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)

We are not expecting everything — strong depth in one area is valuable.

• 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
