Software Engineer (OAM )

Responsibilities:

• Analyze customer requirements and translate them into comprehensive design specifications, facilitating workload estimation and task allocation

• Participate in system-level architecture discussions, ensuring alignment with 3GPP, ORAN, AI-RAN and vendor-specific requirements

• Define northbound/southbound interface workflows for OSS, EMS, and NMS interactions

• Design and enhance OAM software components for 5G/6G AI-RAN nodes (SMO, RIC, gNB-CU, gNB-DU, O-eNB, RU, etc.)

• Develop scalable software modules for FCAPS functions (Fault, Configuration, Accounting, Performance, Security) and optimize runtime resource usage and improve manageability of RAN nodes

• Integrate OAM modules with 4G/5G RAN product baselines, including CU/DU software stacks, O-Cloud platforms and O-RU

• Ensure compatibility between management layers (EMS/NMS/SMO/BBU) and RAN nodes using standards such as NETCONF/YANG, RESTCONF, O1/O2 interfaces

• Develop verification strategies and test plans for end‑to‑end OAM functionality

• Execute integration tests, regression tests, and system-level validation for new software releases

• Automate verification flows using scripting languages (Python, Shell, or Robot Framework)

• Diagnose defects using logs, traces, pcap, and system KPIs; debug issues across distributed systems

• Work closely with system engineers, RAN protocol developers, DevOps teams, and QA

• Support customer adaptations, interoperability testing (IOT), and field issue resolution

• Contribute to technical documentation, design/integrate/verify specs, and system interface definitions

Qualifications:

• Bachelor's degree or higher in Computer Science, Wireless Communication, or Electronic Engineering

• 2+ years work or project experience in telecom or wireless network software development

• Strong proficiency in C/C++ or JAVA for backend/service development, Python/Shell automation and Linux system programming/debugging

• Practical knowledge of FCAPS management principles and implementation

• Hands-on experience with 4G/5G RAN architectures (3GPP 36.xxx/38.xxx series)

• Hands-on experience with OAM/EMS/OSS systems in telecom networks

• Hands-on experience with Linux network programming and NETCONF/YANG, SNMP, REST, gRPC or related management protocols
