About the role
- Anduril Industries is seeking a Senior Network Infrastructure Engineer to join the Core Network Engineering team.
- The role involves acting as a pillar for core routing, switching, WAN/backbone transport, multi-cloud interconnects, and edge security systems.
- The engineer will consult directly with internal business lines to translate unconventional technical constraints into robust, secure, and multi-tenant network designs.
Responsibilities
- Design, scale, and maintain resilient campus, datacenter, and field-test networks utilizing traditional three-tier and EVPN-VXLAN fabric designs across Arista (EOS) and Cisco (Catalyst/Nexus) platforms.
- Architect, scale, and maintain corporate and datacenter WAN backbone, owning carrier circuit delivery, capacity planning, and turn-up for optical waves, dark fiber, and DIA across colocation and telecom providers.
- Design, provision, and maintain resilient hybrid-cloud transit networks across AWS, Azure, and GCP, including dedicated interconnects, Transit Gateways/VNet Hubs, dynamic BGP peering, and cloud-native routing architectures.
- Develop scalable network standards, reference architectures, and implementation patterns, and participate in architecture reviews.
- Partner with the Senior Network Automation Engineer to drive Network-as-Code workflows leveraging foundational knowledge of Python, Nornir, and Jinja2.
- Partner with the dedicated Wireless/RF Engineer to design, deploy, and maintain campus-wide and field Wi-Fi deployments leveraging Aruba and Juniper Mist platforms with enterprise 802.1X/EAP-TLS authentication.
- Implement, audit, and manage Layer 3–7 security policies, microsegmentation strategies, and site-to-site IPsec tunnels utilizing Palo Alto Networks NGFWs managed globally via Panorama.
- Implement deep-visibility tooling, flow analysis, and streaming telemetry dashboards (Grafana, Prometheus, Syslog) to proactively detect degradation, reduce MTTR, and improve alerting fidelity.
- Act as a final point of technical escalation for critical, intermittent, or high-blast-radius network anomalies, lead post-mortem reviews, and participate in a shared Tier-3 on-call rotation.
- Support, coach, and level-up junior systems administrators and network engineers through runbook authoring, architectural reviews, and pairing sessions.
Requirements
- 8+ years of hands-on experience designing, scaling, and maintaining complex multi-vendor enterprise, backbone, and campus production networks.
- Deep operational mastery of BGP (path selection, community manipulation, convergence optimization) and OSPF.
- Demonstrated production experience deploying and troubleshooting EVPN-VXLAN fabrics.
- Proven experience designing multi-tenant network architectures (VRFs, dynamic segmentation, macro- and micro-segmentation).
- Expert-level packet analysis skills (tcpdump, Wireshark) for diagnosing subtle transit failures, MTU/fragmentation mismatches, and asymmetric routing.
- Experience working directly with carriers and telecom providers to scope, order, cross-connect, turn up, and test high-bandwidth transport circuits (10G/100G Waves, dark fiber, DIAs).
- Proven track record provisioning and troubleshooting cloud-native networking components and dedicated connectivity (AWS Direct Connect, Azure ExpressRoute, GCP Cloud Interconnect, VPC/VNet peering, Transit Gateways).
- A strong programmatic mindset with the ability to read, review, and write foundational Python, along with working familiarity with automation ecosystems (Nornir, Jinja2, Netmiko) and REST APIs.
- Expert-level configuration, architecture, and troubleshooting experience across Arista Networks (EOS, CloudVision, spine-and-leaf designs), Cisco Systems (Catalyst 9k, Nexus), Palo Alto Networks (NGFW, Panorama), and Enterprise Wireless (Juniper Mist, Aruba).
- Eligible to obtain and maintain an active U.S. Secret security clearance.
Preferred qualifications
- Senior or Expert-level industry certifications (CCNP/CCIE, JNCIP/JNCIE, PCNSE, or Arista ACE).
- Certifications in public cloud networking (e.g., AWS Certified Advanced Networking - Specialty, Azure Network Engineer Associate).
- Experience operating within regulated or compliance-driven environments (e.g., ITAR, EAR, NIST 800-171, CMMC).
- Experience with Network Source-of-Truth platforms (NetBox, Nautobot).
- Hands-on experience with modern observability platforms (Telegraf, InfluxDB, Prometheus, Grafana, OpenConfig/gNMI).
