Research Engineer at Meta
Paris, Ile-de-France
Summary
🤩
Rockstar🎓
Top SchoolJérémy Rapin is a research engineer at Meta AI with 11 years of experience building data and training infrastructure for large-scale ML research. He is a founding maintainer of Nevergrad and the original creator of submitit, contributing deep expertise in optimization, job scheduling on Slurm, and robust backend tooling. His background spans applied mathematics and signal processing (PhD), and he led production-grade deep learning efforts in medical AI that achieved regulatory milestones like CE/FDA pathways. Comfortable bridging research and production, he has shipped tested Python libraries, designed structured configuration and optimization plugins for Hydra, and improved cluster automation. Based in Paris, he pairs rigorous academic training with hands-on systems engineering, often working on the low-level algorithmic details that make large ML experiments reproducible and scalable. A less obvious strength is his track record of turning niche research code into widely used open-source infrastructure relied on across Meta and the broader ML community.
