Responsibilities of a Radio Access Network Engineer:
Responsible for communicating with cross-functional Software development Teams to create processes related to automation to reduce manual work or to build software products and automation tools related to RAN Engineering.
Coordinate with cross-functional teams i.e RF, Microwave, Site Acquisition and Backhaul, to design, develop, and troubleshoot wireless communication systems and automated tools that meet performance, coverage, and compliance standards.
Design and develop Telecommunication networks and telco cloud solutions based on 3GPP and ETSI standards.
Design Telco cloud RAN solution based on Kubernetes, OpenStack, OpenShift and Public Cloud (AWS, Microsoft AODS).
Design and deliver 4G/5G- 5G NSA,5G SA/ Volte/Vowifi/VoNR/Vo5G solutions for multiple CSPs.
Plan and manage 2G, 4G, and 5G site installation, configuration, commissioning, and testing of power equipment, and troubleshoot alarms in the eNB/gNB, such as CPRI and VSWR alarms.
Analyze 4G, 5G L2/L3 call flows using PCAPs and gNB traces.
Perform radio network planning and dimensioning activities including coverage prediction, frequency planning, and capacity analysis.
Conduct site surveys of 4G/5G colocation sites and inspect them according to approved designs.
Integrate and manage the O-RAN components Radio Unit (RU), Distributed Unit (DU), and Central Unit (CU).
Create and troubleshoot scripts for Antenna/RRU swaps, RET validations, external alarms, frequency retunes, and site reconfigurations.
Perform 1G to 10G backhaul upgrades and troubleshooting.
Validate and execute MOPs and network activities.
Test new 4G/5G RAN features and test cases to evaluate functional performance and failover capabilities.
Utilize Big Data Analytics with Python, and Tableau for operational modeling, anomaly detection, task automation, and zero-touch network performance management.
Support migration activities for legacy RAN systems to virtualized and cloud-native RAN architecture.
Provide support for the lifecycle management of RAN components, including software upgrades, patching, and performance tuning.
Qualifications for Radio Access Network Engineer Role:
US Master’s degree or foreign equivalent degree in Electrical Engineering or a related field, plus one (1) year of experience in Electrical Engineering.
