Datenschutz und IT-Security sind dabei keine Nachgedanken, sondern von Anfang an Teil der Architektur. Wir wollen in diesem Bereich Maßstäbe setzen, nicht nur Mindestanforderungen erfüllen.

Da wir auch das Frontend inhouse entwickeln, bringst Du Deine Erfahrung in direktem Austausch mit ein und gestaltest so nicht nur die technische Infrastruktur, sondern das gesamte Produkt mit.

  • Performance-Optimierung unserer Datenbanken und Backend-Dienste für eine wachsende Zahl angebundener Anlagen

  • Anleitung und Betreuung von Trainees

Qualifikation

  • Mehrjährige Erfahrung als Backend-Entwickler mit nachweisbarem Track Record im Betrieb und der Skalierung produktiver Systeme

  • Fundierte Kenntnisse in Linux-Server-/Container- Administration und CI/CD-Pipelines

  • Starkes Bewusstsein für IT-Security und Datenschutz.

Nicht nur als Anforderung, sondern als Qualitätsanspruch

  • Unternehmerisches Denken und Hands-on-Mentalität

  • Sehr gute Deutsch- und Englischkenntnisse

Nice-to-Have

  • Erfahrung mit OpenEMS, Odoo oder Keycloak

  • Berührungspunkte mit Frontend-Entwicklung, insbesondere Blazor/WebAssembly

  • Hintergrund in der Energiewirtschaft oder IoT

Benefits

  • Schlüsselrolle mit direktem Einfluss auf Unternehmenswachstum

  • Gestaltungsspielraum und Verantwortungsübernahme in einem für unser Unternehmen kritischen Bereich

  • Dynamisches, ambitioniertes Team

  • Attraktive Vergütung inklusive Beteiligungsmöglichkeit

  • Stark wachsendes Unternehmen in einem Schlüsselmarkt für unsere Zukunft

  • Die Möglichkeit, aktiv an der Energiewende mitzuwirken
