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. Position Overview The NOC Engineer (Service Assurance) is responsible for monitoring, triaging, and ensuring 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. Reporting to the Service Assurance Manager, the NOC Engineer plays a critical role in 24/7 operational continuity and rapid incident response.
Responsibilities:
•
Network Monitoring & Event Handling
•
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.
•
Incident Diagnosis & Troubleshooting
•
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.
•
Partner NOC Coordination
•
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.
Requirements:
•
Bachelor’s degree in Telecommunications, Computer Science, Electronics, or related technical field.
•
Certifications in networking (CCNA, CCNP, JNCIA, JNCIS) or telecom operations are advantageous.
•
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.
•
Required Technical Expertise
•
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, authentication).
•
Experience analyzing logs, traces, routing tables, and event correlations across network elements.
•
Familiarity with OSS/NMS tools, alarms, KPIs, dashboards, and monitoring platforms.
•
Basic understanding of satellite network components, gateways, or hybrid RAN‑core flows is a plus.
•
Hands‑on with Linux, basic scripting (Python/Bash), and troubleshooting tools.
