Senior Software Engineer, C++ (Market Data)

Flow Traders is seeking a Senior C++ Software Engineer to lead the next-generation architecture of market data and execution platforms powering fully systematic trading. In this role, market data is treated as a source of alpha, where feed handling, order book construction, and deep understanding of exchange microstructure provide competitive advantage.

As a senior individual contributor, you will help set the technical direction for the Core Platform underpinning quantitative research, pricing, strategy development, and execution across hundreds of venues. You'll work in close collaboration with quants and technical traders, applying expertise in modern C++, OS internals, CPU and memory architecture, lock-free concurrency, and low-latency networking to achieve state-of-the-art performance, robustness, and observability.

• Lead development and global rollout of the Core market data platform across multiple focus areas
• Design and implement high-performance components for market data ingestion, normalization, and distribution
• Develop tools and frameworks enabling quants and traders to build, tune, and deploy data-driven systematic pricing and trading strategies
• Own the full lifecycle of components: deploy, monitor, profile, and optimize in production
• Work closely with engineers, quants, and technical traders to refine requirements and iterate on platform design
