Role: Service Based Architecture

Location: Stevenage -UK

Mode: Hybrid

Type: Contract

:

5G Core Network -designing, developing cloud-native network functions like AMF, SMF, PCF, NRF, and others in alignment with 3GPP standards (e.g., TS 23.501, 29.500 ) Build and manage REST APIs for inter-NF (Network Function) Experience in container technologies like

Docker

and

Kubernetes

to deploy services in scalable, resilient environments--whether on public cloud (AWS, Azure) or private 5G telco clouds Integrate code into automated pipelines for continuous integration and deployment. Collaborate with DevOps teams to ensure smooth service rollouts and updates

Skills:

6+ years of hands-on development experience with 5G SBA network functions (e.g., AMF, SMF, NRF, PCF, UDM) Strong programming skills in languages such as Go, Java, or C++ Proficient in building microservices and working with REST/gRPC APIs Experience in

Docker

and

Kubernetes

in deploying services over public or private clouds Solid understanding of 3GPP specs (especially TS 23.501, 23.502, 29.500+ series Experience with network function virtualization (NFV) and service mesh (e.g., Istio) will be plus*.

Below is the :

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.
