About this role
We are seeking a highly proficient C++ Developer to design, develop, and optimize critical telecom protocol modules within our SMS and Voice Firewall solutions. This role involves building high-performance, low-latency systems for real-time message filtering, fraud detection, and large-scale telecom traffic processing.
Key Responsibilities
●Design, develop, and optimize SMPP and SS7 protocol modules for efficient message routing and filtering.
● Implement high-throughput, low-latency systems for real-time SMS and voice traffic processing.
●Develop scalable solutions leveraging multithreading, advanced memory management, and network programming (TCP/IP, SCTP).
● Ensure system resilience through robust failover mechanisms, security controls, and adherence to telecom standards.
● Troubleshoot and optimize protocol-level issues using tools such as Wireshark, GDB, and Valgrind.
● Collaborate with cross-functional teams to enhance system performance, scalability, and reliability.
Required Skills & Competencies
●Strong proficiency in C++ (modern standards) on Linux environments, including STL, Boost, and multithreading.
● In-depth knowledge of telecom protocols: SMPP, SS7, and SIGTRAN (M3UA, SCCP, MAP, CAP), along with SIP.
● Solid understanding of networking concepts and performance optimization (TCP/IP, SCTP, load balancing, caching with Redis).
● Experience with relational and NoSQL databases such as MySQL, PostgreSQL, Cassandra, and MongoDB.
● Expertise in debugging, profiling, and performance tuning using tools like GDB, Valgrind, and Wireshark.
● Proficiency in scripting languages such as Python and Bash for automation and testing.
● Experience with version control systems (Git, SVN).
● Familiarity with Agile development practices and tools such as Jira and Confluence.
Preferred Qualifications
● Experience working on SMS Firewall, telecom fraud detection, or telecom security platforms.
● Knowledge of Diameter protocol and real-time anomaly detection systems.
● Relevant certifications in C/C++ development or system programming.
