Quantitative Developer – HFT (C++) | Ultra-Low-Latency Trading | High-Performance Systems

We are looking for an experienced C++ engineer to join a high-performance trading team focused on building ultra-low-latency systems that operate at global scale. This is a unique opportunity to work on cutting-edge technology where every nanosecond counts.

The Role

As part of the HFT team, you will:

  • Design, develop, and optimize latency-critical C++ systems for trading, market data, and infrastructure.
  • Work on end-to-end ultra-low-latency architectures, including kernel-level tuning, network optimization, and highly efficient system components.
  • Collaborate with FPGA engineers and hardware teams to integrate hardware and software pathways.
  • Profile and fine-tune performance across CPU, cache, and memory layers, ensuring maximum efficiency.
  • Contribute to the evolution of a high-throughput, front-office tech stack.

What We're Looking For

  • 5+ years of experience in performance-critical C++ (C++17 or newer).
  • Strong expertise in systems programming, memory management, and CPU architectures.
  • Deep knowledge of Linux internals, kernel parameters, and low-level profiling.
  • Passion for high-performance computing, networking, and hardware-software optimization.
  • Experience in systematic trading, HFT, or quantitative environments is a plus.
  • Proven ability to architect, optimize, and scale ultra-low-latency systems.

Why This Opportunity Is Exceptional

  • Work in a front-office, revenue-driving engineering environment.
  • Build and optimize state-of-the-art HFT systems across software, FPGA, and infrastructure.
  • Join a culture that values innovation, autonomy, and technical excellence.
  • Direct impact on strategy performance and technology evolution.
  • Opportunities to work in global offices.

If you're a C++ engineer excited by ultra-low-latency systems, HFT, and high-performance software design, this is a rare opportunity to make a tangible impact on a top-tier trading desk.
