Job summary

Mistral is seeking a senior engineering leader to manage and grow the Cloud Platform team. You will split time between architecture decisions and hands-on work, guiding a group of engineers building secure, isolated environments for AI workloads.

You will ship high-performance backend systems in Go, own the security boundary, and partner with Product Managers to turn frontier research into practical primitives. Leadership is required from day one.

Qualifications

• 2+ years of real people leadership.
• Deep Linux internals: namespaces, cgroups, seccomp, virtualization.
• Shipped production systems in Go. Not dabbled. Shipped.
• Understanding network isolation at the packet level - not just firewall rules.
• 8+ years building backend or infrastructure systems.
• Partnered with product, design, and business teams to ship software that reached real users.
• A low-ego, team-first mindset. We care less about your exact domain and more about whether you are the kind of technical force other engineers want to work alongside.

Responsibilities

• Build the isolation layer: microVMs or containers, namespaces, cgroups, seccomp, snapshot and restore.
• Own the security boundary. Customers run code they didn't write and can't fully trust - your systems make that safe.
• Scale to fleets: creation latency, density, and lifecycle management for thousands of concurrent environments.
• Write Go alongside your team and own the architecture and the hardest implementation decisions.
• Grow the engineers, not just the software - set the standard for ownership and coach people past their comfort zone.
• Own people management for the team: hiring, performance, growth paths, and honest feedback.
• Partner with Product Managers to turn frontier research needs into shippable primitives.
