Senior C++ Developer – US Equities Trading Platform

About the project:
We’re looking for a Senior C++ Developer to join a team building a high-performance electronic trading platform for the U.S. equities market. The platform runs in a low-latency environment, processing large volumes of real-time market data, where speed is critical, and responses are measured in sub-millisecond latency.

Product context:

• C++ ~75% — core engine
• C# ~20%
• Python ~5%
• Linux backend
• Windows Desktop front-end

The platform is currently entering an important scaling phase, driven by a major transition to 23-hour trading mode. This migration is the team’s main priority, alongside maintaining platform stability. The role will involve significant work with legacy code and performance optimization in modern C++

What we’re looking for:

Must-have

• Strong hands-on experience with modern C++ (17/20)
• Commercial experience in low-latency and high-performance systems
• Solid hands-on background in multithreading/concurrency
• Deep understanding of Linux production environments
• Experience working with high-throughput or real-time systems
• Strong understanding of memory management, performance optimization, and network-level tuning

Nice-to-have

• Trading experience is a strong plus, but we are also open to candidates from telecom, gaming, adtech, or other latency-sensitive domains
• Experience working with long-lived legacy systems
• Exposure to C# and/or Python

What you’ll work on:

• Low-latency C++ systems
• High-volume real-time market data processing
• Order management, execution, and risk routing logic
• Aggregation of multiple backend streams into a unified C++ API layer
• Ongoing optimization of latency, throughput, memory usage, and concurrency 

Interested?

If you’re strong in C++, real-time systems, and high-volume processing, we’d love to hear from you
