Network Automation Engineer - Data Center Fabrics & EVPN

Mistral; Amsterdam; On-site; EUR 90,000 - 130,000; Full time

Job summary

Mistral seeks a Software Engineer, Network Automation – Data Center Fabrics to design and build systems for operating large-scale networks in our data centers. You will apply deep networking expertise to leaf-spine architecture, automation, testing, and production troubleshooting across Ethernet switching, IP routing, BGP, EVPN/VXLAN, and VRFs.

Go and Kubernetes experience are helpful but not required; strong fundamentals and network automation matter more.

Qualifications

• Deep hands-on experience with Ethernet switching, IP routing, BGP-based leaf-spine fabrics, EVPN/VXLAN, and VRF-based multitenancy.
• Strong judgment around fabric underlay and overlay design, scale, convergence, isolation, and failure modes.
• Experience building or operating production network automation, including desired state, idempotency, concurrency, observability, and recovery.
• Strong software-engineering fundamentals in a general-purpose language (Go preferred) and ability to design, test, debug, and review production systems.
• Experience with southbound network APIs and structured configuration (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/EVPN state, telemetry, logs, and packet captures.

Responsibilities

• Design and evolve leaf-spine underlays, EVPN/VXLAN overlays, and tenant connectivity for multi-tenant AI infrastructure.
• Translate data-center fabric requirements into APIs, data models, validation, and automation.
• Build reliable control-plane software that reconciles desired and observed network state.
• Design safe change workflows with validation, dry runs, atomic updates, observability, and failure recovery.
• Integrate with data-center switch OS and management APIs while maintaining vendor-neutral abstractions.
• Participate in on-call rotation, troubleshoot incidents, restore service, and turn root causes into improvements.
• Review designs and code, explain networking trade-offs, and raise network engineering quality.
• Develop lab and production tests and turn operational lessons into better software and architecture.
