We are looking for an experienced Backend Developer to join a team responsible for building and maintaining systems that handle reconciliation, financial management, and high-volume transaction flows. In this role, you will work on scalable backend and data-driven systems that ensure accurate payment flows, reporting, and regulatory compliance—while contributing to the modernization of existing platforms and the development of new features related to payment fees.

• Develop modular platform capabilities that improve automation and reduce operational dependencies
• Modernize existing financial systems and contribute to new feature development
• Collaborate closely with product, engineering, and finance teams to translate business processes into technical solutions
• Support cloud-native development and deployment, primarily in Google Cloud Platform (GCP)
• Ensure high standards of code quality, testing, documentation, and long-term maintainability

Qualifications

You bring:

• A T-shaped profile: deep backend or data engineering expertise, with the ability to work across both areas
• Experience with large-scale transactional or financial data flows (e.g., Spark, Flink, Beam)
• Strong backend engineering skills, ideally in Java
• Good understanding of data structures, algorithms, system design and distributed systems
• Experience with cloud-native development, preferably GCP
• A thoughtful approach to architecture and system reliability
• Strong communication skills—you explain ideas clearly and ask the right questions
• A collaborative mindset and ability to work cross-functionally with product and finance
• Comfort working in fast-paced and evolving requirements
• A user-centered mindset when designing platform features
• High standards for code quality, testing, and documentation
• Curiosity, independence, and a drive to continuously improve systems and ways of working

If you're passionate about building robust financial systems, enjoy solving complex data and backend challenges, and want to work in a highly collaborative environment, we’d love to hear from you.
