Core Competencies: * Hardware: Deep experience with Cisco ISR/ASR routers, Catalyst switches, Juniper MX/EX series, and Meraki MS/MX stacks. * Protocols: Proficiency in TCP/IP, IPv4/IPv6, BGP, OSPF, EIGRP, and SD-WAN architectures. * Network Analysis: Experience with packet-level analysis using Wireshark to identify latency or jitter issues. * Physical Layer: Familiarity with Fiber Optic standards (GPON/Active Ethernet) and the ability to use an OTDR or Fusion Splicer when necessary. Soft Skills & Requirements * The Technical Consultant: Ability to walk into a Fortune 500 server room and speak as a peer to their Network Architects. * Critical Thinking: A methodical approach to the "broken" circuit-isolating variables from the handoff to the core. * Mobility: Must hold a valid driver's license and be comfortable with daily travel to client locations. * Physical Ability: Must be able to rack heavy enterprise equipment (up to 50 lbs) and work in professional data center environments. ## Description We are looking for a Network Engineer with a strong background in routing and switching to lead our on-site enterprise deployments. This is not a standard "cable tech" role; we need a Cisco-certified professional who can bridge the gap between physical infrastructure and complex logical networking. You will be the technical authority on-site, responsible for configuring, troubleshooting, and maintaining high-capacity circuits for our most critical business clients., * Advanced L2/L3 Troubleshooting: Resolve complex connectivity issues involving BGP, OSPF, VLAN tagging (802.1Q), and STP. * Enterprise Deployment: Lead the installation and CLI-based configuration of Cisco, Juniper, and Meraki hardware. * Circuit Validation: Utilize high-end diagnostic tools (VIAVI, NetAlly) to ensure Fiber and Ethernet circuits meet strict Service Level Agreements (SLAs). * NOC Collaboration: Act as the primary field liaison for our Network Operations Center, assisting in the turn-up of static IP blocks and complex routing tables. * MDF/IDF Management: Perform "deep-dive" audits of client server rooms to optimize equipment placement and extend demarcations. * Infrastructure Reliability: While the focus is logical, you will ensure the physical layer (Fiber/Copper) is spliced and terminated to enterprise standards., * First-Visit Resolution: Utilizing your Cisco expertise to solve routing loops or configuration mismatches that a standard tech would miss. * Network Integrity: Ensuring that every client handoff is clean, documented, and performing at 100% capacity. * Client Confidence: Serving as a trusted advisor to client IT managers, ensuring they feel secure in our network's reliability. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [IP Authentication: A Tale of Performance Pitfalls and Challenges in Prod](https://www.wearedevelopers.com/videos/1413-ip-authentication-a-tale-of-performance-pitfalls-and-challenges-in-prod) - [IoT: The road to sustainability](https://www.wearedevelopers.com/videos/557-iot-the-road-to-sustainability) - [Your Infrastructure Is Not a Playground: AI Agents for Infra Done Right](https://www.wearedevelopers.com/videos/2084-your-infrastructure-is-not-a-playground-ai-agents-for-infra-done-right) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Everything a Developer Needs to Know About MCP with Neo4j](https://www.wearedevelopers.com/magazine/604-everything-a-developer-needs-to-know-about-mcp-with-neo4j) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [How to Write a CV and Interview if You Don't Fully Qualify For The Job](https://www.wearedevelopers.com/magazine/183-how-to-write-a-cv-and-interview-if-you-don-t-fully-qualify-for-the-job)
