Senior C++ Developer

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.

This role is ideal for an engineer with strong experience in:

• modern C++ (C++17/20)
• high-volume real-time data processing
• high-frequency / low-latency systems
• Linux backend development
• Experience in trading, market data, or other latency-sensitive domains is highly valued

Why this role is interesting:

This is not a typical backend position. You’ll work on a platform where:

• sub-millisecond latency matters
• systems process large volumes of real-time market data
• engineering decisions directly affect speed, reliability, and execution
• the team is preparing for a major migration to 23-hour trading by December 2026

Core stack: C++ (~75%), C# (~20%), Python (~5%)
Architecture: Linux backend, Windows Desktop front end, colocated infrastructure in New Jersey
What you’ll do:

• Build and optimize core components of a C++ trading platform
• Process and distribute high-volume real-time market data
• Improve order management, execution, and risk routing
• Work on systems with high-frequency updates and strict performance requirements
• Profile and optimize latency, throughput, and memory usage
• Support system stability and resolve production issues in a mission-critical environment

What we’re looking for:

• 5+ years of professional C++ experience
• Strong expertise in multithreaded, high-performance systems
• Experience with real-time / high-throughput data processing
• Strong knowledge of Linux, networking, and performance optimization
• Experience with distributed systems
• Good English for professional communication

Strong plus:

• Trading / market data experience
• OMS / EMS / risk systems exposure
• Multicast networking
• C# and/or Python
• U.S. equities knowledge

Why join:

• Work on a real low-latency trading product
• Solve deep engineering challenges in performance and reliability
• Join a strategically important team buildout
• High ownership, strong technical impact
• Fully remote across Ukraine and Europe

Interested?

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