Research Engineer, Media Data Research - MSL FAIR

Meta is seeking AI research engineers to help us build the data foundation for Meta's most advanced Large Language and Media Models. We're looking for engineers with LLM/LMM 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/LMM development (pre-training, mid-training, post-training) and all domains/modalities (image, video, agent, media perception and generation). We are tackling complex challenges at trillion-scale, including organic data curation, synthetic data generation, agent and interaction data, and frontier paradigms that redefine what is possible.
