C++ Software Engineer — Chicago, IL

Our client a leading quantitative trading firm that is continuing to invest heavily in its engineering organization, specifically across its low-latency trading infrastructure.

This team is focused on building and optimizing the core systems that power real-time trading across global markets, with a strong emphasis on performance, scalability, and reliability. Engineers work closely with traders and researchers to develop highly efficient, fault-tolerant systems that operate at significant scale, where even small improvements in latency or throughput can have meaningful impact.

What you’ll do:

• Design and optimize low-latency infrastructure for market data and order execution

• Build fault-tolerant, real-time systems operating at scale

• Profile and improve performance across latency-critical code paths

• Work closely with traders and researchers on production systems

Looking for:

• Strong experience with modern C++ in performance-sensitive environments

• Solid systems fundamentals (Linux, networking, CPU/memory)

• Experience with low-latency or distributed systems is a plus

• High ownership and strong problem-solving ability
