Job summary

Syanxg Technologies Pte Ltd is seeking an experienced engineer to design and implement OAM software components for 5G/6G AI-RAN nodes, and to develop FCAPS modules and verification strategies. You will work on integration with 4G/5G baselines, cloud-native platforms, and management interfaces (EMS/NMS/SMO).

Strong collaboration and English communication are essential. The role requires hands-on experience with Linux, NETCONF/YANG, and cloud-native tooling, plus ability to analyze requirements

Qualifications

• Bachelor's degree or higher in Computer Science, Wireless Communication, or Electronic Engineering.
• 2+ years of telecom or wireless network software development experience.
• Proficiency in C/C++ or JAVA for backend/service development; Python/Shell for automation; Linux system programming.
• Experience with FCAPS management principles.
• Hands-on experience with 4G/5G RAN architectures (3GPP 36.xxx/38.xxx).
• Hands-on experience with OAM/EMS/OSS systems in telecom networks.
• Experience with Linux programming and NETCONF/YANG, SNMP, REST, gRPC.
• Familiarity with Cloud-native tech (Docker, Kubernetes, CI/CD like Jenkins/Gitlab).
• Strong written and verbal English; collaboration and problem solving.

Responsibilities

• Analyze customer requirements and translate them into design specs for workload estimation and task allocation.
• Participate in system-level architecture discussions aligning with 3GPP, ORAN, AI-RAN and vendor needs.
• Define northbound/southbound workflows for OSS, EMS, and NMS interactions.
• Design and enhance OAM software components for 5G/6G AI-RAN nodes (SMO, RIC, gNB-CU/DU, O-eNB, RU).
• Develop scalable FCAPS modules and optimize runtime resource usage.
• Integrate OAM modules with 4G/5G baselines, CU/DU stacks, O-Cloud, O-RU.
• Ensure compatibility between EMS/NMS/SMO/BBU and RAN nodes using NETCONF/YANG, RESTCONF, O1/O2.
• Develop verification strategies and test plans for end-to-end OAM.
• Execute integration, regression, and system tests for new releases.
• Automate verification with Python, Shell, or Robot Framework.
• Diagnose defects from logs, traces, pcap and KPI data.
• Collaborate with system engineers, RAN developers, DevOps, and QA.
• Support customer adaptations, interoperability testing, and field issue resolution.
• Contribute to technical documentation and interface specs.
