Telecom Engineer (Telesys STP)

Summary: The Telesys STP Engineer is responsible for deploying, configuring, and integrating Telesys Signal Transfer Point platforms within telecom core network environments, emphasizing SS7 signalling and routing optimization. The role requires extensive hands-on experience with STP nodes and a strong understanding of various signalling protocols. The engineer will also support legacy SS7 scenarios and ensure high availability of STP resources. This position demands a comprehensive knowledge of telecom architectures and modern deployment practices.

Key Responsibilities:

• Hands on experience in installing, configuring, and commissioning Telesys STP nodes
• Configure point codes, linksets, routes, and Global Title Translation (GTT)
• Configure and manage SS7 signalling links including A links, B links, and C links
• Prepare MOPs and implementation artifacts for software upgrades and changes
• Integrate STP with core network elements such as MSC, HLR, SMSC, IN, and signalling gateways
• Support Legacy SS7 and interworking scenarios based on customer requirements
• Strong working knowledge of the SS7 protocol stack:
• MTP Level 1/2/3
• SCCP (connectionless & connection oriented)
• TCAP (basic operations)
• Handle E.164, E.212, and E.214 numbering plans
• Implement routing logic based on IMSI, MSISDN, and GT patterns
• Analyze and troubleshoot signalling failures using traces and logs
• Perform protocol level debugging including SCCP and TCAP decoding
• Use tools such as Wireshark/tcpdump for signalling analysis
• Optimize routing tables and signalling load distribution
• Perform health checks, capacity planning, and performance analysis
• Ensure high availability and optimal utilization of STP resources
• Understanding of 2G/3G/4G/5G signalling architectures, particularly:
• MAP signalling
• MAP Diameter interworking concepts
• Familiarity with Diameter signalling in legacy to LTE/5G evolution scenarios
• Experience with bare metal, virtualized, and cloud platforms such as KVM, VMware, Kubernetes based CNF
• Exposure to CI/CD pipelines and DevOps practices

Key Skills:

• 8+ years of experience in telecom engineering
• Expertise in SS7 signalling and routing optimization
• Hands-on experience with Telesys STP nodes
• Strong knowledge of SS7 protocol stack (MTP, SCCP, TCAP)
• Experience with E.164, E.212, and E.214 numbering plans
• Ability to analyze and troubleshoot signalling failures
• Familiarity with 2G/3G/4G/5G signalling architectures
• Experience with cloud platforms and CI/CD practices
