Senior Low Latency Kernel Engineer (C++/Linux)
Want to work where nanoseconds matter?
We're partnering with a top-tier quantitative trading firm seeking a Low-Latency Kernel Engineer to push the limits of Linux, networking, and hardware performance. This is a deeply technical role focused on kernel tuning, CPU and memory optimization, network stack performance, and ultra-low-latency C++ development. You'll work directly with FPGA, infrastructure, and hardware teams to eliminate bottlenecks across the entire stack.
What you'll be doing:
