RAN NOC Engineer — 24/7 Satellite Connectivity

AST & Science, LLC; Lanham (MD); Vor Ort; USD 100.000 - 150.000; Vollzeit

Zusammenfassung

AST SpaceMobile seeks a RAN Wireless NOC Engineer to monitor and triage satellite connectivity across signaling, routing, SIM provisioning, and OSS integrations. You will coordinate with partner NOCs, diagnose faults, and ensure high availability for commercial and beta services in a 24/7 operations environment.

The role requires 2–5 years in NOC operations, strong knowledge of Diameter, SIP, NAS, and core-network behavior, plus experience with Linux and scripting.

Qualifikationen

• Bachelor's degree in Telecommunications, Computer Science, Electronics, or a related technical field.
• 2–5 years in NOC operations, telecom monitoring, satellite operations, or core-network support.
• Experience with signaling flows, routing, authentication paths, and mobile-core elements.
• Hands-on exposure to multi-vendor NOC operations and incident workflows.
• Strong understanding of signaling (Diameter, SIP, NAS), routing fundamentals, and core-network behavior.
• Knowledge of SIM activation, attach procedures, mobility, and authentication.
• Experience analyzing logs, traces, and event correlations across network elements.
• Familiarity with OSS/NMS tools, alarms, KPIs, dashboards, and monitoring platforms.
• Hands-on experience with Linux and basic scripting (Python/Bash).

Aufgaben

• 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.
