As a key player in the AI revolution, NVIDIA is pushing the boundaries of what's possible in accelerated computing. We are seeking an exceptionally dedicated LLM Reinforcement Learning Framework Engineer to join our ambitious team. This role is vital in advancing our large language model (LLM) capabilities, particularly in improving reasoning abilities for math, coding, and agentic AI. Join us and contribute to groundbreaking innovations that will craft the future of computing!

What you’ll be doing:

• Developing and deploying reinforcement learning algorithms for LLM post‑training to improve reasoning and alignment.

• Integrating RL components into NVIDIA’s LLM training and serving stack with a cross‑functional team of engineers and researchers.

• Crafting and running experiments, evaluations, and debugging workflows to ensure robustness, scalability, and reliability in production.

What we need to see:

• Strong Python programming skills with production‑quality PyTorch experience in multi‑GPU and distributed training environments.

• Hands‑on experience with modern LLM frameworks such as NeMo RL, Megatron‑LM, DeepSpeed, vLLM, TensorRT‑LLM, or similar is a big plus.

• Practical experience with reinforcement learning applied to LLMs or large‑scale sequence models.

• Familiarity with async and distributed orchestration (e.g., asyncio, torch.distributed, Ray, or equivalent).

• 3+ years of relevant industry or research experience, and BS/MS (or equivalent) in CS, CE, EE, or a related field.

• Solid foundations in probability, optimization, statistics, and deep learning.

• Understanding of GPU architecture and performance optimization is a strong plus.

• Strong problem‑solving, debugging, and collaboration skills, with a passion for innovation and delivering industry‑leading AI solutions.

Join us at NVIDIA and help build the next generation of reasoning‑capable LLMs that make a lasting impact on the world!
