Senior Software Engineer, C++ , Core Platform
Flow Traders · Amsterdam
About the role
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 - for us it's a source of alpha, where feed handling, order book construction, and a deep understanding of exchange microstructure are themselves a competitive edge. We're looking for 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 - and drive its global rollout across our Market Data, Quant Research, Pricing, and Strategies groups. 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 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.
