Mirantis is seeking a Senior Network Engineer to join its IT team in a hands-on role spanning two critical areas: the networking infrastructure for internal AI labs and broader company network operations. This is the second dedicated networking role on the team, working alongside an existing network engineer in Europe to scale the function as the company invests heavily in AI compute infrastructure.
The role is based in Silicon Valley with regular on-site presence required at local datacenter and colocation facilities. As Mirantis builds out AI compute environments, the lab networks have become critical shared infrastructure that engineering groups across the company consume as tenants. The networking team's mandate is to deliver high-throughput fabric for GPU and compute-intensive workloads, clean segmentation between tenants, and reliable connectivity to corporate and cloud environments. This is fundamentally a hardware-, networking-, and architecture-focused role—building and operating the underlying infrastructure rather than the AI/ML applications running on top.
Key responsibilities include:
**AI Labs Network Architecture & Operations:** Design, build, and operate the network fabric for internal AI labs, including high-throughput switching for GPU workloads with multi-tenant segmentation. Own capacity planning and expansion as demand grows.
**Datacenter & Colocation Infrastructure:** Own physical and logical infrastructure at the Silicon Valley datacenter/colocation facility, including network fabric, rack and cabling standards, cross-connects, and power/port planning. Perform hands-on structured work on-site for buildouts, changes, and troubleshooting. Operate networks at other datacenter locations (including Europe) through contractors or remote-hands services.
**Server & Hardware Support:** Provide hands-on support for server and datacenter hardware—racking, cabling, provisioning, firmware/BMC (iDRAC/iLO) management, and physical troubleshooting. Coordinate third-party contractors and remote-hands services as needed.
**Corporate & Campus Networking:** Share ownership of day-to-day company network operations—offices, LAN/WLAN, remote access, and connectivity between on-prem/colo, corporate, and cloud environments (site-to-site VPN, AWS interconnects, SD-WAN). Bring these environments to a consistent, well-engineered standard.
**Network Security & Segmentation:** Partner with Corporate/Product Security to operationalize network security baselines—firewall policy, ACLs, network access control, least-privilege segmentation, and secure management planes.
**Monitoring, Observability & Capacity:** Implement and maintain network and infrastructure monitoring, alerting, and traffic visibility across labs, datacenter, corporate, and cloud environments. Use data to catch issues early, plan capacity, and inform architecture decisions.
**Standards, Documentation & Automation:** Establish network and infrastructure standards, runbooks, and clear architecture documentation as the function scales. Automate configuration and repetitive operations using IaC and network automation tools.
**Incident Response & On-Call:** Participate in on-call rotation to respond to network and infrastructure incidents. Triage and resolve production issues, perform root cause analysis, and contribute to post-incident reviews.
**Requirements:**
- 5+ years of experience in Network Engineering with networking as the core of your background
- Strong hands-on experience designing and operating switching and routing in datacenter and/or colocation environments—spine/leaf or top-of-rack fabrics, VLANs, VXLAN/EVPN, BGP/OSPF, and structured cabling
- Solid experience with firewalls, ACLs, VPNs (site-to-site and remote access), and network segmentation; vendor experience with Cisco, Arista, Juniper, Palo Alto, or Fortinet
- Comfortable working physically on-site in a datacenter—racking, cabling, cross-connects, and troubleshooting at the hardware level—and coordinating remote-hands or contractor work
- Working knowledge of server hardware—provisioning, firmware/BMC management (iDRAC/iLO), and physical troubleshooting—with willingness to own the compute layer alongside the network
- Experience with cloud and hybrid connectivity (AWS interconnects, VPN, SD-WAN) and how on-prem, colo, and cloud environments fit together
- Familiarity with network monitoring and observability (SNMP-based tooling, NetFlow, Prometheus/Grafana, or similar) and using it for capacity planning
- Scripting/automation and network automation or Infrastructure as Code (Python, Bash, Ansible, Terraform, or similar)—hands-on experience is a strong plus; alternatively, demonstrated ability and strong desire to pick these up quickly
- Prior experience with on-call rotations and incident management
- Good understanding of network and infrastructure security fundamentals—least-privilege access, secure management planes, and segmentation
- High-throughput and GPU/AI cluster networking (RDMA/RoCE, InfiniBand, high-speed Ethernet)—existing experience is a strong plus; alternatively, strong desire and ability to ramp up quickly
- Experience with SOC 2, ISO 27001, or similar compliance frameworks is a plus
- Strong communication skills and ability to document standards, runbooks, and architectural decisions clearly
