About the Role

We are seeking a Senior Network Engineer to manage and enhance our hybrid network infrastructure, encompassing physical offices, distributed sites, and AWS cloud connectivity. This role involves hands-on management of network hardware, cloud networking, and automation through infrastructure-as-code.

Responsibilities

  • Manage, monitor, and maintain office, site, and distributed network infrastructure including Meraki switches, wireless access points, Palo Alto firewalls, Starlink links, ISP connections, and site-to-site VPN.
  • Design and deploy office and site networks, covering switching, routing, VLAN segmentation, wireless coverage, and secure remote connectivity.
  • Tune wireless deployments, including RF planning, capacity modeling, channel optimization, and troubleshooting roaming and interference issues.
  • Configure and harden Palo Alto firewalls and VPNs, managing security policies, NAT, IPSec tunnels, Global Protect, and Panorama-based centralized management.
  • Troubleshoot complex Layer 1 through Layer 7 issues across physical and logical stacks using diagnostic tools like Wireshark, tcpdump, ThousandEyes, Fiddler, and nmap.
  • Maintain monitoring and alerting systems such as PRTG, Nagios, Grafana, New Relic, and ThousandEyes.
  • Serve as the technical escalation point for network incidents, owning production outages from alert to root cause analysis and post-incident improvements.
  • Participate in on-call rotation.
  • Maintain the multi-VPC AWS environment, including VPCs, subnets, route tables, Security Groups, NACLs, and VPC peering.
  • Operate Transit Gateway, Direct Connect, and Site-to-Site VPN connectivity between AWS and physical sites.
  • Manage Route 53 public and private zones, DNS forwarders, and hybrid name resolution.
  • Support and tune AWS Load Balancers (ALB, NLB) for application teams.
  • Troubleshoot connectivity issues spanning AWS, on-prem, and Kubernetes-based microservices environments.
  • Use Terraform (and Terragrunt where applicable) to deploy and manage networking resources like VPCs, firewall rules, DNS, routing, and Security Groups.
  • Contribute to and maintain CI/CD pipelines for network changes through GitHub workflows, peer review, and automated validation.
  • Build tools and scripts (Python, Bash) to automate repetitive operational tasks.
  • Prevent configuration drift through code-first network management.
  • Configure, harden, and patch network devices and services according to security best practices.
  • Monitor security alerts, investigate incidents, and coordinate remediation with the security team.
  • Validate firewall changes for least-privilege and operational impact before production deployment.
  • Maintain network documentation, topology diagrams, runbooks, and change records.
  • Partner with engineering teams to troubleshoot network design and connectivity in AWS and Kubernetes environments.
  • Provide technical consulting on network architecture decisions.
  • Communicate clearly with technical and non-technical stakeholders during incidents, changes, and planned maintenance.
  • Work with IT leadership to evaluate new products, vendor roadmaps, and infrastructure investments.
  • Backup the systems engineering team for Windows and Linux server administration when network issues overlap with server or application behavior.

Requirements

  • 8+ years of progressively senior network engineering experience with deep hands-on ownership of physical network infrastructure (switching, routing, wireless, firewalls).
  • 5+ years of experience administering enterprise wireless and switching platforms, preferably Cisco Meraki, including Dashboard operations, switch stacks, VLAN design, and RF tuning.
  • Hands-on Palo Alto firewall experience including security policy design, NAT, IPSec/SSL VPN, and centralized management through Panorama. Familiarity with Strata Cloud Manager is a plus.
  • Expert-level knowledge of enterprise network protocols: BGP, OSPF, STP, VLANs, IPSec, DNS, SNMP, DHCP, and the ability to troubleshoot each from the command line.
  • Strong AWS networking experience: VPC architecture, Transit Gateway, Direct Connect, Site-to-Site VPN, Security Groups, Route 53, and VPC peering. Ability to design and operate a multi-VPC environment connected to physical sites.
  • Proficiency in Terraform for production network infrastructure. Experience with Terragrunt, CloudFormation, or Ansible is a plus.
  • Methodical, command-line-first troubleshooting skills, including reading packet captures and using tools like tcpdump and traceroute.
  • Solid Linux fundamentals, including comfort in a shell and understanding of OS-network interaction.
  • Awareness of microservices and Kubernetes networking, including troubleshooting service-to-service connectivity, DNS, ingress, and routing in container-based environments.
  • Strong incident ownership experience, having led major production network outages from detection through root cause to long-term fix.
  • Strong written and verbal communication skills for documentation, stakeholder updates, and post-incident reviews.
  • Comfortable working in the Eastern Time Zone.
  • Ability to travel up to 25% to office sites.
