## Description (the employer's text)

### About

What you'll do

- Build the features that keep buyers coming back, such as Watch Collection, Wishlist, and the user account.
- Work closely with product management and UX: challenge product ideas, propose simpler solutions, and bring your technical expertise together with their product expertise.
- Design and build backend services and APIs with Java and Spring, implement the frontend changes a feature needs, and keep it all reliable in production.
### What you can expect

- A platform used by millions of watch enthusiasts worldwide, with the reach of an established marketplace and the short decision paths of a small team.
- Open discussions about quality and trade-offs, where good arguments count for more than hierarchy.
- Java 25, Spring, MySQL; Vue.js, Jetpack Compose, and SwiftUI across web, Android, and iOS; GitLab CI; AI tools like Claude Code in our daily workflow.
- 10% of your working time reserved for learning or personal projects.
### What sets you apart

- Think in terms of the problem, not the ticket, and care whether a feature actually makes a difference for buyers.
- Write code that others can read, change, and trust.
- Are most at home in the backend, but don't stop at the API when a feature needs frontend changes.
- Use AI tools like Claude Code every day and review their output as critically as you would a colleague's code. Experience in setting up and improving an agentic coding environment is a plus.
- Enjoy a good debate: you challenge ideas, including ours, and commit once a decision is made.
- Value pragmatism over purity and can tell "good enough for now" from "this will hurt us later."
- Java and its ecosystem, including testing, CI/CD, and how software runs in production, and some of the tools we use (Spring, Maven or Gradle, SQL, GitLab).
- Frontend development on at least one of our platforms: web (Vue.js), Android (Jetpack Compose), or iOS (SwiftUI). You don't need to be a specialist, but you can build and change UI features confidently.
### What we offer

- 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!
### Diversity@Chrono24: We believe in the power of diversity.

At Chrono24, we embrace diversity because we believe it enriches not only our corporate culture but also our success. Be yourself – and let’s achieve great things together!
