Senior Software Engineer, C++ (Market Data)

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 its fully systematic trading. Market data is treated as a source of alpha, where feed handling, order book construction, and a deep understanding of exchange microstructure are themselves a competitive edge.

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

• 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: 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.
