Description

Low-Latency C++ Engineer - Systematic Trading
We're looking for a seasoned low-latency engineer to help push the boundaries of speed and efficiency across our trading systems. You'll be working at the intersection of software and hardware - tuning every layer of our stack, from the Linux kernel to our custom C++ frameworks, ensuring our trading infrastructure runs at nanosecond precision.

This is a hands-on, performance-driven engineering role within a team that obsesses over every CPU cycle, cache miss, and network packet.

What You'll Do

• Architect, implement, and refine ultra-low-latency C++ systems for execution, market data processing, and internal infrastructure.
• Analyze and optimize performance across compute, memory, cache, and networking layers using advanced profiling and benchmarking tools.
• Collaborate with FPGA, hardware, and network engineering teams to design holistic, cross-stack optimizations.
• Continuously improve our real-time telemetry, logging, and monitoring systems to surface microsecond-level insights.
• Experiment with kernel tuning, driver parameters, and CPU isolation to squeeze out every bit of performance.

What We're Looking For

• 5+ years of hands-on experience building and optimizing latency-sensitive C++ systems (C++17/20 preferred).
• Strong understanding of modern CPU architecture, instruction pipelines, NUMA, cache coherency, and memory management.
• Deep expertise with Linux internals - from kernel configuration and interrupt handling to low-level performance profiling (perf, eBPF, ftrace, etc.).
• Experience with lock-free data structures, high-performance networking (TCP/UDP/multicast), and concurrency models.
• Familiarity with RDMA, DPDK, or other kernel-bypass networking stacks is a plus.
• Comfortable working closely with FPGA, infrastructure, and research teams to optimize full-stack latency.
• A scientific mindset - you measure, test, and iterate to drive measurable latency gains.

We look forward to hearing from you!
