Job Description

We are seeking an exceptional Low-Latency C++ Software Engineer to join our High-Frequency Trading technology team. You will design and build the core trading infrastructure that executes millions of orders per day at microsecond speeds. This is a highly technical, high-impact role at the intersection of systems programming and quantitative finance.

Responsibilities

Design, develop, and optimize ultra-low-latency trading systems in modern C++ (C++17/20)
Build and maintain order management systems (OMS) , execution engines, and market data handlers
Profile and tune code to achieve sub-microsecond latency across the full trading stack
Develop kernel bypass networking solutions using DPDK, Solarflare OpenOnload, or similar technologies
Collaborate with quant researchers to implement and deploy alpha signals and execution algorithms
Optimize for cache efficiency , branch prediction, and CPU pipeline utilization
Integrate with exchange co-location environments and FIX/ITCH/OUCH protocols
Monitor production systems and participate in on-call rotations

Required Qualifications

5+ years of professional C++ development experience (HFT or systems programming preferred)
Deep expertise in modern C++ (templates, move semantics, lock-free programming, memory models)
Strong understanding of computer architecture : CPU caches, NUMA, branch prediction, vectorization (SIMD/AVX)
Experience with lock-free and wait-free data structures (atomic operations, memory ordering)
Proficiency with Linux performance tooling : perf, flamegraphs, vtune, valgrind, strace
Solid grasp of TCP/IP networking and the Linux network stack
Ability to reason about latency at nanosecond granularity
