Software Engineer - 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
