatron-LM, Megatron Bridge, NeMo-RL, or Hugging Face Transformers along with experience in GPU performance optimization, distributed systems, latency/throughput analysis, and profiling of large-scale AI workloads.

## Description

NVIDIA is seeking a Senior GenAI Algorithms Engineer to advance the state of the art in foundation model development, training, and deployment. You will work at the intersection of large-scale distributed training, reinforcement learning for LLMs/VLMs, model efficiency, multimodal AI, and open-source AI infrastructure. This role spans the entire GenAI lifecycle from large-scale data preparation to training, post-training, inference optimization, and framework development. You will collaborate with research, product, and infrastructure teams to design new algorithms, optimize existing systems, and contribute to NVIDIA's open-source AI stack, including Megatron-LM, Megatron Bridge, and NeMo-RL.

What You'll Be Doing:

 * Data Curation & Readiness: Design scalable systems for preparing high-quality multimodal datasets for frontier foundation model training.
 * Training Efficiency: Develop algorithms and systems that improve the scalability, efficiency, and cost of large-scale pre-training and post-training.
 * Inference Efficiency: Advance techniques that improve inference performance, reduce deployment cost, and enable efficient serving across cloud and edge platforms.
 * Open-Source AI Infrastructure: Develop reusable infrastructure and contribute brand new model support to NVIDIA's open-source GenAI training platform.
