Principal Network Engineer

We are looking for a Principal Network Engineer who thrives on solving complex routing problems and designing resilient network architectures. This is a hands-on engineering role where you will work on challenging real-world networks, lead advanced troubleshooting efforts, and help shape the technical direction of our infrastructure.

You will be part of a highly collaborative engineering team responsible for building and supporting networks that serve a growing customer base. This role offers the opportunity to work deeply with BGP driven WAN architectures, Fortinet and Cisco platforms, and multi-site routing environments while mentoring other engineers and influencing engineering standards across the organization.

If you enjoy digging into routing tables, analyzing packet flows, and solving problems others cannot, this role will give you the space and autonomy to do that work. We are also big believers in teamwork and shared support, so you will be working alongside other engineers who collaborate closely, help each other solve tough problems, and take collective ownership of the network.

What Makes This Role Different

This position is more than just another senior engineering role. As a Principal Engineer, you will help shape how our networks are designed and operated. You will:

• Review and guide major network architecture decisions
• Lead troubleshooting during critical outages
• Establish engineering standards and best practices
• Mentor engineers and help grow the team’s technical depth
• Influence technical strategy and vendor platform decisions

Your expertise will directly impact how our network evolves as we continue to scale, supporting the connectivity that enables K-12 schools to deliver education to students every day.

Responsibilities

• Design and implement complex Layer 3 network architectures
• Engineer and troubleshoot BGP based WAN and multi-site routing environments
• Perform advanced configuration and troubleshooting using CLI on Fortinet FortiGate and Cisco platforms
• Architect routing strategies involving:
• Route redistribution
• Route filtering and prefix lists
• AS path prepending and local preference
• BGP communities and traffic engineering
• ECMP and multipath routing
• Diagnose protocol and packet level issues using CLI tools including routing analysis, debugs, and packet captures
• Design high availability network architectures that maintain service continuity
• Troubleshoot traffic flow issues involving routing and firewall policy interactions
• Lead technical response during high severity incidents
• Produce clear documentation and network diagrams to support engineering operations
• Mentor engineers and help elevate the overall technical capabilities of the team

Education and/or Experience Requirements

• 7+ years hands-on routing experience
• Deep understanding of BGP (iBGP, eBGP, route reflectors, filtering, path selection)
• General understanding of OSPF
• Strong grasp of routing theory (not just configuration memorization)
• Ability to read and interpret routing tables and protocol states quickly CLI Mastery (Mandatory)
• Advanced CLI configuration and troubleshooting on Fortinet FortiGate platforms
• Ability to perform live troubleshooting in production environments via CLI

Networking Fundamentals

• Deep knowledge of TCP/IP
• Strong subnetting and summarization skills
• VLANs, trunking, and STP fundamentals
• NAT and policy-based routing
• VPN technologies (IPSec preferred)

Preferred Qualifications

• Fortinet NSE 4/5/7 or equivalent experience
• Experience with multi-ISP failover designs
• Experience serving K-12, government, or MSP environments
