We are looking for two Backend Software Engineers (Junior to Middle level) to join a cross-functional squad on the Payments Platform. This is a hands-on execution role: designing, building, testing and operating payment services with clean, maintainable Java code, applying SOLID principles and design patterns, and handling sensitive financial data securely. The engineer works closely with business experts, UX/UI designers and the infrastructure/delivery teams, owning the quality and reliability of what they ship in production.
The client is building its new Payments Platform: a modular, cloud-native backend that connects customer experience, business and technology across every market in the region. The platform drives conversion (frictionless and one-click checkout, local payment methods and currencies, intelligent retry of failed authorizations), operational efficiency (smart routing of each transaction to the processor with the best success/cost ratio, automated reconciliation and chargeback handling) and new revenue models (subscriptions, recurring payments, BNPL, and a loyalty wallet enabling hybrid miles + money payments).

Develop and maintain backend services with clean, testable, and maintainable code
Apply SOLID principles and established design patterns in software development
Implement unit, integration,



and contract tests to support software quality
Apply secure coding practices for API security and safe handling of payment and customer data
Collaborate with infrastructure and delivery teams on CI/CD pipelines
Deploy and operate services in a cloud environment with attention to scalability, security, and resilience
Monitor production performance and resolve incidents proactively

2+ years of professional backend development experience with Java
Hands on experience with Spring Boot building production services
Solid understanding of SOLID principles and common design patterns
