At NVIDIA, we’re building the foundation for the next generation of Physical AI. Our Cosmos team is passionate about developing robust, production-grade open-source Machine Learning software to support machine learning and generative-AI research at scale. We’re looking for expert-level
Python engineers who are passionate about building production-ready systems and want to make a lasting impact through open-source contributions.
If you care deeply about software craftsmanship, maintainability, and performance—and have hands-on experience building ML systems—this role is for you.
What You’ll Be Doing
- Develop and maintain high-quality, modular, and well-tested Python code for large-scale ML infrastructure. See https://github.com/nvidia-cosmos
- Design and optimize post-training, inference, and data processing pipelines used by ground breaking ML models.
- Collaborate with research and product teams to bring ML systems from prototype to production.
- Contribute to open-source projects and build internal tools that enable scalable AI experimentation.
- Improve performance, reliability, and observability of large distributed systems.
- Support teammates through design reviews, code reviews, and collaborative development.
What We Need To See
- Pursuing BS, MS or PhD degree in Computer Science, Engineering, or a related field, or equivalent experience
- Strong proficiency in Python and a track record of delivering production-quality software.
- Experience with PyTorch (or similar frameworks such as JAX or TensorFlow), especially in real-world applications.
- Deep understanding of ML system design, training loops, data loaders, evaluation, and model serving.
- Familiarity with containerization, CI/CD, and maintaining in production environments
- Comfortable working with large codebases, building reusable libraries, and writing documentation and tests.
Ways To Stand Out In The Crowd
- Contributions to open-source ML or Python infrastructure projects.
- Background in scaling ML training and inference systems across GPUs as well as experience building libraries that wrap or extend PyTorch functionality.
- Prior exposure to multimodal models or simulation environments (vision, language, audio).
- Familiarity with NVIDIA’s GPU compute stack or high-performance computing clusters.
- Experience with distributed computing tools like DDP, FSDP, ZeRO, or Ray.
