Job description

Flow Traders Hong Kong is looking for a Senior C++ Software Engineer to lead the next-generation architecture of the market data and execution platforms that power our fully systematic trading. We don't treat market data as plumbing - for us it's a source of alpha, where feed handling, order book construction, and a deep understanding of exchange microstructure are themselves a competitive edge. We're looking for a senior individual contributor who has lived this philosophy in a proprietary or systematic trading environment and can squeeze every nanosecond out of the path from wire to strategy.

As a senior individual contributor, you'll be working on the Core Platform that underpins quantitative research, pricing, strategy development, and execution across hundreds of venues. You'll work in a tight, iterative loop with quants and technical traders, applying deep expertise in modern C++, OS internals, CPU and memory architecture, lock-free concurrency, and low-latency networking to push our systems toward state-of-the-art performance, robustness, and observability.

What you will do:

• Design and implement high-performance components for market data ingestion, normalization, and distribution, as well as its usage for order execution and strategy infrastructure.
• Develop tools and frameworks that enable quants and technical traders to build, tune, and deploy data-driven systematic pricing and trading strategies.
• Own the full lifecycle of your components in a fast-paced, iterative environment: deploy, monitor, profile, and optimize your code in production.
• Work closely with focus group engineers, quants, and technical traders to refine requirements, collect feedback, and iterate on the platform's design and implementation.

What you need to succeed:

• BSc, MSc, or PhD in Computer Science, Mathematics, or a related field.
• 5+ years of post-graduation professional C++ software development experience.
• Experience building low-latency market data ingestion, order execution, and algorithmic trading systems (proprietary trading industry preferred).
• Strong knowledge in one or more APAC markets.
• Strong knowledge of algorithms and data structures.
• Experience in parallel, asynchronous, and multithreaded programming.
• Demonstrated ability to write clean, reliable, and highly scalable C++ code.
• Interest in extracting maximum performance from available hardware and software (CPU caches, memory layout, networking, etc.).
• Ability to communicate effectively with both technical and non-technical colleagues.
