Senior RL Post-Training Frameworks Architect

NVIDIA is building an RL Frameworks engineering team to develop the open-source tools and infrastructure that AI researchers and post-training teams depend on. You will architect and build RL post-training infrastructure that scales from single-GPU experiments to production across thousands of nodes, tuning training-inference-rollout loops for performance on GPUs, CPUs, and LPUs.

The role spans fault tolerance, elastic scaling, and fast restarts, and you will partner with teams building
