About Mistral

Mistral provides full-stack AI solutions, partnering with enterprises to tackle complex challenges in high-stakes sectors such as finance, manufacturing, defense, healthcare, and the public sector. Our dynamic and collaborative team is passionate about AI's transformative potential, with a diverse workforce distributed across Europe, North America, Asia, and the Middle East.

The Role

As a Software Engineer focusing on Network Automation for Data Center Fabrics, you will design and build systems for managing large-scale networks within our data centers. Your deep networking expertise will be applied to leaf-spine architecture, automation, testing, and troubleshooting production issues across Ethernet switching, IP routing, BGP, EVPN/VXLAN, and VRFs.

Responsibilities

• Design and evolve leaf-spine underlays, EVPN/VXLAN overlays, and tenant connectivity for multi-tenant AI infrastructure.
• Translate data center fabric requirements into clear APIs, data models, validation, and automation.
• Build reliable control-plane software that aligns desired and observed network states.
• Design safe change workflows with validation, dry runs, atomic updates, observability, and recovery.
• Integrate with data center switch operating systems and management APIs while maintaining vendor-neutral abstractions.
• Participate in on-call rotations, troubleshoot network incidents, restore services, and implement improvements based on root causes.
• Review designs and code, explain networking trade-offs, and enhance network engineering quality across the organization.
• Develop lab and production tests, turning operational lessons into improved software and architecture.

Requirements

• Deep hands-on experience with Ethernet switching, IP routing, BGP-based leaf-spine fabrics, EVPN/VXLAN, and VRF-based multitenancy.
• Strong judgment regarding fabric design, scale, convergence, isolation, and failure modes.
• Experience in production network automation, including desired state, idempotency, concurrency, observability, and recovery.
• Strong software engineering fundamentals in a general-purpose language, with willingness to work in Go.
• Experience with southbound network APIs and structured configurations (REST, gNMI/OpenConfig, NETCONF).
• Hands-on experience with major data center network operating systems (Cumulus Linux, Arista EOS, SONiC, Junos, NX-OS).
• Strong diagnostic skills using routing and EVPN state, packet captures, telemetry, and logs.
• Clear communication and a collaborative approach to technical leadership.

Nice to Have

• Experience with Go code, Kubernetes controllers, operators, CRDs, reconciliation, or Kubebuilder.
• Familiarity with physical or simulated network labs (containerlab, NVIDIA Air, EVE-NG, GNS3).
• Experience with high-performance Ethernet, RoCE, InfiniBand, HPC, or large-scale GPU infrastructure.
