Job description

Flow Traders 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—our focus is on extracting alpha from feed handling, order book construction, and a deep understanding of exchange microstructure. We're seeking 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 help set the technical direction for the Core Platform that underpins quantitative research, pricing, strategy development, and execution across hundreds of venues. You will drive its global rollout across our Market Data, Quant Research, Pricing, and Strategies groups, working 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 our systems toward state‑of‑the‑art performance, robustness, and observability.

What you will do:

• Lead the development and global rollout of our Core market data platform used across multiple focus areas (Market data, Research engineering, Pricing, Strategies).
• 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.
• 7+ 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 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.
