Starlink * 5G \& terrestrial bonding **Fixed Wireless Networks*** Cambium * Ubiquiti * PTP/PMP deployments **Backhaul Infrastructure*** Siklu (mmWave) * Aviat * High\-capacity wireless transport **Enterprise Wi\-Fi*** Cambium cnMaestro * UniFi **Routing \& Networking*** MikroTik RouterOS * BGP * OSPF * VLAN segmentation * NAT * QoS * VPNs **VoIP \& QoS*** SIP troubleshooting * QoS prioritization * VoIP optimization **What We’re Looking For****Required Experience \& Skills*** Hands\-on experience in: * + ISP + WISP + FTTH + MSP environments * Strong troubleshooting skills involving: * + routing + switching + WAN connectivity + failover systems * Experience configuring: * + routers + firewalls + VLANs + VPNs * Strong understanding of: * + TCP/IP + NAT + QoS + VLANs + BGP + OSPF * Strong documentation and communication skills * Comfortable balancing: * + technical troubleshooting + customer communication * Ability to work independently in remote environments * **Strongly Preferred** * Peplink / SpeedFusion experience * MikroTik RouterOS expertise * Experience with: * + Cambium + Ubiquiti + Siklu + Aviat * Experience with: * + fixed wireless deployments + mmWave backhaul systems * Familiarity with: * + Starlink + hybrid WAN deployments * VoIP troubleshooting experience: * + SIP + QoS + voice optimization **What Makes You a Great Fit*** You enjoy solving complex network problems * You stay calm during outages and troubleshooting scenarios * You care about uptime, redundancy, and reliability * You think proactively about optimization and scalability * You can communicate technical issues clearly to customers and internal teams * You take ownership instead of escalating everything immediately **What a Typical Day Looks Like*** Troubleshoot customer connectivity and routing issues * Configure routers, VLANs, firewalls, and QoS policies * Monitor network infrastructure and wireless backhaul systems * Investigate failover or BGP/OSPF routing events * Provision new customer deployments * Support VoIP quality optimization * Update documentation and network diagrams * Collaborate with engineering and field teams on escalations and deployments **In short:** You help keep ISP infrastructure stable, scalable, and highly available while solving real\-world networking issues across live production systems. **Key Success Metrics (KPIs)*** Fast and accurate ticket resolution * High network uptime and reliability * Reduced repeat escalations * Successful provisioning of new customer connections * Accurate documentation and configuration management * Strong customer satisfaction and communication quality **Why This Role Stands Out*** Direct exposure to real ISP/WISP infrastructure * Work across: * + SD\-WAN + wireless backhaul + BGP routing + multi\-WAN failover + VoIP optimization * High ownership and technical depth * Opportunity to work with modern networking technologies * Exposure to large\-scale wireless and hybrid WAN environments * Strong career growth into: * + Network Engineering + Infrastructure Engineering + Senior ISP Operations + Network Architecture **Interview Process*** Initial Screening Call * Technical Interview * Practical Troubleshooting Scenario * Final Interview * Offer \& Onboarding **Apply Now** If you: * Thrive in live networking environments * Enjoy troubleshooting complex ISP infrastructure * Have hands\-on routing and wireless experience * Want ownership over real production systems This role is a strong fit for you.
