End -To- End Telco Engineer

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.
• Contribute to incident RCA inputs, end-to-end failure analysis, and service improvement recommendations.
• Maintain technical documentation related to service flows, dependencies, and known failure scenarios.
• Support Service Assurance governance processes, audits, and operational readiness reviews.
• Produce end-to-end incident analysis and troubleshooting inputs, service restoration validation and acceptance confirmation, RCA technical contributions and improvement recommendations, and documentation supporting service stability, audit readiness, and operational maturity.

Qualifications

Education:

Bachelor's degree in Telecommunications, Electronics & Communication Engineering, Electrical Engineering, or a related technical field.

Experience:

• 5-8 years of experience in telecom operations, service assurance, NOC engineering, or network troubleshooting roles.
• Proven experience troubleshooting cross-domain issues in mobile, satellite, or hybrid telecom environments.
• Strong understanding of end-to-end telecom architecture covering RAN, core, transport, OSS, and satellite systems.
• Hands-on experience analyzing KPIs, alarms, logs, and traces across multiple domains.
• Knowledge of signaling, session management, mobility, and service continuity concepts.
• Ability to reason across system boundaries rather than isolated components.

Preferred Qualifications:

• Advanced telecom or networking certifications.
• Experience supporting 4G/5G, NTN, satellite-integrated networks, or carrier-grade services.

Soft Skills:

• Strong analytical and problem-solving mindset with an end-to-end perspective.
• Excellent communication skills to translate complex technical findings into actionable guidance.
• Ability to operate calmly and decisively during high-severity incidents.
• Strong collaboration skills across Service Assurance, NOC, Managed Services, and engineering teams.

Technology Stack:

• OSS/NMS platforms and monitoring dashboards.
• ITSM and incident management tools (ServiceNow, Remedy, Jira Service Management, or equivalent).
• KPI visualization and analysis tools (Grafana, Power BI, or similar).
• Log analysis and diagnostic tools across RAN, core, and transport layers.

Physical Requirements

• Ability to lift up to 25 lbs.
• Ability to use a computer for extended periods.
• Ability to work in a fast-paced operational environment, including on-call or extended incident support when required.
• Ability to support global operations across time zones during major incidents or launch phases.
