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.

• 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.
