Senior Network Engineer
Routers, switches, firewalls, and the invisible architecture that moves every packet from point A to point B without users ever thinking about it.
What it's like to be a Senior Network Engineer
As a Senior Network Engineer, you design, implement, and maintain the network infrastructure โ routers, switches, firewalls, wireless systems, and WAN connections โ that enables organizational communication and application delivery. The senior title means you're making architectural decisions about network topology, leading complex implementations, and providing expert-level troubleshooting.
Your day alternates between design work and operational support. You might design a network architecture for a new office location, then configure BGP peering with a new ISP, then troubleshoot intermittent packet loss affecting a critical application, then evaluate SD-WAN solutions for branch connectivity. You need deep knowledge of routing and switching protocols, network security, and the vendor-specific skills (Cisco, Juniper, Arista, Palo Alto) relevant to your environment.
The challenge is balancing stability with evolution. Networks must be reliable โ changes carry risk, and outages are visible. But technology evolves โ SD-WAN, zero-trust architecture, cloud connectivity โ and standing still means falling behind. You need the judgment to introduce changes carefully while keeping the network running for users who expect it to just work.
