Senior C++ Developer (Low-Latency Market Data)

Salary: $110,000 - 140,000 per year Requirements:

• Strong proficiency in modern C++ (C++17/20 or later)
• Solid understanding of concurrency and synchronization, including lock-free or low-lock patterns, atomics, and memory models
• Proven experience building performance-critical, real-time, or low-latency systems, such as networking, trading systems, telemetry, or gaming engines
• Strong computer science fundamentals, including data structures, algorithms, memory management, and optimization
• Practical experience with Linux systems programming, including sockets, epoll/select, threads, memory management, and CPU affinity
• Experience with profiling, benchmarking, and performance analysis tools such as perf, valgrind, flame graphs, and CPU or memory profilers
• Proficiency with Git and standard build systems such as CMake or Ninja
• Strong problem-solving skills and attention to detail, with the ability to work in a fast-paced environment
• Experience with kernel-bypass or user-space networking technologies such as DPDK, RDMA, VMA, or Solarflare/OpenOnload is helpful but not required
• Experience in financial markets, market data distribution, order routing, or exchange connectivity is a plus
• Familiarity with market data protocols such as FIX, MDP, ITCH, or proprietary exchange feeds is a plus
• Experience with multicast, low-latency networking, and clock synchronization such as PTP is beneficial
• Exposure to hardware-aware optimization, including NUMA, cache optimization, vectorization/SIMD, or CPU pinning, is beneficial
• Experience with monitoring and telemetry for high-performance systems, including latency histograms, throughput metrics, or SLAs, is beneficial
• Familiarity with scripting languages such as Python or Bash for tooling and automation is beneficial

• Design, implement, and maintain high-performance C++ services that handle high message rates and low-latency workloads
• Optimize existing components for latency, throughput, and CPU and memory efficiency
• Develop and tune networking, messaging, and I/O layers to reliably process large data volumes
• Profile and debug performance issues across application, operating system, and network layers
• Collaborate with quantitative, trading, and infrastructure teams, or analogous business and technology teams, to turn requirements into robust technical solutions
• Write clean, production-quality code with appropriate tests and documentation
