Hiring || STP Engineer (BLRHYDChennaiDelhi)

Required Skills:

Summary: The Telesys STP Engineer plays a critical role in the deployment configuration and integration of Telesys Signal Transfer Point (STP) platforms within telecom core networks. This position is essential for ensuring robust high-availability SS7 signaling infrastructure that supports seamless interconnection across mobile networks. The engineer will be responsible for designing and maintaining signaling routes optimizing traffic distribution and troubleshooting complex signaling issues. With expertise in SS7 and Diameter protocols the role supports both legacy and evolving 4G/5G architectures enabling smooth interworking between core network elements such as MSC HLR SMSC and IN. The ideal candidate will bring strong technical acumen hands-on experience with STP platforms and a deep understanding of signaling protocols and network optimization in dynamic mission-critical environments.
