Senior Software Engineer, C++ , Core Platform

Flow Traders is seeking a Senior C++ Software Engineer to lead the next-generation architecture of the market data and execution platforms that power fully systematic trading. You'll help set the technical direction for the Core Platform that underpins quantitative research, pricing, strategy development, and execution across hundreds of venues, and drive its global rollout across Market Data, Quant Research, Pricing, and Strategies teams. 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 systems toward state-of-the-art performance, robustness, and observability.

What you'll do

• Lead the development and global rollout of the Core market data platform used across multiple focus areas including market data, research engineering, pricing, and strategies
• Design and implement high-performance components for market data ingestion, normalization, distribution, 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 production: deploy, monitor, profile, and optimize your code in a fast-paced, iterative environment
• 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 bring

• A BSc, MSc, or PhD in Computer Science, Mathematics, or a related field
• 7+ years of post-graduation professional C++ software development experience
• Experience building low-latency market data ingestion, order execution, and algorithmic trading systems, preferably in the proprietary trading industry
• Strong knowledge of algorithms and data structures
• Experience in parallel, asynchronous, and multithreaded programming
• A demonstrated ability to write clean, reliable, and highly scalable C++ code
• An interest in extracting maximum performance from available hardware and software, including CPU caches, memory layout, and networking
• The ability to communicate effectively with both technical and non-technical colleagues
