We seek a Senior C/C++ Backend Engineer with deep expertise in high-concurrency, low-latency, highly reliable core infrastructure. Key domains: High-Performance Network Gateways (million+ concurrent connections, zero-copy I/O, coroutines/I/O multiplexing); MMO Game Servers (state/frame sync, distributed sessions, hot-reload, seamless scaling); Database Kernel Development (storage/query engines, transactions, WAL, B+ trees); Real-Time Streaming (RTMP/WebRTC, AV codecs, ABR, edge coordination); Low-Layer Storage (Linux kernel modules, Direct I/O/mmap, NVMe/SSD optimization, RAID/erasure coding). Requires 5+ years of Linux C/C++ experience, mastery of OS fundamentals (scheduling, memory/virtual memory, lock-free programming), network stacks (TCP/UDP, epoll/kqueue, SO_REUSEPORT), and performance tuning (perf, eBPF, flame graphs, cache alignment, NUMA). Proficiency in C++17+ is mandatory; gdb, valgrind, ASan, TSan required.
