What you'd actually do

You will be engaged as core contributors to Nemotron models post-training, working at the intersection of the areas: 1) Synthetic data and algorithmic research for agentic RL 2) Data and training Infrastructure implementation 3) Collaborating in vendor data acquisition and experimentation 4) Large-scale research & production model post-training

Advance open-source foundation models by developing training data, benchmarks, LLMs and software (including [NeMo-RL](https://github.com/NVIDIA-NeMo/RL), Nemo-Gym and yet to be announced software)

Solve large-scale, end-to-end foundation model post-training challenges, spanning the full model lifecycle from initial orchestration, data pre-processing, running of model training and tuning, to model deployment.

Publish and present your results at academic and industry conferences
