About the job

Mistral AI is seeking a Research Engineer focused on Data Infrastructure to architect and build the backbone of our frontier model training and fine-tuning ecosystem. This role involves designing and scaling massive compute fleets and storage systems for high performance and scalability, with a vision towards exabyte-scale architecture. You will contribute to a strategic transition from legacy scheduling to modern orchestration, implementing sophisticated multi-cluster orchestration and cloud-bursting capabilities. The position requires full lifecycle ownership, from architecting migrations away from legacy orchestrators to implementing production-grade pipelines and participating in on-call rotations for critical training jobs.

Responsibilities

  • Build and scale massive distributed compute and storage systems.
  • Architect and maintain multi-cluster orchestration layers for optimized workload placement.
  • Design and architect transitions to modern storage formats for exabyte-scale fine-tuning datasets.
  • Contribute to the development of the internal training platform across Kubernetes and SLURM environments.
  • Implement and manage metadata and lineage systems for data and model pipelines.
  • Manage cloud-native deployments using modern workflows to ensure scalability, reliability, and efficiency.

Requirements

  • 4+ years of experience in Data Infrastructure, MLOps, or Infrastructure Engineering.
  • Experience or strong interest in supporting foundational compute and storage platforms.
  • Proficiency in Python and experience with modern, columnar storage standards.
  • Well-versed in Kubernetes-native tooling and debugging large-scale distributed systems.
  • Experience building and operating scalable, reliable, and secure systems.
  • Comfort with ambiguity and challenges of building high-scale infrastructure in a rapid-growth AI environment.

Benefits

  • Competitive cash salary and equity
  • Daily lunch vouchers (France)
  • Monthly contribution to a Gympass subscription (France)
  • Monthly contribution to a mobility pass (France)
  • Full health insurance for you and your family (France)
