Descripción del empleo

AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight.

Position Overview

We are seeking a RAN Wireless NOC Engineer to monitor, triage, and ensure the stability of 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. By diagnosing faults, validating service paths, and responding to alarms across commercial and beta services, this role ensures compliant service flows and minimizes customer-impacting disruptions, playing a critical role in 24/7 operational continuity and rapid incident response.

Key Responsibilities

• Monitor signaling pathways, routing behavior, SIM flows, OSS hooks, and cross-core interactions impacting satellite service.
• Detect, acknowledge, and triage alarms from monitoring platforms, ensuring rapid response and detailed logging.
• Escalate anomalies based on severity, impact, and operational thresholds.
• Validate routing tables, signaling transactions, and core-network behavior during faults or degradation events.
• Diagnose issues across gateway, core, OSS, and cross-domain integrations affecting service connectivity.

• Maintain accurate logs, incident records, and ticket updates for internal and external teams.
• Provide shift-handover summaries, incident reports, and RCA inputs when needed.
• Track recurring issues and propose remediation actions to service assurance leadership.
• Produce real-time monitoring logs, incident tickets, and alarm responses; routing validation reports, signaling analysis outputs, and incident triage documentation; shift handover summaries and partner-coordination records; RCA inputs and recurring-issue tracking reports; updated SOPs, playbooks, troubleshooting guides, and operational runbooks; and service quality dashboards and periodic operational health summaries.
