Main activities and tasks:

• Provide back-office support for RAN network elements, ensuring optimal performance, stability, and availability of the mobile network.
• Manage the full lifecycle of RAN-related Incidents, Problems, and Changes, including troubleshooting, escalation, and closure of Trouble Tickets (TTs) and Service Requests (SRs) within agreed SLAs.
• Perform preventive maintenance and performance management, proactively monitoring KPIs, alarms, and traffic trends to detect and resolve degradations.
• Conduct root cause analysis (RCA) of major Incidents, propose corrective actions, and support Problem Management with permanent solutions.
• Participate in implementation and configuration activities: create Work Orders (WOs), validate parameters, configure network elements, and support new node integrations in coordination with field teams.
• Support Change Management by planning, preparing, and executing configuration changes, software upgrades, parameter updates, and feature activations in the live RAN environment, in line with approved MoPs.
• Provide remote support to field engineers during implementation, migration, or troubleshooting activities, ensuring compliance with safety and access procedures.
• Participate in acceptance testing of new RAN sites, software releases, or parameter changes, validating network performance and updating operational databases (e.g., Ramsite, OSS).
• Deliver reports and documentation on incidents, changes, performance trends, and preventive actions, ensuring proper knowledge base contribution.
• Support continuous improvement initiatives, including RAN optimization activities (parameter tuning, mobility management, energy optimization, interference handling, public event assurance).
• Cover 24x7 on-call duties, providing out-of-hours technical authority support for urgent incidents or escalations.
• Train, mentor, and support junior engineers when designated by the line manager.
• Ensure compliance with project requirements and ITIL-aligned processes for Incident, Problem, Change, Event, and Release Management.
• Liaise with operators, vendors, and third parties to ensure seamless fault resolution, change execution, and service restoration.

Required Education & Trainings:

• Bachelor’s degree in Telecommunications, Electronics, or IT Engineering (or equivalent experience).
• Vendor or technology-specific certifications (Ericsson preferred, Nokia, Huawei RAN, 5G) are an advantage.
• Required Experience:
• Solid knowledge of Mobile Networks RAN technologies, architecture, and protocol stacks.
• Proven experience in Back Office / 2nd line RAN operations, including Incident and Change Management.
• Hands-on experience with RAN configuration, parameter tuning, and fault handling.
• Knowledge of network monitoring tools, OSS systems, and ticketing platforms.
• Familiarity with ITIL processes (Incident, Problem, Change, Release).
• Previous experience in a Managed Services / NOC environment is desirable.

Specific skills & technical knowledge:

• Strong technical knowledge of Ericsson RAN and related OSS systems.
• Understanding of 5G SA/NSA architecture, mobility management, and feature activation.
• Working knowledge of RAN performance KPIs, optimization techniques, and troubleshooting methodologies.
• Familiarity with NFVI, Cloud RAN, and IP transport.
• Ability to create and execute scripts/automation for repetitive tasks.
• Strong analytical, troubleshooting, and problem-solving skills.
• Excellent communication and documentation abilities.
• Professional level of English is a must (written and spoken).
