Job description

A leading quantitative trading and investment technology firm is establishing a new engineering hub in Amsterdam, with ambitions for it to become a key center of excellence for its European business.

The firm operates globally across liquid financial markets and combines cutting-edge technology, large-scale research, and world-class engineering to tackle some of the most challenging problems in systematic trading. They are now seeking experienced C++ engineers to join a high-performance technology team building and optimizing the ultra-low-latency systems that underpin their trading operations.

The Role

You'll work at the intersection of software, hardware, and networking, helping to design and develop latency-critical systems where every microsecond matters. This is an opportunity to work on the full stack of performance optimization, from highly tuned C++ applications through to operating system, networking, and hardware-level considerations.

Engineers in the team collaborate closely with experts across software engineering, infrastructure, and FPGA development to deliver end-to-end solutions in a highly technical environment.

Responsibilities

• Design, develop, and optimize high-performance C++ systems for trading, market data, and infrastructure workloads
• Analyze and improve latency across CPU, memory, cache, and networking layers
• Build scalable and reliable components for real-time distributed systems
• Work closely with hardware, networking, and FPGA teams to optimize critical data paths
• Profile, benchmark, and troubleshoot performance bottlenecks in production systems
• Contribute to the design of next-generation low-latency architectures

Requirements

• 3+ years of professional experience developing performance-critical software in modern C++ (C++17 or newer)
• Strong understanding of systems programming and low-level software architecture
• Deep knowledge of memory management, CPU architecture, cache behavior, and concurrency
• Experience working in Linux environments with familiarity around kernel tuning and performance profiling
• Understanding of networking fundamentals and system performance under load
• A genuine interest in performance optimization and solving complex engineering challenges
• Low-latency trading, HFT, market‑making, or exchange connectivity
• TCP/UDP networking
• FPGA interaction and hardware acceleration
• Performance profiling and benchmarking tools

What's on Offer

• Opportunity to join a newly established Amsterdam engineering hub at an early stage
• Work alongside some of the strongest engineers in quantitative trading
• Tackle highly complex technical challenges at the intersection of software and hardware
• Competitive compensation package and relocation support
• Collaborative, engineering-driven culture with significant ownership and impact
