Network Engineer

Hadrian Automation • Torrance, CA

70d • $189,000 - $227,000 • Hybrid

About The Position

Hadrian is looking for a Senior Network Engineer to take ownership of the design, architecture, and reliability of network infrastructure across their data center, campus, multi-site, and cloud environments. This role involves defining network standards, architecting connectivity from the data center fabric to the factory floor and office campus, and leading new site deployments from design to production. The engineer will serve as the technical authority on networking, collaborating with infrastructure, IT, security, and operations teams to create scalable topologies, implement automation through Infrastructure-as-Code (IaC), and ensure the reliability of a 24/7 manufacturing environment. The ideal candidate possesses comprehensive knowledge across all network layers and environments (data center, campus, wired, wireless, WAN, cloud), combines deep expertise with strong architectural judgment, and develops scalable systems and standards.

Requirements

• 8+ years in network engineering, operations, or infrastructure, including senior design and architecture ownership
• Deep expertise in TCP/IP, routing, switching, wireless, VLANs, 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

Nice To Haves

• CCNP, CCIE, JNCIP/JNCIE, or equivalent advanced certifications
• Hands-on Juniper Mist (Mist AI, Wired Assurance, WAN Assurance, Marvis) for campus operations and AIOps
• BGP at scale: route reflectors, communities, traffic engineering, multi-provider edge
• EVPN/VXLAN fabrics in data center and/or campus (BGP EVPN, symmetric/asymmetric IRB, VRF multi-tenancy, ESI-LAG, DCI)
• Route and overlay hardening (RPKI, prefix filtering, max-prefix limits, BFD)
• Multi-vendor fabric platforms and controllers (Juniper Apstra, Arista CloudVision, Cisco NX-OS/ACI)
• Deep Juniper (EX/QFX, SRX, Mist) and Palo Alto firewall experience
• AWS/Azure networking depth (VPC, Direct Connect, VPN Gateway, Transit Gateway, ExpressRoute) with BGP-based hybrid routing
• Kubernetes networking (CNI, ingress, service mesh, BGP load balancing like MetalLB/Calico)
• ISP relationship and circuit provisioning management at scale
• Structured cabling and low-voltage program leadership
• Facility systems experience (cameras, access control, IoT)
• Experience with designing a high-availability, 24/7 production environment design
• Mentoring admins, engineers or technical lead experience

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)

Benefits

• Medical, dental, vision, and life insurance plans for employees
• 401k
• Relocation support may be provided for certain situations, based on business need.
• Flexible vacation policy
• Equity
