AI Research Scientist, Text Data Research - MSL

Position: AI Research Scientist, Text Data Research - MSL FAIR
Meta is seeking AI research scientists to help us build the data foundation for Meta's most advanced Large Language Models. We're looking for researchers with LLM expertise to join us on working with data at scale and to 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, agent, 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 having the chance to collaborate with researchers and engineers across MSL.

Minimum Qualifications

* Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience

* PhD in Computer Science or a related technical field

* 1+ year of industry research experience in LLM/NLP or related AI/ML models

* Experience owning and/or driving complex technical projects from end-to-end

* Practical experience with pre-training or mid-training data curation for large foundational models and experience working with organic, synthetic, agentic, or reasoning data for LLMs

* Published research in leading peer-reviewed conferences (e.g., NeurIPS, ICML, ICLR, ACL, EMNLP) and/or demonstrated significant industry influence in the field of AI

Preferred Qualifications

* Experience working on frontier-quality/state-of-the-art Large Language Models

* Multiple first-author publications in leading peer-reviewed conferences (e.g., NeurIPS, ICML, ICLR, ACL, EMNLP)

* Hands-on experience with modeling frameworks like Py Torch

* Hands-on experience on SQL and large-scale data handling, with familiarity of frameworks like Spark and Hive

Responsibilities

* 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 agentic data, synthetic data, reasoning data, web parser, coding data, data scaling laws, or datamix optimization

* Lead complex technical projects end-to-end

About Meta

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.
