These skills ensure reliable and secure network operations, minimizing downtime and supporting organizational productivity.

What are Network Engineers?

Network Engineers are IT professionals who design, implement, manage, and troubleshoot computer networks within an organization. They work with hardware and software to ensure networks operate efficiently and securely, supporting both local area networks (LANs) and wide area networks (WANs). Network Engineers are responsible for tasks such as configuring network devices, monitoring network performance, upgrading systems, and resolving connectivity issues. They often work closely with other IT staff to support business operations and maintain network security.

What are some common challenges Network Engineers face when troubleshooting network issues, and how can they effectively address them?

Network Engineers often encounter challenges such as identifying the root cause of connectivity problems, dealing with legacy equipment, or managing network congestion. Effective troubleshooting requires a systematic approach—using network monitoring tools, analyzing logs, and methodically isolating potential failure points. Collaborating closely with other IT teams, staying up-to-date with evolving technologies, and documenting solutions also help ensure quick and efficient resolution of network issues.

Job description

Hybrid 2-3 days a week on site after first 6 months getting up to speed on site every day.
Position Summary
We are seeking a seasoned Network Engineer to design, implement, optimize, and support a complex, multi-site enterprise network. This role is responsible for maintaining highly available, secure, and scalable infrastructure across routing, switching, SD-WAN, wireless, and firewall platforms.
The right person is hands-on, comfortable in production, capable of architectural thinking, and able to partner with infrastructure, security, and cloud teams to keep the business running.
This is not an entry-level operations job. We need someone who can own the network.
What You'll Do
  • Design, deploy, and maintain enterprise routing and switching environments.
  • Lead configuration, optimization, and lifecycle management of Cisco, Juniper, and Meraki platforms.
  • Implement and support SD-WAN solutions including policy design, traffic engineering, and failover strategies.
  • Manage next-generation firewall technologies, VPNs, segmentation, and secure connectivity.
  • Monitor performance, troubleshoot outages, and drive root-cause analysis for complex incidents.
  • Participate in network architecture planning, capacity forecasting, and modernization efforts.
  • Create and maintain network diagrams, standards, and operational documentation.
  • Collaborate with cybersecurity, server, cloud, and application teams to ensure resilient integrations.
  • Provide escalation support for high-priority production issues.
  • Mentor junior engineers and contribute to operational maturity and best practices.
Technology Environment
  • Routing & Switching: Cisco, Juniper
  • Access & Branch Networking: Cisco Meraki
  • SD-WAN: Silver Peak (HPE Aruba)
  • Firewalls & Security: Palo Alto
  • Protocols: BGP, OSPF, EIGRP, VLANs, STP, VPN technologies
  • Monitoring & Tools: SNMP, NetFlow, packet capture, enterprise monitoring platforms
What We're Looking For
  • 5+ years of progressive experience in network engineering.
  • Deep expertise in enterprise routing and switching.
  • Strong hands-on background with Palo Alto firewalls.
  • Proven experience implementing or supporting SD-WAN.
  • Ability to troubleshoot across layers (routing, security, transport).
  • Experience working in distributed, multi-location environments.
  • Comfortable leading projects and making architecture recommendations.
  • Strong documentation and communication skills.
