AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.

We are seeking a NOC Infrastructure Engineer (Service Assurance) to monitor, triage, and ensure the stability of the physical network and compute layer of our telco environments. This role ensures the reliability, performance, and scalability of networks, firewalls, server hardware, racks, power, cabling, and related physical systems that support global production, lab, and test workloads, as well as satellite connectivity across signaling, routing, SIM provisioning, OSS integrations, and core-network interactions.

This role handles alarms, validates routing behavior, diagnoses signaling and gateway/core issues, and coordinates closely with partner NOCs to maintain high availability across commercial and beta-grade connectivity flows. The ideal candidate brings deep hands-on experience with datacenter operations, Cisco networking, physical computer hardware, and infrastructure best practices.
