Job Description

• Join a leading high-frequency trading firm at the forefront of low-latency technology
• Design, build, and optimise high-performance C++ systems on Linux
• Collaborate closely with traders and researchers on real-time trading infrastructure
• Work in a hands-on, engineering-driven culture where technical excellence matters

The Role

You’ll develop and enhance the systems that power one of the most sophisticated high-frequency trading environments in the market. The role involves end-to-end ownership of software components, from architecture and design through to implementation and optimization. You’ll be writing modern C++ that runs at scale and with extremely low latency, focusing on efficiency, reliability and throughput.

Your work will involve multithreaded programming, concurrency control, memory management and parallelism, all within a Linux environment. You’ll collaborate closely with experienced engineers and traders, contributing to systems that handle real-time data and execute strategies in microseconds.

This is an in-office position based in downtown Chicago, offering a highly collaborative and intellectually stimulating environment for engineers who thrive in fast-paced, performance-critical systems.

Key Skills and Experience Required

• 2–4 years of post-graduation professional software engineering experience
• Strong proficiency in C++ as your primary programming language, with solid understanding of modern standards (C++14 or newer)
• Strong knowledge of multithreading and memory management, with additional exposure to concurrency models or parallel computing a plus
• Strong computer science fundamentals including algorithms, data structures, and performance analysis
• Experience developing in Linux/Unix environments
• Bachelor’s degree in Computer Science or related field from a leading university
• Familiarity with real-time systems, networking, or low-latency trading infrastructure is a plus

Why Join

• Work on cutting-edge high-frequency trading systems where performance and precision are paramount
• Learn directly from senior technologists and traders in a flat, merit-driven structure
• Competitive compensation (base + discretionary bonus)
• Excellent benefits including medical, dental, vision, and 401(k)
• Daily breakfast and lunch, fully stocked kitchen and modern workspace
• Education reimbursement, charity matching, and regular social events

If you’re a C++ engineer passionate about performance and optimisation, and want to work where your code directly impacts trading results in real time, we’d love to hear from you.
