Du arbeitest eng mit unseren Produktmanagern, Entwicklern und Architekten zusammen, um robuste und skalierbare Backend-Lösungen auf Basis moderner Java-Frameworks – insbesondere Spring Boot – zu entwickeln.

  • Du führst regelmäßige Code-Reviews durch und unterstützt das Team beim Etablieren von Best Practices.
  • Du setzt bewährte Sicherheitsstandards um und beugst gängigen Sicherheitslücken vor.
  • Du arbeitest mit Datenbanken (MySQL, MariaDB, Redis), um effiziente Datenmodelle und Abfragen zu entwickeln.
  • Du nimmst an technischen Planungsrunden teil und bringst dich aktiv in Architekturentscheidungen ein.

Qualifikationen

  • Umfangreiche Berufserfahrung in der Java-Backend-Entwicklung
  • Fundierte Expertise in Spring Boot (oder vergleichbaren modernen Frameworks wie Quarkus oder Micronaut)
  • Sehr gutes Verständnis von objektorientierter Programmierung, Dependency Injection und Design Patterns
  • Erfahrung in der Konzeption und Optimierung von Datenbanken (MySQL, MariaDB, Redis)
  • Sicherer Umgang mit automatisierten Tests (JUnit, Mockito)
  • Vertrautheit mit HTTP-REST-Schnittstellen und API-Dokumentationsformaten (Swagger/OpenAPI)
  • Erfahrung mit agilen Methoden (Kanban, Scrum)
  • Gutes Verständnis von Web-Sicherheitsprinzipien und gängigen Sicherheitslücken

Wünschenswerte Qualifikationen

  • Erfahrung mit Domain-Driven Design (DDD) und Softwarearchitektur
  • Kenntnisse in CI/CD-Prozessen und DevOps-Praktiken
  • Vertrautheit mit Docker und Kubernetes
  • Beiträge zu Open-Source-Projekten oder aktive Teilnahme an der Entwickler-Community
  • Erfahrung mit Message Queues und asynchroner Verarbeitung

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
