Network Engineer jobs in United Kingdom

Software Developer (Research Infrastructure) | Quantitative Trading | £350–500k

How many opportunities will you get to develop a greenfield platform that directly shapes the future of a multi-billion-dollar prop trading business? I'd imagine this is one of few.

Here, you'll develop a proprietary Python-based research platform from scratch for one of the leading Quantitative Traders globally.

The challenge isn’t just performance or raw throughput - though both matter. It’s building a flexible, robust system capable of supporting a wide range of research workflows, each with its own quirks, data dependencies, and computational demands.

You won't just be writing clean, efficient Python, you'll be working directly with researchers to understand their methodology, tooling, and pain points. The system you help design will either accelerate the productivity of some of the smartest minds in quantitative finance - or get in their way.

There’s no single background that guarantees success here, but mastery of Python, a deep understanding of system design, and a collaborative mindset are non-negotiable. While most of the team comes from big-tech, there's space for exceptional buy-siders too.

Here, culture matters. This is a flat, collaborative team with no space for ego. They move fast, build carefully, and share success (and failures) together. If you're looking for a heads-down, siloed role, this isn't the right fit.

If you want to be involved from the beginning - shaping how this platform evolves from scratch - now is the time to reach out.

What they’re looking for:

• 2–10 years of experience in a high-performance, engineering-driven environment
• Advanced Python proficiency
• Experience designing and building complex, data-intensive systems
• Strong Linux fundamentals
• Excellent communication skills and a comfort working closely with non-engineering stakeholders
• Great to have: experience with containerization (e.g., Docker, K8,) and exposure to Golang

If this sounds interesting - or if you're simply curious to learn more - reach out for a conversation.

The team is actively hiring and will move quickly for the right person.
