Core SaaS banking engine development in London utilizing Java microservices, Spring Boot, AWS, GCP, and Kubernetes for global bank clients.

Why youStarling Bank Ltd is an A-rated UK Skilled Worker licensed sponsor, and Engine represents their highest-growth international SaaS product division.

Starling Bank is one of the UK's leading digital challenger banks, and its software arm 'Engine by Starling' licenses its core banking platform to global financial institutions. Starling Bank Ltd holds an active A-rated UK Skilled Worker sponsor license. The team is responsible for architecting multi-tenant, cloud-native banking engines that process millions of real-time transactions with strict reliability guarantees.
