This is not a basic helpdesk role. You will work directly with live network infrastructure — configuring routers, troubleshooting bonded links, supporting wireless backhaul, and maintaining high-availability systems across fiber, fixed wireless, and SD-WAN deployments. The ideal candidate has hands-on experience in ISP, WISP, FTTH, or managed service provider environments and is comfortable balancing customer communication with deep technical execution. What You’ll Own Customer Support & Troubleshooting - Respond promptly and professionally to customer calls and emails related to connectivity and performance. - Diagnose and resolve issues involving bonded WAN connections, wireless links, VoIP quality, and routing misconfigurations. - Troubleshoot CPE devices, routers, and firewalls in live production environments. - Document troubleshooting steps, root cause analysis, and configuration changes accurately. - Participate in a rotating after-hours emergency support schedule (1 week per month). - Consult with business clients on connectivity optimization and redundancy strategies when needed. Network Operations & Maintenance - Monitor and maintain core ISP infrastructure, including wireless backhaul, bonded WAN links, and edge routing devices. - Provision and configure new customer connections (router configuration, VLANs, firewall rules, QoS policies). - Troubleshoot BGP/OSPF routing issues and link failover events. - Configure and maintain MikroTik and Peplink devices in production. - Support tower deployments, backhaul upgrades, and infrastructure expansion projects. - Assist with firmware upgrades, configuration backups, and network hardening. - Maintain accurate network diagrams, IP addressing documentation, and system records. Team Collaboration - Work closely with internal engineering and field teams to resolve complex network issues. - Escalate critical infrastructure issues appropriately while maintaining ownership. - Contribute to improving uptime, redundancy, and network optimization. - Share documentation and operational insights to improve team knowledge. Must-Have Experience & Skills - Hands-on experience in an ISP, WISP, FTTH, or managed service provider environment. - Strong troubleshooting skills across routing, switching, and WAN connectivity. - Experience configuring routers and firewalls in production environments. - Solid understanding of TCP/IP, VLANs, NAT, VPNs, and QoS. - Experience working with BGP and/or OSPF. - Comfortable supporting both technical troubleshooting and customer communication. - Ability to work independently in a remote environment with strong documentation discipline. - Strong analytical and problem-solving mindset. Strongly Preferred (Highly Relevant Experience) - Experience with Peplink (SpeedFusion, InControl2) in multi-WAN or bonded link environments. - Hands-on experience with MikroTik RouterOS. - Experience with fixed wireless (PTP/PMP) deployments using Cambium or Ubiquiti. - Familiarity with mmWave backhaul systems (Siklu, Aviat, or similar). - Experience supporting Starlink or hybrid WAN deployments. - VoIP troubleshooting experience (SIP, QoS prioritization). Technical Environment You will be working across a modern ISP infrastructure that includes: - SD-WAN & Link Bonding: Peplink (SpeedFusion, InControl2) bonding Starlink, 5G, and terrestrial links. - Fixed Wireless (PMP/PTP): Cambium and Ubiquiti networks. - High-Capacity Backhaul: Siklu (mmWave) and Aviat technologies. - Enterprise Wi-Fi: Cambium (cnMaestro) and Ubiquiti (UniFi). - Routing & Protocols: MikroTik (RouterOS), BGP, OSPF, VLAN segmentation. - VoIP: SIP troubleshooting and QoS optimization. Key Metrics for Success - Fast, accurate resolution of support tickets. - High network uptime and minimal service disruption. - Successful provisioning and configuration of new customer connections. - Accurate and complete documentation of network changes. - Reduced repeat escalations and strong customer satisfaction. Interview Process - Initial Screening Call - Technical Interview - Practical Troubleshooting Scenario - Final Interview - Offer & Onboarding #Meta
