At 1KOMMA5°, we pursue a clear vision: Living on wind and sunlight forever for free To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?
We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.
Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.

The CTO Office at Heartbeat AI GmbH sits at the intersection of product, engineering, organizational design, and strategic operations. You will report to the Chief of Staff and work in close proximity to the Heartbeat AI GmbH executive team at a moment when the product-tech organization is scaling and driving a fundamental shift toward AI-driven ways of working.
Drive cross-team coordination: You triage incoming requests, coordinate across teams, and ensure priorities don't get lost in a high-velocity organization
Turn cross-functional initiatives into scalable processes: You lead projects end-to-end — from scoping and alignment through to delivery — and ensure the solutions you ship are scalable
Apply a product builder lens: Whether a topic calls for a requirements brief, a lightweight prototype, or a structured analytical frame, you bring genuine depth to the problem
Prepare leadership to act decisively: You produce the decision materials, pre-alignments, and follow-through structures that convert strategy sessions into clear ownership and next steps
You have 2–4 years of experience in product management or a strategy and operations role at a technology company
You have a track record of driving cross-functional projects independently, from scoping through to delivery
You move naturally between operational detail and strategic framing, writing a sharp requirements brief and running a stakeholder alignment session are equally comfortable for you
You communicate with clarity and directness in both English and German, written and spoken (C1/C2 in both)
You are comfortable operating in ambiguity and in close proximity to senior leadership — experience working directly with founders or executives in a startup or scale-up environment is a strong plus
You take ownership seriously and hold yourself to a high standard: when something lands on your plate, it gets done excellently
You have a genuine interest in how AI is changing the ways of working

1KOMMA5° wurde im Juli 2021 mit dem Ziel gegründet alle Gebäude zu elektrifizieren und CO2-neutral zu machen. Durch den Einsatz von Solaranlagen, Stromspeicher, Wärmepumpe, Klimaanlagen und Ladeinfrastruktur in Verbindung mit einer intelligenten Steuerung wird Wind- und Sonnenstrom automatisch dann genutzt wenn er günstig ist und am Markt verkauft wenn er teuer ist.
Das technologische Herzstück ist “Heartbeat AI”. Die KI-Software verbindet die Energiesysteme direkt mit der Strombörse und steuert jedes einzelne System nach individuellen Fahrplänen in Echtzeit. So wird immer der günstigste und sauberste Strom bereitgestellt, ob vom eigenen Dach oder vom Strommarkt.
Inzwischen steuert Heartbeat AI ca. 50.000 Energiesysteme und so über 450 Megawatt - das größte virtuelle Kraftwerke für Privatkunden in Europa mit einem Strompreis unter 10 Cent je kWh im Jahresdurchschnitt.
1KOMMA5° hat bereits über 120.000 Kunden und gilt laut EUPD Studie seit 2024 als europäischer Marktführer. Zurzeit betreibt 1KOMMA5° über 80 Standorte mit rund 2.500 Mitarbeitenden in sieben Ländern in Europa und Australien.
