Job description

A leading global quantitative trading firm is seeking an experienced C++ Software Engineer to join its world-class technology team!

In this role, you’ll design and build highly performant, fault-tolerant systems that power trading across global financial markets. The firm’s distributed architecture operates on the Pareto frontier of latency and throughput, offering a rare opportunity to apply and deepen your expertise in C++, operating system internals, CPU architecture, and networking hardware and protocols.

You’ll collaborate closely with researchers, traders, and hardware specialists to deliver solutions where every microsecond counts. With a bottom-up approach to innovation and a highly collaborative culture, engineers are empowered to take ownership, drive meaningful projects, and see the direct impact of their work every day.

This is an opportunity to tackle complex technical challenges in a fast-paced, highly competitive industry, alongside some of the brightest minds in quantitative finance and systems engineering.

What You’ll Work On:

• Develop and optimize infrastructure for market data ingestion, order entry, and execution logic across a broad range of asset classes, including options, equities, futures, crypto, and fixed income.
• Design and implement fault-tolerant, ultra-low-latency systems for live trading, including WAN data encoding/prioritization and resilient recovery from hardware failures.
• Profile, benchmark, and enhance performance-critical production code with a focus on both throughput and latency.
• Build and maintain core infrastructure supporting client-facing wholesale and SDP platforms, distributed network filesystems, and scalable research workflows.
• Develop software that interfaces with specialized trading hardware, including FPGAs and ASICs.

Qualifications:

• 3+ years of professional software engineering experience
• Bachelor’s degree in Computer Science or a related technical field
• Exceptional system design, debugging, and problem-solving skills
• Strong, hands-on C++ expertise (advanced proficiency required; daily use preferred)
