Jio – Graduate Engineer Trainee

The Graduate Engineer Trainee position at Jio is an entry-level opportunity for engineering graduates interested in building a career in telecommunications, mobile networks, core network operations, and network engineering. The role is based in Mumbai and provides fresh graduates with practical exposure to the technologies and operational processes that support large-scale telecom services. The selected candidate will work with experienced network engineering teams to support core network architecture, operations, service monitoring, subscriber provisioning, authentication, charging, interconnect, and roaming activities. The position is particularly suitable for fresh B.E. or B.Tech graduates who have a foundational understanding of telecom networks and want to develop their technical expertise within a large telecommunications organization. Jio's core network environment offers exposure to multiple generations of mobile technologies, including 2G, 3G, and 4G networks.

A significant part of the Graduate Engineer Trainee role involves network monitoring, troubleshooting, testing, and operational support. Trainees will assist in monitoring core network KPIs and service parameters, analyzing call flows and signalling issues, troubleshooting network alarms and outages, and supporting subscriber provisioning processes. The role also involves validating authentication and charging systems, participating in interconnect and roaming testing, and coordinating with related network teams. These responsibilities provide an opportunity to understand how telecom services operate at the core-network level and how different components work together to maintain connectivity and service quality. Candidates will also gain practical exposure to network upgrades, new node rollouts, configuration changes, and technical documentation while developing the ability to diagnose and resolve network-related issues.

The position also emphasizes collaboration between different technical teams involved in maintaining Jio's telecommunications infrastructure. Graduate trainees will coordinate with Radio Access Network (RAN), transport, device, and product teams while supporting network requirements and operational activities. They may contribute to the development of requirements for mobile connectivity capabilities, assist with upgrades and new network-node deployments, and document configurations and technical changes. A strong analytical approach is important because telecom engineers frequently need to interpret network KPIs, investigate signalling behavior, identify potential service issues, and support troubleshooting during outages. For fresh engineering graduates, this role provides a structured environment to develop telecom engineering knowledge, practical troubleshooting skills, communication abilities, and an understanding of large-scale network operations.
