Job Description

  • Build and evolve business-critical payment services using Kotlin, Java and Spring Boot, enabling customers to move money reliably through SEPA while supporting the wider banking platform.
  • 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.

Qualifications

  • Strong experience building backend services with Kotlin or Java and Spring Boot.
  • A solid understanding of Domain-Driven Design and the ability to translate complex business processes into clear software models.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
