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 OverviewWe 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.
QualificationsEducation: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, authentication).
- Experience analyzing logs, traces, routing tables, and event correlations across network elements.
- Familiarity with OSS/NMS tools, alarms, KPIs, dashboards, and monitoring platforms.
- Hands-on experience with Linux, basic scripting (Python/Bash), and troubleshooting tools.
Preferred Qualifications: - Certifications in networking (CCNA, CCNP, JNCIA, JNCIS) or telecom operations.
- Basic understanding of satellite network components, gateways, or hybrid RAN-core flows.
Soft Skills:- Strong analytical skills and ability to diagnose issues under time pressure.
- Excellent communication for coordination with internal teams and partner NOCs.
- High attention to detail with disciplined documentation and tracking.
- Adaptability to shift-based schedules and fast-paced incident environments.
- Team-oriented mindset with strong ownership of incident resolution and service quality.
Technology Stack:- NOC and OSS/NMS tools (Zabbix, Grafana, Prometheus, Datadog, SolarWinds, or similar).
- Logging tools (Elastic, Splunk, Kibana) and packet analysis tools (Wireshark).
- Ticketing/ITSM tools (ServiceNow, Jira, Remedy).
- Basic scripting and automation familiarity (Python, Bash).
- Strong working knowledge of Excel, dashboards, and documentation tools.
Physical Requirements- Ability to lift up to 25 lbs.
- Ability to use a computer for extended periods.
- Ability to work in a shift-based NOC environment, including nights or weekends based on rotation.
- Ability to remain attentive during extended monitoring sessions and incident bridges.
- Occasional travel for training, partner coordination, or operational readiness activities.
