End-to-End Telco Engineer

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

We are seeking a End -To- End Telco Engineer to ensure end-to-end service stability and performance across satellite-to-mobile services by diagnosing and resolving cross-domain issues spanning satellite, RAN, core, transport, and OSS layers. Operating within the Service Assurance organization, this role serves as the technical authority for multi-domain incident analysis, working closely with PSC Agents, NOC Telco Engineers, and Managed Services teams to restore service, validate service flows, and ensure compliant end-to-end connectivity during launch, early-life support, and steady-state operations. This role is critical to maintaining end-to-end service integrity for satellite-to-mobile communications, ensuring that incidents are not only resolved but fully understood across domains, enabling reliable service delivery, customer confidence, and scalable global operations. 

Key Responsibilities:

• Analyze service degradation or outages across multiple network domains, including satellite payload, RAN, gateway, core network, transport, and OSS.
• Assess customer and service impact from an end-to-end perspective, identifying cross-domain dependencies and failure points.
• Correlate alarms, KPIs, logs, and incident timelines to determine end-to-end service behavior.
• Lead technical troubleshooting for complex incidents requiring multi-domain coordination.
• Identify root causes spanning more than one network domain and guide corrective actions.
• Validate fixes and mitigations to ensure full end-to-end service restoration, not partial recovery.
• Work closely with AST NOC Telco Engineers and Nokia Managed Services NOC Engineers to guide triage, troubleshooting depth, and escalation decisions.
• Provide technical direction to PSC Agents for accurate customer updates and incident status.
• Participate in major incident bridges, restoration reviews, and technical war rooms as required.
• Validate end-to-end service flows, including attach, session establishment, mobility, throughput, and persistence.
• Ensure service performance meets defined SLA, KPI, and regulatory requirements.
• Support acceptance of restored services before formal incident closure.
