Mirantis is seeking a Senior Network Engineer to join its IT team in Silicon Valley. This is the second dedicated networking role on the team, working alongside an existing network engineer in Europe to scale a function that has grown beyond single-person capacity.
The role spans two critical areas: (1) the networking infrastructure underpinning Mirantis's internal AI labs, where engineering groups across the company consume compute environments as tenants, requiring high-throughput fabric for GPU and compute-intensive workloads, clean tenant segmentation, and reliable connectivity to corporate and cloud environments; and (2) the broader company network infrastructure including offices, datacenter/colocation presence, cloud interconnects, and remote access.
Key responsibilities include:
**AI Labs Network Architecture & Operations:** Design, build, and operate the network fabric for internal AI labs—high-throughput switching for GPU workloads with segmentation for multi-tenant use. 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. Provide regular on-site presence for buildout, 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, either on-site or coordinated through third-party contractors.
**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 to catch issues early and inform architecture decisions.
**Standards, Documentation & Automation:** Establish network and infrastructure standards, runbooks, and architecture documentation as the function scales. Automate configuration and repetitive operations using Infrastructure as Code and network automation.
**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
