Senior Data Scientist Optimization (fmd)

Digitalization and energy transition in one sentence
Thats 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 dont 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.

Requirements

We know that nobody fits a job description 100%. If you see yourself in most of these points and are passionate about our mission wed love to hear from you!

• You are deeply familiar with mathematical optimization. You have hands-on experience with solvers for MILP NLP or MINLP (e.g. CasADi Gurobi Pyomo).
• You have in-depth statistical knowledge and experience in time-series forecasting specifically handling uncertainty through stochastic modeling.
• You are proficient in Python and can design complex model architectures from the ground up keeping the big picture (end-to-end thinking) in mind.
• You enjoy the messy reality of hardware. You are eager to learn the specifics of heat storage hydraulic balancing and electrical constraints to ensure your code works in the real world.
• You can explain the Why behind a complex stochastic model to a non-technical stakeholder and lead a brainstorming session on system architecture with ease.
• Bonus Points: You bring experience in energy usage prediction Reinforcement Learning IoT/Edge deployments or energy management systems (EMS)a plus but not a must.

Benefits
