At Pavago , we’re hiring an ISP Network Support Engineer for one of our clients to support customer-facing troubleshooting and production network operations across a growing multi-WAN ISP environment.

This is not a basic helpdesk role . You’ll work directly with live network infrastructure across fiber, fixed wireless, bonded WAN, Starlink, and SD-WAN deployments , troubleshooting complex connectivity issues and maintaining reliable, high-availability services.

You’ll work hands-on with technologies including MikroTik RouterOS, Peplink SpeedFusion, BGP, OSPF, Cambium, Ubiquiti, Siklu, Aviat, and enterprise wireless infrastructure .

This role is particularly well suited to someone with hands-on ISP, WISP, FTTH, or MSP experience who is comfortable troubleshooting production networks while communicating directly with customers.

Diagnose customer issues involving

• Connectivity and outages
• Latency and packet loss
• Routing instability
• VoIP and call-quality problems
• WAN and failover performance

Troubleshoot bonded WAN, SD-WAN, VPN, VLAN, and wireless connectivity issues .
