About PHNX Securities
https://www.phnxsecurities.com/

PHNX Securities is a next-generation quantitative trading firm, focused on systematic, research-driven strategies. Our approach combines deep market understanding with robust engineering - emphasizing clean execution infrastructure, rigorous backtesting, strict risk controls, and full regulatory readiness.

Our Mission
To combine advanced research, automation, and disciplined risk management to create scalable, repeatable, high-conviction quantitative strategies across global markets.

Role Overview
We are looking for a strong C++ engineer with a passion for performance and low-latency systems to build and optimize the core trading infrastructure at PHNX Securities.
This is a deeply technical engineering role — the primary focus is writing high-performance, production-grade C++ for systems where microseconds matter. You will work on order management, execution, and market data infrastructure that runs live in exchange-connected environments.



A basic understanding of trading systems and market structure is expected, but elite C++ engineering is what this role demands first.

Key Responsibilities
• Design and develop ultra-low-latency trading systems in modern C++ (C++17/20)
• Build and optimize the Order Management System (OMS) — order routing, pre-trade risk checks, execution handling and fills
• Profile, benchmark, and systematically reduce end-to-end latency across application, kernel, and network layers
• Write cache-friendly, lock-free, and memory-efficient code — optimizing at the hardware level including CPU pinning, NUMA awareness, memory alignment, and cache utilization
• Work on kernel bypass and NIC-level optimizations (DPDK, Solarflare)
• Collaborate with quant researchers to productionize strategies and ensure system reliability, determinism, and correctness under real-time production conditions
• Build and maintain market data infrast
