Scientist Jobs in Teltow

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 a Senior Data Scientist , you will be the lead architect of the decision-making logic within our Energy Management System (EMS). You will define the mathematical core of the system : designing how it predicts, reasons, and optimizes energy flows in real-time, a complex "time-based decision" problem in the transition to green energy.

Your tasks :

• Create the high-level optimization frameworks (MILP, NLP, or Stochastic Programming) to manage residential energy flows across heat pumps, thermal storage, EVs, and batteries.
• Design and tune closed-loop control strategies to ensure system stability, robustness against model / reality mismatch, and seamless integration of high-level optimization with devices constraints.
• Utilize Stochastic & Learning-Based Control (e.g. Markov Decision Processes (MDPs), Reinforcement Learning, or Model Predictive Control (MPC) to handle the uncertainty of weather, prices, and human behavior.
• Develop ML models that respect real-world constraints. You ensure our algorithms "understand" the thermal inertia of a building or the degradation curves of a lithium-ion battery.
• Build high-fidelity simulations to validate algorithm performance against historical data before deploying code to edge devices and cloud environments.
• You don’t just write formulas; you architect and implement complex models from scratch in Python, ensuring they are robust enough to run in a cloud-to-edge environment.
• Act as a senior voice in technical sessions. You will mentor junior team members and help navigate complex problem-solving and define the algorithmic requirements that guide our product roadmap.
• Work closely with Energy Engineers and Backend Developers to translate math into reliable, production-grade services that save customers money and CO2.

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.
