About Mistral Mistral provides full-stack AI solutions: from frontier models to developer tools, applications, and compute. Our diverse workforce thrives in competitive environments and is committed to driving innovation. The team Mistral is building a sovereign AI cloud for Europe. Our customers in finance, healthcare, and the public sector run frontier models on European-jurisdiction infrastructure, and the Cloud Platform team builds the systems that make that possible — compute orchestration, Kubernetes, bare metal, storage, networking, and the datacenter fleet that runs it all. We run it all on our own metal, our own network, our own datacenters — which means when something breaks, the fix is ours to write. You will design and ship the layer every sovereign AI deployment depends on and shape the team building it. Early on you will be deliberately hands-on, because there is no one else to solve the hardest problems — but hiring your first engineers, coaching them, and setting their growth paths starts immediately, not later. If you are looking for a senior IC role, this is not it. You will be the founding Engineering Team Lead for storage on our cloud. Block, filesystem, and object storage for training runs, sandboxed workloads, and general compute: you decide what we build, what we buy, and how it adds up to storage our customers can bet a business on. The ones that matter most we write ourselves in Go — S3-compatible object storage, tiering, backup and recovery,



caching layers that put cold data on cheap spinning disks. As the team grows, the balance shifts toward people leadership, and you decide how fast. You will own capacity planning across datacenters and the architecture that keeps data durable when disks, networks, and entire sites fail. Storage is a strategic bet for this org: the team you build and the calls you make will define how a gigawatt of European compute stores its data. Stand up the storage stack — block, file, object — for training, sandbox, and general compute workloads. Own the data plane: allocation, duplication, tiering, backup and recovery, S3-compatible APIs. Build the team from zero: make the first hires, onboard and coach them, own performance and growth paths, and set the standard for ownership. Deep distributed-systems fundamentals: durability, consistency, replication, erasure coding, failure domains. ~ Systems engineers coming from C++ or Rust who are ready to write Go daily should still talk to us. ~ 8+ years building backend or infrastructure systems. ~ You have partnered with product, design, and business teams to ship software that reached real users. ~ Benefits vary by country and may include healthcare coverage, parental leave, retirement plans, relocation support, wellness programs, meal and transportation allowances, and other location-specific perks.
