Senior Fullstack Entwickler (m/w/d) — Behörden & öffentlicher Sektor

Wer wir sind

Rockstardevelopers, gegründet 2015 in Mannheim, weitere Büros in Stuttgart und München. Wir sind ein Software-Entwickler mit Erfahrung aus hunderten von individuellen Projekten für Enterprise- und Mittelstands-Kunden.

Kurze Wege, ehrliches Feedback, keine politischen Spielchen. Keine Hierarchie-Ebenen zwischen dir und den Leuten, die Entscheidungen treffen.

Deine Aufgaben

Du arbeitest in Projekten für öffentliche Auftraggeber — etwa Bundesagentur für Arbeit, ITZ Bund oder Bundesdruckerei — eingebettet in deren Teams, mit voller Verantwortung für deinen Bereich.

• Fullstack-Entwicklung in regulierten Enterprise-Umgebungen
• Architektur mitgestalten, nicht nur umsetzen
• Code generieren, reviewen und refactoren mit Claude Code, Copilot oder Cursor
• Code Reviews und technisches Mentoring im Team
• Abstimmung mit Product Ownern, UX und DevOps

Was du mitbringst

Senior-Level. Unsere Kunden brauchen Leute, die ab Tag eins liefern und eigenständig arbeiten.

Fester Backend-Kern (das erwarten wir):

• Java (17+) und Spring Boot
• REST-Schnittstellen, relationale Datenbanken (PostgreSQL, MariaDB, Oracle o. ä.)
• Docker und Kubernetes
• CI/CD (Jenkins, GitHub Actions), Git, agiles Arbeiten

Frontend (eines davon sicher, beide ein Plus):

• React / Next.js oder Angular, jeweils mit TypeScript

Im Behördenumfeld zusätzlich relevant:

• Barrierefreiheit (BITV 2.0 / WCAG AA)
• DevSecOps / Security by Design
• Erfahrung in regulierten Umfeldern oder im öffentlichen Sektor

Von Vorteil (kein Muss):

• Apache Kafka / asynchrone Kommunikation
• Microservices, Domain Driven Design, JPA/Hibernate
• Monitoring (Grafana, Prometheus), Object-Storage (S3)
• Tests (JUnit, Jest, Playwright, Cypress)

Du musst nicht alles können. Wichtig ist, dass du auf beiden Seiten sicher bist und dich schnell in neue Stacks reinfindest.

AI-Erfahrung ist bei uns keine nette Zusatzqualifikation. Claude Code, Copilot, Cursor: Damit musst du produktiv arbeiten können. Nicht weil wir hip sein wollen, sondern weil unsere Kunden das erwarten und wir auch so arbeiten. Wenn du AI-Tools für einen Hype hältst und lieber alles selbst tippst: falsche Firma.

Was wir bieten

• Homeoffice, Büro oder Mix, du entscheidest
• MacBook (ausser der Kunde stellt eigene Hardware)
• Verschiedene Kunden, verschiedene Projekte
• Die Gründer sind deine direkten Ansprechpartner
• Internes Upskilling: Wir investieren in deine AI-Skills (EXO 3.0, Agent-Passport, Zertifizierungen)
