Job summary

Hadrian is building autonomous factories to reindustrialize America. We are seeking a Senior Network Engineer to own design, architecture, and reliability of network infrastructure across data centers, campus, multi-site, and cloud environments.

You will define standards, drive automation through IaC, and lead site bring-ups from design to production. The role requires deep network expertise across TCP/IP, routing, switching, and cloud networking, with hands-on experience in VXLAN/EVPN fabrics

Qualifications

• 8+ years in network engineering, operations, or infrastructure.
• Deep expertise in TCP/IP, routing, switching, wireless, DNS, and DHCP at scale.
• Full‑stack network experience: data center, campus, and multi‑site, wired and wireless.
• Strong production experience with BGP and OSPF (route policy, redistribution, filtering, path selection).
• Hands‑on with overlay networks, especially VXLAN/EVPN fabrics and spine‑leaf.
• Campus LAN and enterprise wireless design, ideally with cloud‑managed platforms like Juniper Mist.
• Solid high‑availability and redundancy design (BGP/OSPF failover, HSRP/VRRP, path resiliency).
• Proven multi‑site enterprise network experience.
• Strong SD‑WAN architecture and implementation experience.
• Hands‑on VPN experience (GlobalProtect, IPsec site‑to‑site, remote access).
• Cloud networking design (AWS and/or Azure), including hybrid connectivity and routing.
• Proficiency with IaC tools (Git, Terraform, Ansible, Pulumi, CICD, etc.)
• Track record leading complex network projects to completion.
• Strong operational mindset that balances speed and reliability.

Responsibilities

• Own network architecture across data center, campus, multi‑site, and cloud, setting standards and reference designs that scale
• Lead new site bring‑ups from topology design and capacity planning through production handoff
• Architect routing and switching in a scalable fashion, including route policy, redistribution, and segmentation
• Design and operate BGP for internet edge, multi‑homing, and cloud interconnects (peering, filtering, path selection, failover)
• Build VXLAN/EVPN fabrics: spine‑leaf, BGP EVPN control plane, VTEPs, L2/L3 VNIs, and DCI for scalable segmentation and multi‑tenancy
• Design and operate campus networks (access, distribution, core vs clos), wired and wireless, across offices and the factory floor
• Run cloud‑managed wired and wireless with Juniper Mist (Mist AI, Wired Assurance, WAN Assurance) for AI‑driven operations and troubleshooting
• Implement SD‑WAN and overlay technologies (GRE/IPsec/SASE) to connect sites, cloud, and remote users
• Design highly‑available connectivity: VPNs (GlobalProtect, IPsec, remote access), first‑hop redundancy (HSRP/VRRP), switch clustering
• Architect cloud networking across AWS and Azure (VPC/VNet, transit, peering, hybrid, BGP over Direct Connect/ExpressRoute)
• Drive network automation with Infrastructure‑as‑Code (IaC) for provisioning, configuration, and change management
• Set standards for monitoring, observability, documentation, and operational runbooks
• Lead root‑cause analysis across routing, overlay, wireless, DNS, and performance issues
• Manage ISP and telecom relationships for circuits, redundancy, and escalations
• Coordinate low‑voltage vendors and structured cabling for facility and data center build‑outs
• Guide connectivity for facility systems (cameras, access control, IoT) and corporate Wi‑Fi
• Mentor IT and infrastructure teammates and review designs and changes
• Join on‑call rotations, incident response, maintenance windows, and help mature escalation processes
• Support Kubernetes and container networking (CNI, ingress, service networking)
