RAN Wireless NOC Engineer

AST SpaceMobile•Lanham, MD

About The Position

AST SpaceMobile is building SpaceMobile, a space-based cellular broadband network intended to provide 4G/5G connectivity to standard smartphones around the world. The RAN Wireless NOC Engineer monitors, triages, and helps maintain satellite connectivity across signaling, routing, SIM provisioning, OSS integrations, and core-network interactions. The role responds to alarms, validates routing behavior, diagnoses signaling and gateway/core issues, and coordinates with partner NOCs to sustain high availability for commercial and beta-grade connectivity. It contributes to 24/7 operational continuity and rapid incident response by diagnosing faults, validating service paths, and minimizing customer-impacting disruptions. The engineer works in a shift-based NOC environment and supports operational readiness for new services, partner integrations, and routing changes. The position produces monitoring logs, incident tickets, routing and signaling analyses, handover summaries, partner-coordination records, RCA inputs, operational documentation, and service-quality reporting. Duties and scope may change according to business demands.

Requirements

Bachelor's degree in Telecommunications, Computer Science, Electronics, or a related technical field.
2–5 years of experience 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 such as Diameter, SIP, and NAS, as well as routing fundamentals and core-network behavior.
Knowledge of telecom connectivity flows, including SIM activation, attach procedures, mobility, and 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 Python or Bash scripting, and troubleshooting tools.
Strong analytical skills and ability to diagnose issues under time pressure.
Excellent communication skills 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 approach and strong ownership of incident resolution and service quality.
Ability to lift up to 25 lbs.
Ability to use a computer for extended periods and remain attentive during extended monitoring sessions and incident bridges.
Ability to work in a shift-based NOC environment, including nights or weekends based on rotation.

Nice To Haves

Networking certifications such as CCNA, CCNP, JNCIA, or JNCIS, or certifications in telecom operations.
Basic understanding of satellite network components, gateways, or hybrid RAN-core flows.
Familiarity with NOC and OSS/NMS tools such as Zabbix, Grafana, Prometheus, Datadog, or SolarWinds.
Familiarity with logging tools such as Elastic, Splunk, or Kibana and packet-analysis tools such as Wireshark.
Familiarity with ticketing/ITSM tools such as ServiceNow, Jira, or Remedy.
Basic scripting and automation familiarity with Python or Bash.
Strong working knowledge of Excel, dashboards, and documentation tools.
Ability to travel occasionally for training, partner coordination, or operational readiness activities.

Responsibilities

Monitor signaling pathways, routing behavior, SIM flows, OSS hooks, and cross-core interactions affecting satellite service.
Detect, acknowledge, and triage alarms from monitoring platforms, with rapid response and detailed logging.
Escalate anomalies according to severity, impact, and operational thresholds.
Validate routing tables, signaling transactions, and core-network behavior during faults or service degradation.
Diagnose connectivity issues across gateway, core, OSS, and cross-domain integrations.
Analyze events, correlate logs, and support root-cause investigations with engineering teams.
Act as the operational interface with partner NOCs for incident handling, alarm correlation, and workflow alignment.
Coordinate multi-party triage calls, share logs and findings, and track partner-linked issues through closure.
Maintain communication loops and follow defined escalation paths.
Ensure signaling and routing flows comply with requirements across commercial and beta-grade service classes.
Conduct periodic checks of SIM provisioning paths, authentication flows, and connectivity stability.
Validate OSS integration points, alarms, KPIs, and data hooks used for service-assurance visibility.
Contribute to playbooks, SOPs, troubleshooting guides, and operational runbooks for core, gateway, and OSS interactions.
Support readiness for new services, partner integrations, and routing changes through pre-launch validation tests.
Provide feedback on monitoring thresholds, dashboards, and workflows to improve detection and response.
Maintain accurate logs, incident records, and ticket updates for internal and external teams.
Prepare shift-handover summaries, incident reports, and RCA inputs as needed.
Track recurring issues and propose remediation actions to service-assurance leadership.
Produce real-time monitoring logs, incident tickets, alarm responses, routing validation reports, signaling analysis outputs, triage documentation, partner-coordination records, recurring-issue reports, updated operational documentation, and service-quality dashboards and health summaries.
