Job summary

NDA Trading Firm is seeking a senior, hands-on C++ engineer to design, build, and optimize the low-latency hot path for automated/electronic trading in modern C++ (C++17/20). You will own market-data infrastructure and FIX-based order flow, collaborating with traders and quants in a fully remote engagement.

The role emphasizes lock-free programming, high-performance profiling, and kernel-bypass networking to reduce latency.

Qualifications

• 6+ years of professional C++ engineering in production low-latency systems.
• Modern C++: C++17 minimum, C++20 preferred.
• Experience in traditional financial services with market-data exposure.
• Hands-on with lock-free programming, multicast, networking, and profiling.

Responsibilities

• Design, build, and optimize the low-latency hot path for automated trading in modern C++ (C++17/20).
• Build and maintain market-data infrastructure: feed handlers, ticker plant, order-book construction, and normalization.
• Implement exchange connectivity and FIX-based order flow, including smart-order-routing components.
• Drive down tick-to-trade latency using lock-free data structures, NUMA-aware design, and kernel-bypass networking.
• Profile, measure, and eliminate latency and jitter across the full stack.
• Translate strategy and execution needs from traders and quants into production code.
• Own components end-to-end: reliability, observability, and incident response.
