SWE - Custom I O

We tackle the most complex problems in quantitative finance, by bringing scientific clarity to financial complexity. From our London HQ, we unite world-class researchers and engineers in an environment that values deep exploration and methodical execution - because the best ideas take time to evolve.  Together we’re building a world-class platform to amplify our teams’ most powerful ideas. As part of our engineering team, you’ll shape the platforms and tools that drive high-impact research - designing systems that scale, accelerate discovery and support innovation across the firm. Take the next step in your career. **The role** This role sits within the Basecamp Technology group, providing specialised engineering capabilities and scalable components to our Research and Trade Technology groups. Join a high-impact team building a greenfield, in-house storage platform to replace a major external vendor dependency. You’ll work on a multi-year programme starting with data orchestration and tiering, and evolving into a custom distributed storage system tailored to large-scale research workloads. This is a great opportunity to shape core infrastructure from first principles, with direct impact on performance, cost, and research capability. Key responsibilities: * Design and build a storage abstraction layer enabling seamless data movement across tiers * Develop tooling for automated dataset tiering and workflow integration * Contribute to the design and implementation of a custom distributed storage platform * Integrate with internal research systems and data platforms * Optimise for performance, scalability, and reliability * Collaborate with researchers to support evolving data needs * Own systems end-to-end, from design through to production **Who are we looking for?** The ideal candidate will have the following experience: * Strong software engineering experience, ideally with Rust * Experience building distributed systems, infrastructure, or data platforms * Solid understanding of systems design, performance, and scalability * Ability to work on complex, low-level technical problems * Experience with storage systems, large-scale data, or high-performance environments is a plus **Why should you apply?** * Highly competitive compensation plus annual discretionary bonus * Lunch provided (via _Just Eat for Business_) and dedicated barista bar * 35 days' annual leave * 9% company pension contributions * Informal dress code and excellent work/life balance * Comprehensive healthcare and life assurance * Cycle-to-work scheme * Monthly company events _G-Research is committed to cultivating and preserving an inclusive work environment.
