Job description

Role Overview

We are looking for an enthusiastic engineer to join the global delivery team working on deployment and end-to-end testing of the cloud-native policy application (PCRF/PCF). Working in a CaaS environment, the engineer prepares deployment inputs, integrates the policy node with its peers across 4G and 5G, writes and validates policy rule sets, and runs the call-flow testing that proves the solution in the customer network.

Key Responsibilities

• Understand PCRF (Policy and Charging Rules Function) functionality and its interfaces within 4G and 5G call

flows.

• Understand PCRF dimensioning and prepare the input files (JSON / Helm) for cloud-native deployment operator-based, tool-based or manual.

• Understand the network topology and integrate the PCRF with peer nodes.
• Apply 4G Diameter and 5G HTTP/2 protocol knowledge to execute call-flow testing.
• Build the logical configuration required for first call in the network and write the logic that creates policy rules.
• Design and develop topology and rule sets for the PCRF/OCS solution in line with customer requirements.
• Perform configuration audits and document the delivered configuration.
• Work flexibly across time zones as part of a global delivery team based in India.

Mandatory Technical Skills

• Policy architecture: knowledge of Policy/PCRF architectures and interworking.
• Traffic management: strong knowledge of mobile data traffic management technologies and solutions (PCRF, PCEF, OCS) and of mobile internet architectures, services and associated protocols — particularly Diameter and HTTP/2.

• Interfaces: experience with 4G and 5G policy interfaces — Gx, Gy, Sy, N7, N40, N28 — on PCRF and OCS products and platforms.

• Cloud architecture: CaaS, CNF/VNF, Kubernetes (containers/Docker) and OpenShift.
• Deployment: installation, integration and configuration of telecom core nodes (PCRF) on cloud architecture; PCRF + OCS solution deployment in virtualised, OpenStack or cloud environments.

• Network knowledge: in-depth technical knowledge of 4G, 5G and mobile data and voice networks, architectures

and services.

• Linux and scripting: basic shell scripting and Linux experience — OS installation, administration and troubleshooting.

Desirable — Added Advantage

• Hands-on experience with Nokia NPC-Policy.
• Nokia PCRF + OCS solution deployment in a virtualised, OpenStack or cloud environment.
• Charging and OCS rating/ratings-plan exposure.
• Automation of deployment inputs and configuration audits (Python, Ansible, Helm templating).
• Experience presenting solutions to a large, predominantly technical audience.

Qualifications and Competencies

• B.E. / B.Tech in Electronics, Telecommunications, Computer Science or an equivalent discipline.
• Highly proficient written and spoken communication skills.
• Excellent cross-functional communication, co-ordination and negotiation skills.
• Good consultation skills, with the ability to drive solutions in line with customer requirements.
• Good presentation skills — comfortable addressing a large, predominantly technical audience.
• Ability to think outside the box in order to create mobile internet and mobile broadband traffic management

solutions.

• Self-starter with initiative, enthusiasm and a positive 'can do' attitude.
• Willingness to work flexible hours across global customer time zones and to travel as per business requirements.
