What youll work on

• Design and implement low-latency, high-throughput C++ services used in real-time environments

• Build multithreaded systems that process large volumes of events with predictable performance

• Optimize memory usage, CPU cache behavior, and lock contention

• Debug production issues using core dumps, perf, valgrind, and flame graphs
• Collaborate with quant, trading, or platform teams to turn complex requirements into efficient systems

What were looking for

• Strong, modern C++ (C++14/17/20) experience in production systems

• Solid understanding of multithreading, lock-free programming, and concurrency primitives
• Experience tuning performance on Linux (scheduler behavior, NUMA, memory allocators)
• Comfortable reasoning about data structures, algorithms, and system trade-offs
• Experience with networking (TCP/UDP), messaging, or real-time data flows is a big plus
