Job Description

Salary: $95,000 - 134,000 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.
• Familiarity with FPGA, colocation, or co-location.
• Proven experience building performance-critical, real-time, or low-latency systems, such as networking, trading systems, telemetry, or gaming engines.
• Strong knowledge of 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, or CPU and memory profilers.
• Proficiency with Git and standard build systems such as CMake or Ninja.
• Excellent 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 beneficial.
• 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 for high message rates and low-latency workloads.
• Improve existing components for latency, throughput, and CPU and memory efficiency.
• Develop and tune networking, messaging, and I/O layers to reliably handle large data volumes.
• Profile and diagnose performance issues at the application, operating system, and network levels.
• Work with quantitative, trading, and infrastructure teams—or equivalent business and technology teams—to turn requirements into robust technical solutions.
• Write clean, production-quality code with appropriate tests and documentation.
• Take part in code reviews, design discussions, and ongoing improvements to engineering practices.
