(Senior) Java Developer (m/f/d)

• Join an internationally successful development team and help shape a secure, highly available platform. 
• We care about clean, maintainable code. Quality and trade-offs are discussed openly, not treated as formality. 
• You’ll work with modern technologies like Java 25, Spring, MySQL, and GitLab CI. 
• Shape solutions alongside product, UX, and your fellow developers – your perspective goes into the design, not just the implementation. 
• Invest in your growth: 10% of your working time is reserved for learning or personal projects.

You… 

• Think in terms of the problem, not just the ticket, you ask why something is being built, not only what. 
• Write code that others can read, change, and trust, and you care about the craft of doing so. 
• Collaborate naturally with teammates and other teams, and communicate clearly in writing and in conversation. 
• Take ownership from problem to production – you see features through, not just to the pull request. 
• Value pragmatism over purity. You can tell the difference between "good enough for now" and "this will hurt us later." 

And you bring hands-on experience with: 

• Java and its ecosystem, with solid fundamentals in testing, version control, CI/CD, and how software runs in production. 
• Some of the tools we use day-to-day (Spring, Maven or Gradle, SQL, GitLab) knowing the rest can be picked up on the job.

• We only offer permanent employment contracts.
• 30 days of vacation per year.
• Working from HQ in Karlsruhe? Our kitchen conjures up a truly excellent, free meal for you every day.
• On December 24th and 31st, we’ll give you an additional day off.
• Work abroad for up to 20 days per year: Working with a sea view? Yes, please!
