The Mission

We're looking for a backend engineer with business knowledge to build and evolve our EBICS payment processing system. You'll work on mission-critical banking infrastructure where understanding why payments work the way they do matters as much as knowing how to code them. If you're curious about business domains, comfortable with payments terminology, and want to grow from coder into a system thinker, this is the role.

• Learn Axway integration for secure message transport in banking;
• Collaborate with ops and security teams on reliability and compliance;
• Debug production issues in a financial system where availability is non-negotiable;
• Participate in code reviews and architecture discussions.

Core Responsibilities

• Write clean, testable backend code in Python/Bash/Golang;
• Implement business logic correctly (understand payment terminology, not just APIs);
• Deploy and monitor your own services;
• Integrate with payment protocols (EBICS, SWIFT, SEPA ISO 20022);
• Maintain secure, compliant code; understand why security matters in banking;
• Document your decisions and teach others how systems work.

Business Mindset

• Genuine curiosity about how banking and payments work;
• Proactive attitude;
• Willingness to learn payment terminology;
