🚀 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. See more about our culture on https://mistral.ai/careers.
💡 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
