R&D Software Engineer – Exabyte Storage, Supercomputing

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.
