About Mistral
At Mistral AI, we build high-performance, open, and efficient AI systems designed to power the next generation of applications. Our infrastructure combines large-scale distributed systems, cloud platforms, and HPC environments to support cutting-edge research and production workloads.
We are a collaborative, low-ego, and highly technical team, operating across Europe, the US, and beyond. As we scale rapidly, we are building the foundational infrastructure to support thousands of nodes and petabyte-scale systems.
Join us to be part of a pioneering company shaping the future of AI. Together, we can make a meaningful impact.
About the Role
We are looking for Systems Engineers / System Administrators to help design, operate, and scale the infrastructure behind Mistral’s AI platforms.
This is a hands-on, hybrid role combining:
Systems administration (operating and troubleshooting large-scale Linux environments)
Systems engineering (automation, scalability, and performance improvements)
You’ll work closely with infrastructure, HPC, and research teams to ensure our clusters and platforms run reliably at scale.
What You’ll Work On
Core Systems Operations
Operate and maintain large-scale Linux environments (bare metal, clusters, cloud)
Monitor system health, troubleshoot incidents, and ensure high availability
Support production and research workloads across multiple environments
Scaling Infrastructure
Help scale clusters toward hundreds to thousands of nodes
Work on systems handling petabyte-scale storage
Improve performance, reliability, and resource utilisation
Automation & Engineering
Automate operational tasks using tools like Python, Bash, Ansible, or Terraform
Improve deployment, provisioning, and system lifecycle management
Contribute to system design and architecture decisions
Cross-Functional Collaboration
Work closely with:
HPC / infrastructure teams
Platform / DevOps engineers
Research teams
Act as a bridge between users and infrastructure
What We’re Looking For
Must-have
Strong Linux systems administration experience (core requirement)
Experience working in large-scale environments:
HPC clusters or cloud infrastructure
Experience with Job schedulers (e.g. Slurm)
Solid troubleshooting skills across systems, hardware, and networks
Nice-to-have (any of these)
Containers / orchestration (e.g. Kubernetes)
Storage systems (e.g. Ceph, Lustre, NFS)
Networking fundamentals (Ethernet; InfiniBand is a plus)
Infrastructure as Code / automation tooling
GPU or AI/ML experience
Profile We Value
Pragmatic problem solver who can operate in fast-scaling environments
Comfortable working across multiple domains (“Swiss army knife” mindset)
Able to go deep in one area while learning others
Low-ego, collaborative, and hands-on
