Overview
We're partnering with one of the world's most successful proprietary trading firms to hire exceptional C++ Software Engineers. This is a rare opportunity to work at the cutting edge of technology where software quality directly drives trading performance and P&L. Our client operates in an ultra-low latency, high-stakes environment and is known for combining elite engineering talent, academic rigour, and significant financial backing. They build almost everything in-house and treat engineering as a core competitive advantage.

The Role
As a C++ Software Engineer, you'll be designing and building high-performance, mission-critical systems that operate at massive scale and microsecond latency. You'll work closely with traders, researchers, and other engineers to solve complex, real-world problems where the impact of your work is immediate and measurable. This is not a maintenance role. You'll be owning core systems, shaping architecture, and pushing modern C++ to its limits.

Key responsibilities include

• Designing and developing high-performance C++ systems for trading, pricing, and market data

• Writing low-latency, highly reliable code in a Linux environment

• Optimising performance across CPU, memory, and network layers

• Collaborating closely with quantitative researchers and traders

• Taking ownership of systems from design through to production

Requirements

• Strong professional experience in modern C++ (C++17/20+)

• Deep understanding of performance, concurrency, and systems-level programming

• Experience building complex, high-throughput, low-latency applications

• Strong computer science fundamentals (data structures, algorithms, OS concepts)

• A mindset that values clean design, code quality, and continuous improvement

• Experience in trading or finance is not required - many successful hires come from big tech, systems engineering, gaming, or other performance-critical domains.
