Senior Software Engineer, C++ (Market Data)

About the role

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. Market data is treated as a source of alpha, where feed handling, order‑book construction and deep exchange micro‑structure knowledge provide a competitive edge.

Key responsibilities

• 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 components in a fast‑paced, iterative environment: deploy, monitor, profile and optimise code in production.
• Collaborate closely with focus‑group engineers, quants and technical traders to refine requirements, collect feedback and iterate on platform design and implementation.

Required profile

• BSc, MSc or PhD in Computer Science, Mathematics or a related field.
• 5+ years of professional C++ software development experience after graduation.
• Experience building low‑latency market data ingestion, order execution and algorithmic trading systems, preferably in proprietary trading.
• Strong knowledge of one or more APAC markets and 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 hardware and software (CPU caches, memory layout, networking, etc.).
