Senior Software Engineer – Interfaces

The Purpose:

At PPRO, Senior Software Engineers make some of the most significant decisions for the company.

Think of yourself as an important contributor to the success of your team, with a significant impact on the team’s product, but also on its culture and spirit.

The Transaction Processing - Interfaces team in Munich is charged with defining and executing a bold, global vision and strategy for Interfaces and configurations at PPRO.

This team drives the design and architecture of frontend and backend solutions in a high‑scale, dynamic environment. Your work will help establish a foundation to enable the efficient creation of frontend solutions for teams across the company as well as enabling them to do distributed configuration management.

What you’ll do:

• Build and maintain the backend services and modules that power PPRO’s interfaces and platforms, including the main payment processing engine exposed via our API
• Take full end‑to‑end ownership of your work, driving products and services from the design phase all the way to rolling them out in production
• Execute with a "you build it, you run it" mindset, identifying technical risks and participating in an on‑call rotation to ensure our systems remain healthy and reliable
• Act as an integral part of an agile team that values transparency, collaborating closely through pair programming, asynchronous communication (using ADRs and RFCs), and knowledge sharing to help stakeholders evolve toward best practices
• Use the latest technologies to solve real, complex problems for our customers at a massive scale

What we look for in you:

• A results‑oriented, collaborative, and pragmatic mindset with a hunger for problem‑solving and continuous improvement
• Excellent writing and drawing skills. As a Senior Engineer, you need to be able to break down complex problems into manageable pieces and articulate the tradeoffs of your technical decisions to a broad audience
• Proven experience designing and building scalable products and services, particularly within a cloud‑native environment
• Working proficiency in English

Technical Requirements

• We expect the candidates to bring deep knowledge and experience in the following areas:
• Extensive experience with Java 21 and Spring Boot 3
• Hands‑on experience with AWS components (specifically EKS, DynamoDB, Kinesis, and OpenSearch) and Infrastructure‑as‑Code tools like Terraform
• A strong understanding of event‑driven microservice architecture, Docker, and Kubernetes
• Context is key: While this is a backend role, you will be working in a team focused on Micro‑frontend architecture
• Experience or a track record of building architectures that support multiple modules and widgets is highly relevant
• Experience using observability tools like Datadog to monitor the health of your services

Even better if you have:

• A background in the payments industry.
• Hands‑on experience with AI as a software engineer
