Research Engineer; Technical Leadership), FAIR Data - Superintelligence Labs

Meta is seeking Research Engineers to help us build the data foundation for Meta's most advanced Large Language and Media Models. We are 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, and post‑training—and across all domains and modalities such as web, code, image, video, and multilingual data.

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 is possible. Based in Meta Superintelligence Labs (MSL) within the Fundamental AI Research Organization (FAIR), you will directly contribute to Meta’s frontier models while collaborating with researchers and engineers across MSL.

• Collaborate with cross‑functional teams to develop Meta’s next foundational models.
• Architect efficient and scalable data curation systems and pipelines.
• Fundamentally improve our data velocity across workflows and projects by advancing data tooling.
• Execute high‑priority projects in pre‑training, mid‑training, or post‑training data curation.
• Apply specialized expertise in video/image perception or generation, OCR, agentic data, synthetic data, multilingual data, reasoning data, web parsing, coding data, data scaling laws, or datamix optimization.
• Lead complex technical projects end‑to‑end.

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

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

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 empowered billions around the world. Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to build the next evolution in social technology. Building with us at Meta helps shape a future that surpasses what digital connection can currently achieve.
