Your role in the team

  • Develop services across the payment lifecycle, including initiation, validation, execution, status handling, returns, exception management and reconciliation.
  • Design clear domain models, APIs and event-driven workflows connecting customer-facing products with internal systems and external banking partners.
  • Write clean, secure, well-tested and maintainable code, with particular attention to correctness, resilience and traceability when moving money.
  • Develop and operate cloud-native applications on AWS, including containerised services on ECS and event-driven workloads on Lambda.
  • Shape reliable delivery and operations with infrastructure as code, CI/CD pipelines, observability and monitoring.
  • Work in autonomous, cross-functional teams using agile practices, Domain-Driven Design, code reviews, automated testing and continuous delivery.
  • Take ownership from idea to production, delivering measurable value while improving quality, automation, reliability and developer experience.
