Java Software Engineer in Germany

Java Software Engineer MUST have Quarkus and Dapr experience

Role Overview
We are looking for a Software Engineer with hands-on experience in building microservices and 12-Factor, cloud-native applications using Java, Quarkus and Dapr. You will design, implement, and operate distributed services running on containerized infrastructure with fully automated CI/CD pipelines.
This is a must-have Quarkus + Dapr role: you will actively use both frameworks daily to build resilient, observable, and event-driven services.
Key Responsibilities
* Microservices design & implementation
o Design and develop backend microservices using Java and Quarkus.
o Apply 12-Factor App principles (config externalization, stateless processes, disposability, logs, etc.).
o Implement synchronous and asynchronous communication patterns (REST/gRPC, pub/sub, events).
* Dapr-based cloud-native services
o Use Dapr sidecars and building blocks (service invocation, pub/sub, bindings, state stores, secrets, workflows) to build loosely coupled services.
o Define and maintain Dapr component configurations for various backends (message brokers, state stores, etc.).
o Implement resilience patterns (retries, timeouts, circuit breakers, idempotency) leveraging Dapr and Quarkus.
* CI/CD & DevOps collaboration
o Work with CI/CD pipelines (e.g. GitLab CI, GitHub Actions, Azure DevOps, Jenkins) for build, test, security scanning, and deployment.
o Ensure high test coverage through unit, integration and contract tests integrated into the pipeline.
o Deploy and operate services on container orchestration platforms such as Kubernetes.
* Quality, security & observability
o Write clean, maintainable, testable code following best practices and design patterns.
o Implement observability: structured logging, metrics and distributed tracing (e.g. via OpenTelemetry through Quarkus/Dapr).
o Collaborate on secure service design (OAuth2/OIDC, JWT, secrets management, TLS).
* Collaboration & lifecycle ownership
o Work in cross-functional agile teams with product owners, architects and other engineers.
o Participate in code reviews, design sessions, and troubleshooting of production issues.
o Own services end-to-end from design through implementation to monitoring and continuous improvement.
