RAN Wireless NOC Engineer at AST SpaceMobile in Lanham, MD

Job description

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. Perform detailed event analysis, correlate logs, and support root-cause investigations with engineering teams. Serve as the operational interface with partner NOCs across incident handling, alarm correlation, and workflow alignment. Coordinate multi-party triage calls, share logs and findings, and ensure timely tracking and closure of partner-linked issues. Maintain consistent communication loops and follow defined escalation paths. Ensure signaling and routing flows remain compliant across commercial and beta-grade service classes. Perform periodic checks on SIM provisioning paths, authentication flows, and connectivity stability. Validate OSS integration points, alarms, KPIs, and data hooks supporting service assurance visibility. Contribute to playbooks, SOPs, and troubleshooting guides for core/gateway/OSS interactions. Support readiness for new services, partner integrations, and routing changes by conducting pre-launch validation tests. Provide feedback on monitoring thresholds, dashboards, and workflow improvements to enhance detection and response. 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. Qualifications Education: Bachelor's degree in Telecommunications, Computer Science, Electronics, or a related technical field. Experience: 2-5 years in NOC operations, telecom monitoring, satellite operations, or core-network support. Experience working with signaling flows, routing tables, authentication paths, or mobile-core elements. Hands-on exposure to multi-vendor NOC operations, incident workflows, and partner escalations. Strong understanding of signaling (e.g., Diameter, SIP, NAS), routing fundamentals, and core-network behavior. Knowledge of telecom connectivity flows (SIM activation, attach procedures, mobility, authenticati
