Project Description: • We are looking for a C++ engineer to design and build high-performance, low-latency applications that process large volumes of real-time data. You will work on systems where microseconds and throughput matter, optimizing every layer from algorithms and data structures to networking and OS interaction., • Compensation in NYC is 120,000–140,000 USD gross per year, based on the interview results. Responsibilities: • Design, implement, and maintain high-performance C++ services handling high message rates and low-latency workloads., • Optimize existing components for latency, throughput, and CPU/memory efficiency., • Develop and tune networking, messaging, and I/O layers to handle large data volumes reliably., • Profile and debug performance issues at the application, OS, and network levels., • Collaborate with quantitative, trading, and infrastructure teams (or analogous business/tech teams) to translate requirements into robust technical solutions., • Write clean, production-quality code with appropriate tests and documentation., • Participate in code reviews, design discussions, and continuous improvement of engineering practices. Mandatory Skills Description: • Strong proficiency in modern C++ (C++17/20 or later), • Hands-on experience with Market Data, • Solid understanding of concurrency and synchronization (lock-free/low-lock patterns, atomics, memory models, etc.)., • Proven experience building performance-critical, real-time, or low-latency systems (e.g., networking, trading systems, telemetry, gaming engines, or similar)., • Strong knowledge of computer science fundamentals: data structures, algorithms, memory management, and optimization., • Practical experience with Linux systems programming (sockets, epoll/select, threads, memory management, CPU affinity, etc.)., • Experience using profiling, benchmarking, and performance analysis tools (e.g., perf, valgrind, flame graphs, CPU/memory profilers)., • Proficiency with version control (Git) and standard build systems (CMake, Ninja, etc.)., • Excellent problem-solving skills and attention to detail; ability to work in a fast-paced environment. Nice-to-Have Skills Description: • Experience with kernel bypass or user space networking technologies (e.g., DPDK, RDMA, VMA, Solarflare/OpenOnload)—helpful but not required., • Experience in financial markets, market data distribution, order routing, or exchange connectivity., • Familiarity with common market data protocols (e.g., FIX, MDP, ITCH, proprietary exchange feeds) is a plus., • Experience with multicast, low-latency networking, and clock synchronization (e.g., PTP)., • Exposure to hardware-aware optimization (NUMA, cache optimization, vectorization/SIMD, CPU pinning)., • Experience with monitoring/telemetry for high-performance systems (latency histograms, throughput metrics, SLAs)., • Familiarity with scripting languages (e.g., Python, Bash) for tooling and automation., • KDB+, • Data Analysis with Python (PyTorch, pandas, arrow) Languages: • English: B2 Upper Intermediate
