Below is the JD
Design and Implement 5G SBA Services: Develop microservice-based components such as AMF, SMF, PCF, NRF, and others in alignment with 3GPP standards (e.g., TS 23.501, 29.500).
RESTful API Development: Build and manage REST APIs for inter-NF (Network Function) communication. Ensure API compliance with OpenAPI specs and 3GPP-defined message flows.
Cloud-Native Deployment: Use container technologies like Docker and Kubernetes to deploy services in scalable, resilient environments—whether on public cloud (AWS, Azure) or private 5G telco clouds.
Performance and Reliability: Ensure high performance, scalability, and reliability of network services. Optimize services for low latency and high throughput.
CI/CD and DevOps: Integrate code into automated pipelines for continuous integration and deployment. Collaborate with DevOps teams to ensure smooth service rollouts and updates.
Testing and Debugging: Write unit, integration, and system-level tests. Debug real-time issues in simulated or live test environments.
Documentation and Standards Compliance: Keep thorough documentation of designs, APIs, and implementations. Maintain compliance with evolving 3GPP standards.
