About the role

NVIDIA is seeking a Senior Scientist to contribute to the development of synthetic data generation for training large language models like Nemotron. The ideal candidate will work on open-source libraries within the NVIDIA NeMo ecosystem, focusing on text, code, structured, and multimodal data.

Responsibilities

• Build synthetic data generation pipelines using LLM-based methods and automated quality evaluation.
• Advance multimodal synthetic data generation, including image, document, video, and audio.
• Design and maintain open-source libraries and SDKs with clean APIs and strong documentation.
• Drive software excellence with modern tooling, architecture based on configuration, and professional Git/CI-CD.
• Publish original research at top machine learning and AI conferences to maintain NVIDIA's technical leadership.
• Mentor interns and junior researchers to develop technical growth within the team.

Requirements

• PhD in Computer Science, Machine Learning, Statistics, or a related field, or equivalent experience.
• Research background of 3+ years in synthetic data generation, generative modeling, multimodal machine learning, or related areas.
• Deep technical understanding of LLMs, data shaping during pre- and post-training, and inference frameworks such as vLLM or TGI.
• Proven track record of developing or maintaining software libraries used by a broad developer community.
• Strong publication record at premier venues such as NeurIPS, ICML, ICLR, ACL or similar.

Qualifications

• Open-source contributions in ML or data tooling.
• Experience with multimodal generation or understanding (vision-language, document AI, video, or audio).
• Experience generating data for agentic, tool-use, or reinforcement-learning post-training.
