Job Description:

Our client—a world-leading, elite tech-driven trading firm—is assembling a world-class R&D team in London to tackle one of the most demanding engineering challenges on the planet: building systems that operate at exabyte scale with nanosecond precision.

This is an opportunity to work alongside some of the most talented minds in low-latency systems and infrastructure globally — engineers and researchers who are constantly pushing the boundaries of distributed computing, ultra-efficient networking, and high-performance architecture. You'll collaborate in an environment where deep technical expertise, rapid iteration, and precision engineering are not just valued but essential to success.

What You’ll Work On

• Architect and optimise software at the intersection of speed, scale, and storage.
• Bring next-gen supercomputing and high-performance networking online—ground-up, in a brand-new data centre.
• Solve real-world systems problems where every microsecond counts, and every line of code impacts performance.
• Partner with elite researchers, infrastructure specialists, and systems engineers to push beyond conventional limits.
• Co-design hybrid hardware/software systems to accelerate real-time computation at global scale.

What They’re Looking For

• 2-12 years of experience in low-level C++, with a strong understanding of performance-critical environments.
• Hands-on experience working at exabyte scale or within high-throughput infrastructure (Big Tech, HPC, or next-gen infra teams).
• Deep knowledge of computer architecture, networking, and storage systems.
• Exposure to kernel-level tuning, network stack optimisation, or low-latency distributed systems is a significant advantage.
• A passion for systems design, optimisation, and building high-performance tooling from the ground up.

If you're excited by the idea of building architectures that push the boundaries of speed, scale, and precision—we’d love to speak with you.
