Meta is seeking research scientists to help us build the data foundation for Meta's most advanced Large Language and Media Models. We're looking for researchers with LLM expertise to work with data at scale and push beyond the data ceiling. Our team contributes to data curation across all stages of LLM development (pre‑training, mid‑training, post‑training) and all domains/modalities (e.g., web, code, image, video, multilingual).

We tackle the hardest challenges at trillion‑scale, including organic data curation, synthetic data generation, agent and interaction data, and frontier paradigms that redefine what’s possible. Based in Meta Superintelligence Labs (MSL) within the Fundamental AI Research Organization (FAIR), you’ll directly contribute to Meta’s frontier models like Llama, while collaborating with researchers and engineers across MSL.

• Collaborate with cross‑functional teams to develop Meta’s next foundational models
• Advance our understanding of data research, such as how to overcome data walls and how best to create synthetic data
• Architect efficient and scalable data curation systems and pipelines
• Fundamentally improve our data velocity across workflows and projects by contributing to the advancement of data tooling
• Execute on high‑priority projects in pre‑training, mid‑training, or post‑training data curation
• Apply specialized expertise in video/image generation, video/image perception, OCR, agentic data, synthetic data, reasoning data, web parser, coding data, data scaling laws, or datamix optimization
• Lead complex technical projects end‑to‑end

• Bachelor’s degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
• PhD in Computer Science or a related technical field
• 4+ years of industry research experience in NLP or CV
• 4+ years as a formal technical lead
• Experience leading major technical initiatives with cross‑functional impact and influencing strategy across multiple teams
• Practical experience with multimodal pre‑training or mid‑training data curation for large language models, media perception, or media generation models
• Published research in leading peer‑reviewed conferences (e.g., ACL, NeurIPS, ICML, ICLR, AAAI, KDD, CVPR, ICCV) and/or demonstrated significant industry influence in the field of AI

• Experience working on frontier‑quality/ state‑of‑the‑art Large Language or Large Media Models
• First‑author publications at top peer‑reviewed conferences (e.g., ACL, NeurIPS, ICML, ICLR, AAAI, KDD, CVPR, ICCV)
• Programming experience in Python and hands‑on experience with frameworks like PyTorch or Spark, or related distributed computing frameworks (Ray, Data Flow)
• Hands‑on experience on SQL and large‑scale data handling, with familiarity of frameworks like Spark and Hive

Meta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and Whats App further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today – beyond the constraints of screens, the limits of distance, and even the rules of physics.
