Industry: Fintech Platform

We’re working with a profitable, high-growth UK fintech building a platform used by wealth and advisory firms to manage investment accounts, portfolios and trading workflows.

Following a recent Series C funding round, the company is scaling quickly and continuing to expand the product platform — both in terms of scale and functionality. As a result, they’re growing the engineering team and looking for a Lead Python Engineer to take ownership of a core part of the platform.

The Role

This is a hands-on technical leadership role (50-70% hands-on), leading a small backend pod while remaining closely involved in development. You’ll be responsible for building and evolving core backend systems that support investment workflows, financial data processing and trading-related operations.

What You’ll Be Working On

• Building scalable backend services in Python
• Designing systems that process financial data and investment workflows
• Leading architecture and technical design for new features
• Running a small engineering pod and guiding delivery
• Improving reliability, performance and resilience of core systems
• Mentoring engineers and raising engineering standards across the team

What We're Looking for

• Extensive experience with commercial Python backend development
• Experience building production backend systems
• Experience leading projects or small engineering teams
• Strong understanding of distributed systems or data-heavy platforms
• Comfortable working in a fast-moving scale-up environment

Why apply?

• Work on core financial infrastructure
• Join a profitable company with strong funding and real platform adoption
• Lead a pod while staying deeply hands-on technically
• Help shape a platform that is growing quickly in both scale and capability

Feel free to contact Chris Williams with any questions.
