IMS Developer – Job Opportunity in Delhi/Gurgaon (6–8 Years’ Experience)

Are you an experienced IMS Developer with a passion for cutting-edge telecom technologies and a solid understanding of 4G Core, CUPS Architecture, and cloud-native deployments? We are looking for a seasoned professional who can deliver impactful solutions in the rapidly evolving IMS (IP Multimedia Subsystem) space. This opportunity is ideal for skilled developers with expertise in C/C++, telecom protocols, and modern software architecture patterns like VNF/CNF and microservices. The role is based in Delhi or Gurgaon and requires 6–8 years of relevant experience.

About the Role

Join our forward-thinking tech team as an IMS Developer and contribute to cutting-edge telecom solutions. This role involves designing, developing, and maintaining robust IMS network solutions. The ideal candidate must have in-depth knowledge of 4G Core systems and IMS protocols, hands-on experience in system-level programming using C/C++, and familiarity with cloud-native infrastructure and DevOps tools.

Key Responsibilities

  • Design and implement IMS Network solution modules aligned with 3GPP standards.

  • Develop scalable and optimized code using C/C++, ensuring thread safety and efficient memory usage.

  • Build and troubleshoot multi-threaded applications within a Linux environment.

  • Analyze and debug performance issues using development tools such as GDB, Strace, and static/dynamic code analyzers.

  • Collaborate with cross-functional teams to integrate IMS components into larger telecom solutions.

  • Implement support for telecom protocols such as SIP, RTP, Diameter, TCP/IP, UDP, and IPC.

  • Manage relational and non-relational databases required for telecom application backends.

  • Participate in the full software development lifecycle, including planning, development, testing, and deployment.

  • Ensure IMS solutions comply with 3GPP call flow specifications and maintain compatibility across IMS/4G Core elements.

  • Work with modern network architectures including VNF (Virtual Network Function), CNF (Cloud-Native Functions), and microservice-based deployments.

Required Skills & Experience

  • Minimum of 4+ years of hands-on experience in IMS network solution development.

  • Strong programming skills in C/C++ with a deep understanding of multi-threading, concurrency, and memory management.

  • Experienced in Linux operating systems with practical expertise in low-level programming and debugging utilities.

  • Comprehensive knowledge of 4G EPC Core elements, IMS architecture, and CUPS (Control and User Plane Separation) framework.

  • Experience with communication protocols including SIP, RTP, Diameter, TCP/IP, UDP, IPC, and socket programming.

  • Familiar with database design principles—both relational (e.g., MySQL, PostgreSQL) and non-relational (e.g., MongoDB, Cassandra).

  • Good grasp of 3GPP call flows, including session initiation, media negotiation, and QoS management.

  • Practical experience with C development tools including debugging and code optimization tools.

  • Exposure to DevOps tools, cloud platforms, SDN, and virtualized infrastructure.

Preferred Qualifications

  • Understanding of cloud-native technologies such as Kubernetes, Docker, Helm, and CI/CD pipelines.

  • Knowledgeable in Software-Defined Networking (SDN) and Network Function Virtualization (NFV) technologies.

  • Experience in microservice development and deployment strategies in modern telco-cloud environments.

  • Knowledge of EPC elements (e.g., PGW, SGW, MME), VoLTE architecture, and integration with IMS components.

  • Contributions to open-source IMS projects or relevant telecom platforms is a plus.

Educational Qualification

  • Bachelor of Engineering (B.E./B.Tech) in Computer Science, Electronics & Communication, Information Technology, or a related field.
