  • Hands-on experience deploying and commissioning Small Cell / HetNet solutions and baseband units.
  • Solid understanding of mobile transport protocols (eCPRI, CPRI), radio access network (RAN) fundamentals, and backhaul aggregation.
  • Proficiency in IP networking fundamentals: IPv4/IPv6 subnetting, QoS/CoS policies, VLANs, and Layer 2/3 transport.
  • Familiarity with network test gear: OTDRs, optical power meters, spectrum analyzers, and Ethernet/10G-100G bit error rate testers (BERT).

Preferred Qualifications

• Industry certifications such as CCNA/CCNP Service Provider, Nokia NRS I/II, or equivalent carrier certifications.

• Experience with automated provisioning tools, NetConf/YANG, and network scripting using Python or Bash.

• Familiarity with Open RAN architectures and cloud-native network functions (CNFs/VNFs).

Key Responsibilities

• Access Network Deployment & Integration:
  • Configure, commission, and maintain OLT platforms (GPON, XGS-PON, NG-PON2) and Optical Network Terminals/Units (ONT/ONU).
  • Design, deploy, and integrate indoor/outdoor 4G LTE and 5G NR Small Cells, Distributed Antenna Systems (DAS), and micro-cell nodes.

• Network Transport & Backhaul
  • Provision and troubleshoot mobile backhaul/fronthaul transport links connecting Small Cells to the Mobile Core (EPC/5GC).
  • Manage Layer 2 switching, Layer 3 routing protocols (BGP, OSPF, ISIS), VLAN tagging (QinQ), and MPLS/Segment Routing implementations across access nodes.

• Performance Optimization & Operations:
  • Conduct RF and optical link budget calculations, optical time-domain reflectometry (OTDR) trace analysis, and power level tuning.
  • Monitor Key Performance Indicators (KPIs) including throughput, latency, jitter, frame loss, and handover success rates.
  • Serve as Level 3 escalation support for chronic network outages, optical degradation, and RF interference issues.

• Vendor & Standards Coordination:
  • Interface with hardware vendors (e.g., Nokia, Huawei, Cisco, CommScope, Ericsson) for firmware validation, patch deployment, and feature testing.
  • Assist in testing and implementing Open RAN (O-RAN) interfaces, CWDM/DWDM mux systems, and timing/synchronization protocols (IEEE 1588v2 PTP, SyncE).

• Annual Leave
• Medical and Hospitalisation Leave
