Software Engineer — Low-Latency Systems

The Role

You will build and own components of the trading stack where nanoseconds are budgeted line-by-line: feed handlers, order gateways, matching-engine simulators, and the lock-free plumbing between them. Your code touches every order the firm sends.

What You'll Do

• —Design and optimize C++ services on the tick-to-trade critical path
• —Profile and eliminate latency at the level of cache lines and syscalls
• —Build deterministic replay and simulation tooling for exchange protocols
• —Own reliability: your systems fail loudly, safely, and almost never

What We Require

• —Expert-level modern C++ (or Rust) and deep systems knowledge
• —Understanding of kernel bypass networking, NUMA, and lock-free design
• —A track record of measuring before optimizing

Nice to Have

• —FPGA or kernel development experience
• —Exchange protocol experience (ITCH/OUCH, FIX, SBE)
