L6 C++ Software Engineer

Job Title:

C++ Software Engineer (Level 6) - Low Latency Trading Systems

Location:

Amsterdam, NL (Hybrid)

About Us:

We are a global leader in high-frequency trading, leveraging advanced technology and quantitative research to compete in some of the most challenging markets worldwide. Our engineers build systems where every nanosecond matters, pushing the boundaries of performance and reliability.

Role Overview:

As a Principal C++ Engineer, you will be at the forefront of designing and optimizing ultra-low-latency trading platforms. This is a hands-on leadership role where you will own critical components, mentor other engineers, and collaborate with traders and researchers to deliver next-generation solutions.

Key Responsibilities:

• Architect and lead development of high-performance C++ systems for real-time trading.
• Drive latency reduction initiatives across the entire technology stack.
• Profile, benchmark, and optimize code for sub-microsecond performance.
• Collaborate with hardware engineers to exploit CPU architecture, cache optimization, and kernel bypass techniques.
• Ensure system resilience and fault tolerance under extreme market conditions.
• Mentor and guide junior engineers, setting best practices for performance-critical code.

What We're Looking For:

• 10+ years of experience in C++ development with a focus on low-latency systems.
• Deep expertise in Modern C++ (C++17/20), multithreading, and lock-free programming.
• Strong knowledge of network protocols, kernel bypass (DPDK, RDMA), and hardware-aware optimizations.
• Experience with Linux performance tuning, NUMA, and real-time systems.
• Proven track record of building ultra-low-latency trading platforms or similar mission-critical systems.
• Ability to lead technical projects and mentor engineering teams.
