Principal Software Engineer – Credit Card Product

London, hybrid (2 days a week ideal) or remote working

New Credit Card Product - Leading business lending platform

I'm partnered with one of the UK’s most successful fintech scale-ups who have built a platform helping businesses access more than £15 billion in funding.

They’ve recently launched a new product line which has become the company’s highest-growth area, with its own dedicated leadership and roadmap.

They’re now hiring a Principal Software Engineer to become the technical authority across 8 engineering teams working in the card and credit space. This is a critical hands-on IC role driving architecture, mentoring senior engineers, and setting the engineering direction for one of the most commercially important product areas in the business.

• Be the senior technical authority across 8 product teams focused on credit and card systems
• Lead architectural decisions for a high-volume, low-latency backend platform
• Work closely with senior product, platform and engineering stakeholders to define technical direction
• Mentor Lead and Senior Engineers, driving engineering excellence and fostering a high-performance culture
• Play a key role in the migration from legacy technologies to a fully Python-based modern stack
• Bring domain expertise in cards and credit to a high-growth area with a greenfield mindset

What they’re looking for...

• Strong engineering background with deep experience in backend systems (Python preferred, Ruby/Java/Clojure/Go considered)
• Experience working on card-based products — ideally credit, but debit or prepaid also considered
• Strong architectural and system design skills

What’s in it for you...

• Bonus at approximately 15%-22%
• Annual stock grant (RSU's)
• Dedicated annual learning budget
• Private medical and dental insurance
• Broad range of benefits including enhanced Paternity/Maternity cover
• Hybrid or Remote working – ideally 2 days/week in their London office (no fixed days)
• Be part of a high-ownership role with real scope to shape the success of a growing product
