Junior Software Engineer (m/w/d) — KI-gestützte Entwicklung
data nation GmbH
Standort: Alstertwiete 3, 20099 Hamburg
Über uns:
data nation bringt frischen Wind in die Fitnessbranche durch innovative Digitalisierungs- und Automatisierungsansätze. Unser Ziel ist es, durch kreative Lösungen messbare Erfolge zu erzielen und Standards neu zu definieren. Seit unserer Gründung im Jahr 2021 durch Bruno To-Vinh sind Flexibilität, Offenheit, Kundenfokus, Integrität und Verantwortung die Säulen unserer Unternehmenskultur.
Mit Gymcubator haben wir unser eigenes Produkt entwickelt: eine KI-Plattform für Fitnessstudios, die mit Mitgliedern über WhatsApp und E-Mail kommuniziert, Buchungen und Anfragen verwaltet und Studio-Teams im Alltag unterstützt. Dutzende Studios nutzen das System bereits täglich in Production – und genau hier kommst du ins Spiel: Für die Weiterentwicklung von Gymcubator suchen wir Verstärkung.
Deine Rolle:
Du startest dort, wo man ein Produkt wirklich kennenlernt: beim Onboarding neuer Kunden, im Production Support und beim Beheben von Fehlern. Du arbeitest direkt mit dem Gründer und wächst Schritt für Schritt in eine vollwertige Entwicklerrolle hinein.
Wir setzen KI-Agenten in allen Phasen der Entwicklung ein. Du lernst dabei nicht nur, mit KI schnell Code zu schreiben — du verstehst am Ende wirklich, wie verteilte Systeme in Production gebaut und betrieben werden: moderne Architekturen, Cloud, CI/CD und agentische Systeme.
Deine Aufgaben:
Neue Fitnessstudios onboarden: Einrichtung, Konfiguration, Integrationen
Wiederkehrende Aufgaben im Onboarding automatisieren und den Prozess Schritt für Schritt skalierbar machen
Production Support: Probleme mit Code, Logs und Daten untersuchen und beheben
Bugfixes und kleinere Features umsetzen, testen und releasen
Mitarbeit an Cloud-Infrastruktur und CI/CD-Pipeline: Deployments, Kubernetes, Monitoring
Lernen, KI-Agenten zu steuern und generierten Code kritisch zu prüfen
Mit wachsender Erfahrung: eigenständige Entwicklung von Features
Was wir bieten:
Mentoring direkt durch den Gründer und praxisnahe Ausbildung in KI-gestützter Entwicklung
Ein echtes Verständnis dafür, wie verteilte Production-Systeme mit zahlenden Kunden gebaut und betrieben werden: moderne Architekturen, Cloud, CI/CD und agentische Systeme
Klarer Wachstumspfad vom Support in die Produktentwicklung
Vollzeitstelle in Deutschland

Wen wir suchen
Absolvent:in (Bachelor/Master in Informatik o. ä.) oder vergleichbare Ausbildung mit starkem Portfolio
Solide Programmiergrundlagen; Uni-, Praktikums- oder private Projekte zählen

Unser Stack: Python, FastAPI, PostgreSQL, RabbitMQ, LangGraph, React, TypeScript, Twilio, Kubernetes — Vorerfahrung damit ist nicht erforderlich.
