Senior C++ developer - Network Systems

6 8 years of experience as C++ Engineer Hands-on C/C++ (C++14 minimum) proven experience building high-throughput, low-latency systems: packet processing, real-time protocol state machines, or embedded network applications. Python scripting for tooling, test automation, and operational scripts. Strong mastery of memory management, lock-free data structures, CPU cache optimization, and production profiling tools (perf, valgrind, sanitizers) applies to the C++ core. Experience with CMake build systems and Conan package management. Experience running and debugging C++ services inside Docker containers.
