Senior C++ Developer (with Market Data experience)

In this role you will design and build high performance, low latency C++ services processing large real-time data volumes. You’ll optimize across algorithms, networking, and OS layers to achieve microsecond-scale throughput gains. You collaborate with quantitative, trading, and infrastructure teams to translate requirements into robust solutions, while delivering production-quality, tested code. This position lets you shape high-speed systems in a fast-paced, engineering-driven environment with a clear focus on performance impact.

• 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 application, OS, and network levels
• Collaborate with quantitative, trading, and infrastructure 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

• 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
• 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

• strong collaboration
• problem-solving
