NVIDIA is seeking a Principal Scientist to lead the technical direction for synthetic data generation within its frontier model efforts. This role involves defining and building open-source libraries in the NVIDIA NeMo ecosystem to generate synthetic datasets for various data types, including text and multimodal data. The position combines software engineering with applied research in generative methods and requires collaboration with multiple teams. The ideal candidate will have a strong background in synthetic data generation and a passion for advancing AI technologies.

• PhD in Computer Science, Machine Learning, Statistics, or a related field, or equivalent experience.
• 15+ years of engineering and research experience in synthetic data generation, generative modeling, multimodal machine learning, or related areas.
• Deep technical understanding of LLMs and their training stages.
• Proven track record of developing or maintaining software libraries used by a broad developer community.
• Experience building and optimizing scalable data pipelines for large-scale model training.
• Strong publication record at premier venues such as NeurIPS, ICML, ICLR, ACL or similar.

• Build and scale data generation pipelines using LLM-based methods combined with automated quality evaluation.
• Pioneer data generation for agentic and tool-use training, including synthetic trajectories and multi-turn interactions.
• Advance multimodal synthetic data generation in partnership with NVIDIA's model teams.
• Develop and maintain open-source libraries and SDKs with clean APIs and strong documentation.
• Drive software excellence with modern tooling and architecture.
• Publish original research at top machine learning and AI conferences.
• Mentor scientists and engineers across the team to raise the technical bar.

• Employees at NVIDIA are often offered comprehensive, day-one benefits—including medical, dental, and vision coverage with HSA support, life and disability insurance, an Employee Assistance Program, and a 401(k) with auto-enrollment. Many roles also have generous time off and holidays, donation matching (up to $10,000), and a wide menu of extras like FSAs, commuter benefits, legal and identity-theft protection, pet insurance, and wellness discounts. Optional programs can include student-loan and home-purchase support, plus family care resources and expert medical services.
