End to End Telco Engineer

Position Overview

The E2E Telco Engineer in Service Assurance team is responsible for ensuring endtoend service stability and performance across satellitetomobile services by diagnosing and resolving crossdomain issues spanning satellite, RAN, core, transport, and OSS layers.

Operating within the Service Assurance organization, this role serves as the technical authority for multidomain incident analysis, working closely with PSC Agents, NOC Telco Engineers, and Managed Services teams to restore service, validate service flows, and ensure compliant endtoend connectivity during launch, earlylife support, and steadystate operations.

This role is critical to maintaining endtoend service integrity for satellitetomobile communications. The E2E Telco Engineer ensures that incidents are not only resolved but fully understood across domains, enabling reliable service delivery, customer confidence, and scalable global operations.

Key Responsibilities

EndtoEnd Service Analysis & Impact Assessment

• 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 endtoend perspective, identifying crossdomain dependencies and failure points.

• Correlate alarms, KPIs, logs, and incident timelines to determine endtoend service behavior.

CrossDomain Troubleshooting & Resolution

• Lead technical troubleshooting for complex incidents requiring multidomain coordination.

• Identify root causes spanning more than one network domain and guide corrective actions.

• Validate fixes and mitigations to ensure full endtoend service restoration, not partial recovery.

NOC & Service Assurance Coordination

• 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.

Service Flow Validation & Performance Assurance

• Validate endtoend 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.

Governance, Documentation & Continuous Improvement

• Contribute to incident RCA inputs, endtoend 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.

Deliverables

• Endtoend incident analysis and troubleshooting inputs.

• Service restoration validation and acceptance confirmation.

• RCA technical contributions and improvement recommendations.

• 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.

• Advanced telecom or networking certifications are a plus.

Experience

• 5-8 years of experience in telecom operations, service assurance, NOC engineering, or network troubleshooting roles.

• Proven experience troubleshooting crossdomain issues in mobile, satellite, or hybrid telecom environments.

• Experience supporting 4G/5G, NTN, satelliteintegrated networks, or carriergrade services is strongly preferred.

Required Technical Expertise

• Strong understanding of endtoend telecom architecture covering RAN, core, transport, OSS, and satellite systems.

• Handson 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.

Professional Skills

• Strong analytical and problemsolving mindset with an endtoend perspective.

• Excellent communication skills to translate complex technical findings into actionable guidance.

• Ability to operate calmly and decisively during highseverity incidents.

• Strong collaboration skills across Service Assurance, NOC, Managed Services, and engineering teams.

Technology Proficiency

• 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 work in a fastpaced operational environment, including oncall or extended incident support when required.

• Ability to support global operations across time zones during major incidents or launch phases.

• Role is being recruited in India to support regional customer engagement, timezone aligned operations, and 247 Service Assurance coverage
