Infrastructure Software Developer (Python) - Quant Trading Firm

Infrastructure Software Developer (Python) – Trading Firm – London – £140,000 + generous bonus

I'm working with a London-based trading firm that's investing heavily in how its infrastructure is built, and they're hiring a Python developer to write the software that runs it.

• Established, technology-driven trading business
• Small, collaborative engineering team
• Real appetite to treat infrastructure as a software problem

This is a development role first and foremost. You'll sit within the infrastructure team, but your day-to-day will be designing, writing and maintaining the code and internal tools that replace manual work across the estate.

What you'll be working on:

• Building and owning internal infrastructure software and tooling in Python
• Designing infrastructure-as-code frameworks used across the estate
• Writing automation for deployment, patching and configuration
• Developing tooling to improve observability and reliability

What they're looking for:

• Strong, current professional Python, with good software engineering habits (testing, code review, version control, clean design)
• Deep hands-on Linux knowledge
• A track record of building software that automates infrastructure at scale
• Solid networking and security fundamentals
• Clear views on how modern infrastructure should be engineered

What's on offer:

• £140,000 + discretionary bonus
• Genuine ownership of the codebase and influence from day one
• Strong benefits package
• No finance or trading experience required

If you're a software developer who enjoys working close to infrastructure, or an Infrastructure, Platform or DevOps engineer who spends most of your time writing code, whether at a trading firm, Big Tech or any large-scale environment, this is a role worth a conversation.
