Job Description
We are seeking a skilled telecom software engineer to join our team. The responsibilities include:
1. Design and Implementation of 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).
2. RESTful API Development: Build and manage REST APIs for inter-NF (Network Function) communication, ensuring API compliance with OpenAPI specs and 3GPP message flows.
3. 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.
4. Performance and Reliability: Ensure high performance, scalability, and reliability of network services, optimizing for low latency and high throughput.
5. CI/CD and DevOps: Integrate code into automated pipelines for continuous integration and deployment. Collaborate with DevOps teams for smooth service rollouts and updates.
6. Testing and Debugging: Write unit, integration, and system tests. Debug real-time issues in simulated or live environments.
7. Documentation and Standards Compliance: Maintain thorough documentation of designs, APIs, and implementations, ensuring compliance with evolving 3GPP standards.
