Our main goal is to empower our product teams to deliver software products more quickly, reliably, and efficiently.

Your Profile – authentic & open-minded

• Long-term and profound professional experience in developing modern, cloud-native microservices in Java, with hands‑on expertise in Spring Boot
• Experience with or a strong desire to master Go for cloud-native development, especially in building Kubernetes operators and automation tools

• Experience in CI/CD concepts and practical skills in configuring and using pipelines, preferably with GitLab CI
• Solid understanding of at least one major cloud provider (AWS or Azure) and containerization
