IntroYour Back-End Code Matters

Do you enjoy developing code for dynamic modern web applications? Are you an expert on data structures and algorithms? Then we're looking for you.

You'll work in a self-organized, cross-functional, and agile team. You'll get rewarded with plenty of company perks, an international environment, state-of the-art technologies as well as development tools, and a deep dive into the Atlassian ecosystem.

Your Future Role
  • Develop and implement new features and improvements for our apps, incl. analyzing feature feasibility, creating technical feature specs and much more.
  • Take care of refactoring and maintaining the code base of our apps.
  • Write and maintain automated tests.
  • Empower your colleagues with your technical knowledge, e.g. by mentoring junior developers and sharing your knowledge in internal talks.
  • Provide input and review user documentation from a technical point of view.
  • Create release artefacts and cloud deployments for the Atlassian Marketplace.
  • Explore technologies and tools like AWS, Bamboo, Bitbucket, Docker, Git, IntelliJ, Java, , Spring, and many more.
Your Background
  • Experience in building and maintaining back-end code for dynamic modern web applications – additionally, front-end experience will help you quickly onboard in our cross-functional team.
  • Passion for clean, portable, and well-documented code, thereby ensuring fast processes.
  • Excellent understanding of server-side Java – knowledge of Java 21, Spring Boot and virtual threads is a plus.
  • Hands-on experience with Maven, Git, and designing REST APIs – these experiences build the basis for your daily work.
  • Basic understanding of client-side JavaScript – we use technologies like React, TypeScript, and Redux.
  • Ideally, a degree in applied Computer Science, Software Engineering, Information Technology or similar – if not, we'd still love to receive your application.
