About the Role
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.
