Lead Software Engineer

Lead Software Engineer — Python / AWS

London Victoria | Hybrid

Up to £140,000 base

I’m working with a fast-growing fintech/data business building a specialist technology platform for the global credit markets.

Their platform combines large-scale financial datasets, advanced analytics and Generative AI to help some of the world’s leading investment firms analyse complex financial information and make faster, better-informed decisions.

The technology processes hundreds of thousands of official financial documents and structures data across thousands of bond and loan issuers globally , creating some genuinely interesting engineering challenges around scale, performance and data.

They’re now looking for a Lead Software Engineer to take significant technical ownership across the platform.

What they’re looking for:

• Expert-level Python
• Deep AWS experience
• Strong architecture & system design skills
• APIs, microservices & distributed systems
• PostgreSQL / DynamoDB
• Experience leading major technical projects
• Mentoring engineers & raising engineering standards
• Someone who still wants to be genuinely hands-on

This is a technical leadership role rather than a move into pure management — you’ll have real influence over architecture and engineering direction while remaining close to the code.

Interested? Drop me a message and I’ll share more details.
