5G Rf Optimization Engineer Jobs in Iselin, NJ (NOW HIRING)

An established and growing managed services provider in NYC is seeking a skilled and client-focused Wireless Network Engineer to join its network engineering team. In this role, you will serve as the subject matter expert (SME) for enterprise wireless network design, deployment, and optimization across a diverse client base spanning multiple industries.

• Strong written and verbal communication skills with a track record of making technical content accessible to non-technical audiences

Technical Skills

• Deep expertise across 802.11 standards (a/b/g/n/ac/ax/be) and enterprise wireless architecture
• Solid command of core networking fundamentals including IP addressing, DHCP, DNS, and VLAN design
• Strong grasp of RF principles, SSID architecture, wireless controller management, and high-density Wi-Fi design
• Hands-on experience implementing wireless security including 802.1X/RADIUS authentication, WPA2/WPA3-Enterprise encryption, and guest network segmentation
• Proficiency with wireless packet capture and analysis tools such as Wireshark or AirPCAP
• Comfort supporting Apple ecosystems (macOS, iOS) and common business productivity platforms including Google Workspace
• Ability to produce polished technical documentation including network diagrams, AP placement maps, rack elevations, and client-facing assessment reports
