As an Internet Service Provider with approximately 10 million managed domains, InterNetX is one of the top providers in the market. The heart of domain management is AutoDNS, supported by a distributed landscape of microservices, interfaces to registries, and specialized business systems operating in a 24/7 high-availability environment.

  • Write unit and integration tests, review merge requests, and help shape CI/CD pipelines via GitLab and Kubernetes.
  • Analyze errors using logs and databases and sustainably resolve root causes.
  • Contribute to functional and technical enhancements (e.g., new regulatory requirements, billing, monitoring, and platform stability).
  • Actively use and shape modern AI tools in daily workflows (e.g., AI coding assistants for refactoring, testing, code reviews, and custom AI agents).

Qualifications

  • Currently enrolled in a degree program related to computer science (e.g., Computer Science, Business Informatics, Media Informatics) with the ability to work alongside your studies.
  • Backend experience with Java and Spring / Spring Boot, confident handling of relational databases, and basic knowledge of REST/web services.

Working Hours: Flexible working hours according to the IONOS standard for working students, adapted to your lecture and examination schedules.
