Machine Learning Engineer (m / f / d)

Digitalization and energy transition in one sentence? That’s what we do at Green Fusion!

Our software holistically optimizes energy systems in the real estate sector, helping to combat climate change through digitalization and automation. We reduce emissions and energy consumption, actively advancing the energy transition.

Tasks

As an ML Engineer , you’ll support our Sector Coupling team building the next generation of intelligent Energy Management Systems (EMS). You will enable high-accuracy model predictions and optimizations through long-term learning from our data to save energy every single day.

• You will design and improve machine learning models for time-series forecasting and nonlinear optimization, taking them from concept to deployment.
• By working alongside data scientists and energy engineers , you will bring forecasting and optimization models into our EMS production environment (Cloud and Edge).
• Maintain and improve ML pipelines (using tools like Prefect and MLFlow ) to support the full model lifecycle—from experiment tracking to training and validation.
• Act as the guardian of our data. You ensure feature engineering for time-series, asset telemetry, and market data is robust. You also lead the monitoring of model quality, handling concept drift and performance evaluation.
• Lead the development of digital twins and simulation environments to safely test how our EMS interacts with components before they touch real hardware.
• You will collaborate with embedded and platform teams to integrate your work into the GreenBox edge device and backend services.

Ein nachhaltiges Energiemanagement in der Wohnungswirtschaft ist nicht nur bald gesetzlich verpflichtend, sondern darüber hinaus ein aktiver Schritt gegen den Klimawandel, hin zu einer grüneren Zukunft für uns alle.

Durch eine signifikante Reduzierung des Heizenergieverbrauchs in Immobilien können nicht nur Ressourcen und Kosten gespart, sondern auch die CO2-Emissionen deutlich gesenkt werden.

Und mit Hilfe der Digitalisierung der Anlagen können diese effizient betrieben werden - automatisiert, vorausschauend und sich selbst optimierend. Probleme können zudem früher erkannt und direkt behoben werden.

Klingt zu schön um wahr zu sein? Nein, mit Green Fusion wird genau das möglich! Wir digitalisieren nicht nur Heizungskeller, wir automatisieren und optimieren den gesamten Betrieb und sorgen für die reibungslose Transformation hin zu regenerativen Systemen. Für maximale Effizienz und Nachhaltigkeit in der Wohnungswirtschaft.
