Senior Software Engineer - Payments Platform (Greenfield Project)

Join a major UK-based financial services group at a pivotal moment as they build a brand-new payments platform from the ground up. This is a unique opportunity for a Senior Software Engineer to help shape the future of liquidity and international payment solutions, with real influence on architecture, tooling, and delivery approach.

About the Role

You’ll be joining a feature team within the Payments Platform area, working on a Greenfield application designed to automate and modernise currently manual operational processes. The solution plays a key role in modernising how the business handles international payments, CHAPS transactions, and liquidity management.

This is a chance to take ownership, guide junior engineers, and work closely with stakeholders from engineering, operations, and product. The project is in the early design phase, so decisions around architecture and cloud platforms are still to be made, making this a great opportunity to shape the direction of the build.

Skills required:

• Proven full-stack engineering experience, ideally with Java (Python a plus) and modern front-end development using React.
• Strong understanding of microservices architecture and modern design patterns.
• Experience with cloud-native technologies, Kubernetes, and CI/CD pipelines.
• Previous exposure to payments systems, SWIFT, or liquidity solutions is a strong advantage.
• Comfortable leading discussions, making architectural decisions, and supporting junior developers.

• Apply now to help redefine how one of the UK’s largest financial institutions delivers its payments' capability.
