The Transaction Processing - Gateways team in Berlin is in charge of building, enhancing and maintaining payment processing products, with PPRO Global processing gateway as the core platform. The team needs to ensure the platform is continuously fully-featured, scalable, reliable, cost-efficient, secure, and auditable while discovering new ways to reduce the integration efforts from customers and reduce the time to enable new payment methods.

• Build and maintain PPRO’s main payment processing engine that is exposed via the PPRO API.
• Own end-to-end products and services from design to rolling out to production.
• Execute with a "you build it, you run it" mindset, potentially participating in an on-call rotation.
• Share your knowledge and build creative solutions while helping your team as well as stakeholder teams to evolve for the best practices.
• Be an integral part of an agile team that collaborates closely and transparently via pair programming, asynchronous communication over ADRs and RFCs, knowledge sharing as well as on-demand brainstorming sessions.
• Use the latest technologies to solve real problems for our customers at a massive scale.

• Results-orientated, collaborative, pragmatic mindset.
• Experience in designing and building scalable products and services.
• Motivation and appetite for problem solving.
• Great skills to break down complex problems into manageable and deliverable pieces.
• Excellent writing and drawing skills and willingness to express your ideas in such forms to provide the best overview possible for any incoming problem.
• Working proficiency in English.

Technical requirements:

In the transaction processing domain, we build and maintain PPRO's primary payment gateway. Therefore, our expectations are high. We expect you to bring knowledge and experience in most of the following technologies:
