This role is responsible for the day-to-day reliability and performance of campus and branch connectivity, partners with security and infrastructure teams to integrate identity and access controls (e.g., Cisco ISE), and drives continuous improvement through standardization, documentation, and automation. The Principal IT Engineer leads incident triage and resolution, executes change activities using established change-management practices (e.g., ServiceNow), mentors junior engineers, and contributes to technical direction and roadmap planning. This position is hybrid and requires regular onsite presence in Somerset, NJ or Austin, TX, with scheduling determined by business needs., * Design, configure, and operate Cisco Wireless LAN Controllers (e.g., Catalyst 9800 series) and Meraki wireless networks. * Plan and optimize RF designs (channel, power, roaming, capacity) and validate changes using surveys and spectrum analysis. * Implement and maintain SSIDs, guest access, segmentation, and wireless security standards aligned to corporate policies. * Troubleshoot complex wireless issues across controller, access point, client, and authentication layers; lead root-cause analysis and remediation. * Integrate wireless access with Cisco ISE (802.1X, MAB, posture/policy) to enforce identity-based access controls. * Monitor wireless health and user experience; define and improve alerts, KPIs, and operational runbooks. Routing & Switching (LAN/WAN) * Design, implement, and maintain enterprise LAN/WAN infrastructure, including campus and branch connectivity. * Configure, optimize, and troubleshoot routing and switching technologies (e.g., VLANs, STP, HSRP/VRRP, OSPF, BGP; EIGRP where applicable). * Operate Cisco switching and routing platforms (e.g., Catalyst, Nexus) and associated services (DHCP relay, DNS dependencies, NTP, QoS). * Engineer resiliency and high availability, including redundant paths, fast convergence, and failover testing, and document design decisions. * Monitor and analyze performance using telemetry and network-management methods (e.g., SNMP, NetFlow) to drive performance improvements. * Plan and execute upgrades, expansions, and lifecycle refreshes in partnership with site IT, security, and application stakeholders. Operations, Monitoring & Continuous Improvement * Lead incident triage, escalation, and resolution for network-related events; perform root-cause analysis and implement preventative actions. * Maintain operational hygiene, including monitoring and alert tuning, capacity tracking, asset and configuration accuracy, and routine health checks. * Execute changes through established change-management processes (e.g., ServiceNow), including risk assessment, implementation planning, and backout procedures. * Create and maintain network documentation (standards, diagrams, runbooks) and promote reuse and standardization across sites. * Automate repeatable tasks and reporting using scripts and APIs; identify opportunities to reduce manual effort and improve reliability. * Partner with service desk teams and junior engineers to enhance troubleshooting workflows and knowledge-sharing resources. Behaviors and Competencies * Communication: Can effectively communicate complex ideas and information to diverse audiences and can facilitate effective communication between others. * Adaptability: Can proactively adapt to challenging situations, anticipate changes, and make modifications to meet the demands of changing circumstances. * Self-Motivation: Can proactively seek out challenges, initiate self-development projects, and contribute to personal or professional innovative ideas. * Teamwork: Can lead a team effectively, facilitating cooperation, sharing information, and ensuring that all team members are able to contribute to their full potential. * Analytical Thinking: Can synthesize complex data, identify patterns, draw insights, and present findings clearly and understandably. * Detail-Oriented: Can manage complex tasks or projects, identifying errors or inconsistencies, and ensuring all details are addressed, necessary corrections are made, and quality is maintained. * Organization: Can effectively coordinate multiple projects, delegate tasks where appropriate, and employ advanced organizational tools and methods. * Problem-Solving: Can proactively identify potential problems, initiate preventive measures, and propose and contribute to innovative solutions. * Initiative: Can proactively seek out challenges, initiate projects, and contribute to innovative ideas. * Technical Troubleshooting: Can proactively seek out potential technical problems, initiate preventive measures, and contribute to innovative solutions. ## 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) - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [Small, Secure, Interconnected: The next Internet Protocol](https://www.wearedevelopers.com/videos/100062-small-secure-interconnected-the-next-internet-protocol) - [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) - [A Technical Introduction to Bitcoin's 2nd Layer- The Lightning Network](https://www.wearedevelopers.com/videos/15-a-technical-introduction-to-bitcoin-s-2nd-layer-the-lightning-network) - [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) - [Best Paying Jobs in Technology](https://www.wearedevelopers.com/magazine/256-best-paying-jobs-in-technology) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers)
