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. 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'll bring
- 7+ years of post‑graduation professional C++ software development experience.
- Experience building low‑latency market data ingestion, order execution, and algorithmic trading systems.
- 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.
- At Flow Traders, we acknowledge the importance of open and transparent communication whether it be with our employees, our stakeholders, or our local and global communities.
- When it comes to salary, Flow Traders uses reliable market research to create base ranges.
- Where candidates will fall within the range depends on a few different factors including but not limited to level of experience, location, and specific skill set.
- We also consider ourselves one global team, and to demonstrate that, all employees are eligible to share in the company’s success through an annual discretionary variable remuneration allocated based on company, group and individual performance and contribution.
