Senior Network Engineer - Wi-Fi & Wireless Systems

Senior Network Engineer - Wi-Fi & Wireless Systems Location: Remote Department: Enterprise Network Infrastructure / Wireless Engineering Employment Type: Full-Time About the Role: We are looking for an experienced and forward-thinking Senior Network Engineer with deep domain expertise in enterprise-grade Wi-Fi and wireless communication technologies. In this role, you will be responsible for designing, deploying, securing, troubleshooting, and optimizing our global wireless infrastructure. You will work closely with security, systems, and global IT teams to ensure high-performance, ultra-reliable, and secure Wi-Fi connectivity across our offices, campuses, and remote facilities. Key Responsibilities: - Wireless Architecture & Design: Lead the end-to-end design, architecture, and deployment of enterprise-grade WLAN solutions, utilizing advanced predictive and on-site RF site surveys (using tools like Ekahau). - Implementation & Configuration: Configure and manage enterprise wireless controllers, access points (APs), and cloud management platforms (e.g., Cisco Meraki, Aruba Central, Juniper Mist). - Optimization & Performance Tuning: Continuously monitor and tune RF environments (channel allocation, power levels, channel width, and band steering) to mitigate interference, reduce latency, and maximize client throughput. - Security & Access Control: Implement robust wireless security frameworks (802.1X, WPA3-Enterprise, RADIUS/TACACS+, rogue AP detection, and secure guest access segmentation). - Troubleshooting & Incident Response: Serve as the final escalation point (Tier 3/4) for complex wireless connectivity, roaming issues, authentication failures, and performance bottlenecks. - Automation & Monitoring: Leverage automation scripts (Python, Ansible) and network telemetry to streamline configuration management, track network KPIs, and automate routine operational tasks. Required Qualifications & Skills: Professional Experience & Wireless Expertise: - 5+ years of hands-on experience in enterprise network engineering with a heavy specialization in wireless/Wi-Fi design and operations. - Deep technical knowledge of IEEE 802.11 standards (Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7), roaming protocols (802.11r/k/v), and RF characteristics (RSSI, SNR, multipath interference). - Extensive experience working with enterprise WLAN hardware and platforms (e.g., Cisco Catalyst/Meraki, ArubaOS/Central, Juniper Mist). Networking Core Competencies: - Solid understanding of routing and switching fundamentals (TCP/IP, VLANs, OSPF/BGP, STP, trunking, and PoE management). - Familiarity with DHCP, DNS, and AAA/RADIUS architectures (ClearPass, Cisco ISE). - Experience with packet analysis tools (e.g., Wireshark) for deep-dive wireless frame analysis. Certifications: - CWNP Certified Wireless Network Professional certification (e.g., CWDP, CWSP, or CWNE) strongly preferred. - Industry vendor certifications such as CCNP Enterprise / CCNA Wireless or Aruba Certified Mobility Professional (ACMP). Preferred Qualifications: - Experience managing wireless infrastructure in high-density environments (e.g., large open-office setups, auditoriums, warehouses). - Familiarity with location-based services (LBS), Wi-Fi asset tracking, and IoT wireless integration (Zigbee, BLE). - Coding or scripting proficiency in Python or Bash for network automation.
