Job Description

The L3 RAN Level Assurance Engineer is responsible for 2nd-level assurance and fault management across RAN technologies (2G/3G/4G/5G). The role focuses on triaging and resolving jeopardy alerts and customer-impacting faults within defined SLAs/WLAs, coordinating with field operations, L2/L3 teams, vendors and customers, and maintaining high operational standards in a 24x7 environment.

What you will do:

Monitor, triage and resolve jeopardy alerts and fault tickets within SLA/WLA targets.
Perform initial ticket triage: analyse fault tickets, determine root cause where possible, and route accurately to L2/L3 or external vendors with clear instructions.
Maintain clear, concise and complete ticket notes (actions taken, access requests, approvals, timestamps, references) to make handovers executable.
Act as first point of contact for fault-related issues and escalate to management when required.
Drive incident and problem management activities: own critical trouble tickets, coordinate RCA and corrective actions.
Coordinate vendor (3PP) engagement and manage vendor SLAs and support contracts as needed.
Provide Level 1/2 support for customer complaints and ensure timely updates and closure.
Monitor system alarms and execute escalation matrices for BSC / RNC / RBS / hardware / transmission faults.
Perform preventive maintenance activities such as daily health-checks, fallback reports and take corrective actions.
Use and manage OSS/ENM/Ticketing tools and authorized 3PP tools per project requirement.
Prioritise faults to meet business KPIs and deliver operational excellence to internal/external customers.

The skills you bring:

Solid knowledge of RNC/BSC/RBS/NR nodes and fronthaul/transport equipment (SIU, routers, DWDM, HPA, DAS, train repeaters).
Deep familiarity with RAN KPI s (2G/3G/4G/5G), call flows, channel concepts, handover behaviour and cell-site issues.
Hands-on experience with Ericsson, Huawei and/or Nokia RAN equipment and ENM/OSS tools.
Basic to intermediate Linux/Unix knowledge for log analysis and troubleshooting.
Understanding of Core/IP architecture and ability to correlate core issues affecting access network.
Real-time critical trouble ticket handling experience for customer complaint resolution.
Experience performing health-checks, fallback analysis and preventive maintenance on RNC/BSC.

Qualification And Experience:

Degree in Electrical Engineering or Telecommunication Engineering.
1 5 years of relevant telecom experience in RAN operations, fault management or field support.
Valid passport and willingness to travel on-site as per terms.
Strong ability to interpret technical fault tickets and route accurately within KPIs.
Demonstrated experience handling fault tickets end-to-end and coordinating fixes.
Strong organisational skills and ability to multi-task in a high-pressure, 24x7 environment.
Excellent written and verbal communication; able to prepare concise reports and adapt communication to the audience.
Good knowledge of Microsoft Office (Word, Excel, PowerPoint, Visio, Project)
