Senior C\C++ Engineer

In this role, you will contribute to a large-scale network and real-time communications monitoring platform used in carrier and enterprise environments., * Maintain and extend the C routing-and-session-detection engine, including protocol decoders for SIP and RTP/RTCP at the wire level

• Work with the C++/CORBA management plane, including distributed-object/middleware components
• Diagnose and resolve issues using libpcap/Wireshark captures and memory-safety tooling (AddressSanitizer, Valgrind, fuzzing)
• Support and integrate with SBC vendors (Oracle/Acme, Sonus/Ribbon, AudioCodes, Avaya, Polycom) where applicable
• Reconstruct and modernize builds for legacy C/C++ codebases (e.g., migrating to CMake or equivalent) and help build out CI pipelines
• Operate and support the platform’s PostgreSQL datastore
• Collaborate across the six subsystems (C engine, C datastore, C++/CORBA management plane, Java web tier) to keep the platform stable on FreeBSD

• 6+ years of experience as С\С++ Engineer
• Strong hands-on experience with C and C++, including legacy codebases and older versions of C/C++
• Strong understanding of Linux/Unix internals; FreeBSD/BSD experience would be a significant advantage
• Strong networking background, including TCP/IP, UDP, and protocol/packet-level troubleshooting
• Experience with distributed and high-performance systems, ideally systems processing significant volumes of network traffic
• Proven experience with reverse engineering / discovery of large existing systems with limited documentation and limited knowledge transfer
• Strong debugging and performance troubleshooting skills: memory issues, crashes, bottlenecks, network-related problems, etc
• Upper-intermediate or higher level of English
• Ability to go beyond reading code and systematically reconstruct the architecture: identify critical flows, component dependencies, business-critical vs. obsolete functionality, and document the acquired knowledge
• Strong ownership mindset and ability to work autonomously
• Experience with CORBA/RPC or similar legacy IPC/distributed communication technologies (would be a plus)
• Experience with SIP, RTP, H323, VoIP, or real-time communications (is highly desirable)
