Role & Responsibilities:
We're seeking a Network Engineer with deep expertise in Cisco enterprise LAN and WLAN technologies to support a distributed campus and branch network environment. This role demands a balance of architectural thinking and hands-on execution - someone who can design with foresight, configure with precision, and troubleshoot under pressure.
You'll be responsible for maintaining and evolving a multi-site Cisco network built on high-availability, security, and scalability principles. The right engineer has seen networks break, learned from it, and knows how to build them better. * Design, implement, and support Cisco LAN/WLAN infrastructure across campus and branch offices - including Catalyst switching, ISR/ASR routing, and Catalyst/Aironet/Meraki wireless solutions.
* Perform RF design and wireless site surveys (Ekahau or similar), ensuring optimal WLAN coverage and performance.
* Maintain and optimize Cisco DNA Center, ISE, and WLCs for centralized management and visibility.
* Conduct capacity planning, performance tuning, and QoS optimization for real-time, and data services.
* Implement and maintain network segmentation, access control, endpoint profiling and security policies in coordination with cybersecurity teams.
* Implement security protocols and ensure compliance with industry standards (e.g., WPA3, 802.1X).
* Manage redundant WAN and SD-WAN links, ensuring optimal failover and traffic routing across sites.
* Lead network refresh, expansion, and migration projects, from design to deployment.
* Assist in capacity planning and future-proofing wireless infrastructure for scalability and emerging technologies (e.g., WiFi 6/6E/7, IoT).
* Troubleshoot complex issues across Layer 1-7, providing deep-dive analysis and long-term remediation.
* Develop and maintain accurate network documentation - diagrams, configurations, and operational procedures.
* Participate in on-call rotation and provide Tier 2/3 support for escalated network issues.
* Research, test, and recommend new LAN/WLAN technologies, network automation, and monitoring improvements. Qualifications: * 5 + years of experience supporting enterprise Cisco networks (campus and branch).
* Expert-level understanding of Cisco LAN technologies: VLANs, STP, EtherChannel, VTP, QoS, 802.1X, DHCP snooping, IP helper, etc.
* Strong knowledge of Cisco routing protocols: OSPF, EIGRP, and BGP; VRF and VXLAN experience a plus.
* Proficiency with WLAN standards (802.11a/b/g/n/ac/ax), wireless security (WPA2/3, 802.1X), and RF troubleshooting.
* Hands-on experience with Cisco DNA Center, ISE, and WLC platforms.
* Familiarity with Cisco Meraki cloud-managed networking is advantageous.
* Understanding of network automation and scripting (Python, Ansible, or REST APIs).
* Experience integrating with Cisco Secure Access (ISE/NAC) and implementing zero-trust principles.
* Skilled with network monitoring and visibility tools such as SolarWinds, NetFlow, or Cisco ThousandEyes.
* Excellent communication and documentation skills; able to translate technical insight into clear action. Preferred Qualifications: * CCNP Enterprise or higher (e.g., CCIE Enterprise Infrastructure a strong plus)
* CWNA / CWDP or equivalent WLAN certification
* Cisco Certified Specialist in Enterprise Design or Wireless Implementation
* Experience with Cisco DNA Center, and ISE.
* Exposure to cloud networking (Azure, AWS) and SD-WAN technologies.
* ITIL Foundation or similar process certification a plus
* Knowledge of network automation tools (Python, Ansible) is a plus. What Success Looks Like: * The network hums quietly - stable, secure, and optimized.
* Campus and branch users experience seamless connectivity, whether wired or wireless.
* You proactively identify issues before users notice them.
* Automation and visibility tools reduce manual intervention and increase uptime.
* You're a trusted voice in design discussions and a reliable partner during incident response.
