12 Ims Architecture Jobs

As a candidate for this role, you are expected to possess a deep expertise in 4G core and IMS architecture, with a strong understanding of VoLTE, WIFI, and 3GPP standards compliance. Your knowledge in these areas will be crucial for the successful implementation and maintenance of related systems. In addition to the must-have requirements, any experience or familiarity with 5G core evolution, cloud native deployments, and multi-vendor network integration would be advantageous. Being able to work with these technologies can further enhance the efficiency and effectiveness of our network operations.,

We are searching for a highly skilled Python Automation Engineer with expertise in 5G networks and IMS (IP Multimedia Subsystem) testing to become a part of our dynamic team. The perfect candidate will have practical experience in automating test scripts, telecom protocol testing, and ensuring the quality, performance, and resiliency of 5G/4G network functions. As a Python Automation Engineer, you will have a significant role in the validation of IMS architecture, automation of test cases, and performance verification of network functions. Your responsibilities will include developing and maintaining automated test scripts utilizing Python, TCL, and BDD to validate IMS functionalities and 5G/4G network features. You will design, execute, and enhance test cases for telecom protocols such as SIP, Diameter, MAP, SBI, RTP, and DNS. Additionally, you will be performing integration, performance, and resiliency testing of IMS applications and 3GPP nodes like HLR, HSS, UDM, SMSC, PGW, SMF, and MME. Building and maintaining automation frameworks to streamline test execution and reporting, conducting manual and automated testing for IMS-based services such as VoLTE, VoWiFi, and RCS, simulating network traffic, and testing performance under various conditions using tools like IxLoad, Landslide, and EXFO are crucial aspects of the role. Furthermore, you will be responsible for debugging and troubleshooting issues at both software and network levels using logs, stats, Grafana, and protocol analyzers like Wireshark. Your collaboration with software engineers, network engineers, and DevOps teams to resolve issues and enhance system performance is essential. Integrating automated tests into CI/CD pipelines using Kubernetes, Flux/GitOps, testing system resiliency, geo-redundancy, hardware failure scenarios, and conducting chaos testing will also be part of your duties. To excel in this role, you must possess strong programming skills in Python, along with experience in TCL and BDD. A solid understanding of IMS and its components (HSS, PCRF, CSCF), practical experience with 5G/4G networks and 3GPP nodes, deep knowledge of telecom protocols (SIP, Diameter, MAP, SBI), experience with automation tools and frameworks like Robot Framework, Selenium, or pytest, proficiency with network simulators and analyzers, hands-on experience with Kubernetes, GitOps (Flux), and CI/CD pipelines, strong networking knowledge, experience in performance/load/stress testing and debugging at scale, familiarity with monitoring tools and bug tracking tools, understanding of telecom standards and IMS-based services, as well as excellent communication skills and ability to work in a collaborative environment, are crucial.
