L1FM Engineer- Transmission

Join our Team

About This Opportunity

We are looking for a skilled and proactive L1 Fault Management Engineer – Transmission to join our Network Operations team at Ericsson, Noida. In this role, you will be an integral part of our 24x7 global operations environment, responsible for real-time alarm monitoring, first-level fault analysis, and incident management across Transmission network domains including SDH, PDH, DWDM, IPMPLS, and Microwave technologies.

This is an excellent opportunity for telecom professionals looking to deepen their expertise in transmission networks while contributing to Ericsson's vision of a fully connected, intelligent world.

What You Will Do

Alarm Monitoring & Fault Management

• Perform 24x7 alarm monitoring and first-level fault management (L1FM) across Transmission network elements
• Identify, classify, and prioritize alarms — critical, major, and minor — impacting transmission services
• Perform alarm correlation and event filtering to isolate root causes before L2/L3 escalation
• Detect service-impacting transmission faults and initiate timely incident response
  
  

Transmission Domain Coverage

Monitor and manage alarms across the following transmission technologies:

SDH- LOS, LOF, AIS, RDI alarms; MSP/SNCP protection switching events; fiber & transmission faults

PDH- E1/T1 degradation, synchronization and framing issues

DWDM- Optical power alarms, wavelength failures, amplifier/transponder faults, fiber cut identification

MW- Link degradation, RSL alarms, rain fade events, equipment faults

IP/MPLS- Link down alarms, LSP failures, interface utilization alerts

Incident Management

• Create and manage incident tickets accurately in ITSM/ticketing tools (BMC Remedy, JIRA)
• Capture detailed fault descriptions, impact assessments, and troubleshooting notes
• Assign and escalate tickets to L2/L3 transmission teams within defined SLAs
• Track incidents end-to-end and ensure timely resolution and closure
  
  

Escalation & Communication

• Escalate critical transmission faults to L2/L3 teams per the defined escalation matrix
• Provide regular and accurate updates to stakeholders during major outages
• Participate in shift handovers with clear documentation of open and ongoing issues
• Prepare and distribute incident notifications, outage reports, and RFO (Reason for Outage) summaries
  
  

What You Will Bring

Technical Skills

Transmission Technologies:

• SDH, PDH, DWDM, Microwave, IP/MPLS (Transport Layer)
  
  

Network Management Tools:

• NMS/EMS platforms (Ericsson OSS, TNMS, or equivalent)
• Netcool, Spectrum, SolarWinds (preferred)
• Multi-vendor EMS tools for transmission network monitoring
  
  

ITSM Tools:

• BMC Remedy, JIRA, or similar ticketing systems
  
  

Protocol & Concept Knowledge:

• Transmission fundamentals — SDH/PDH hierarchy, optical networking basics
• SNMP, TCP/IP fundamentals
• ITIL-based incident management process awareness
