Weheat is re-engineering heat pumps because we believe this product plays a key role in the energy transition and deserves radical innovation. We redesign everything starting at the circuit board level to make heating affordable and simple. Our software is just as critical: Weheat Intelligence takes over the complexity, so homeowners don’t have to—and can maximize savings on costs and CO₂.

From our factory in Eindhoven, we develop and build our heat pumps. In our new hub in the center of Utrecht, everything the outside world sees comes together: commercial growth, our digital products, and support for installers and consumers. Eindhoven is the high-tech engine; Utrecht is the customer-focused heart.

Weheat is re-engineering heat pumps because we believe this product plays a key role in the energy transition and deserves radical innovation. We redesign everything starting at the circuit board level to make heating affordable and simple. Our software is just as critical. Weheat Intelligence takes over the complexity so homeowners do not have to, enabling lower costs and lower CO₂ emissions.

Weheat has thousands of heat pumps in the field, and every one of them generates data. This role is about what you can see when you look across all of them at once: performance patterns, grid signals, fleet-wide opportunities, and the levers that move the needle at scale.

Your Mission

You identify what is happening across thousands of installations, build models that span the full portfolio, and translate those insights into smarter energy strategies, better product decisions, and grid-ready behaviour. Your work connects the intelligence running inside each heat pump to the larger energy system it is part of.

The Challenge

Fleet Performance Analysis: Identify performance patterns, anomalies and improvement opportunities across the installed base. Where are units underperforming, and why? What does good look like, and how do we scale it?
Energy & Grid Forecasting: Build probabilistic models for aggregate thermal demand, flexibility potential and system inertia across the fleet, integrating dynamic tariffs, PV production and grid signals.
Flexibility & Grid Interaction: Model and optimize how the Weheat fleet participates in energy markets and responds to grid conditions. Turn distributed thermal assets into coordinated grid resources.
Data-Driven Product Feedback: Use fleet data to close the loop with control and hardware engineering. What does field reality reveal about how systems are actually behaving, and what should change?
Real-World ML: Handle missing telemetry, time-series drift, seasonality, edge cases and physical constraints at scale across a diverse and growing installed base.

About Weheat

Weheat is re-engineering the heat pump from the printed circuit board up. Based in our Smart Factory in Eindhoven and our Commercial & Digital Hub in Utrecht, we combine high-tech hardware with intelligent software to accelerate the energy transition. We operate with a flat structure and a focus on scientific first principles: we value data over opinion and rigorous engineering over quick fixes.

What we offer

The opportunity to work on complex, physical problems with direct societal impact (CO2 reduction/Grid Stability).
A collaborative environment with a high density of technical talent (MSc/PhD level).
Autonomy to define the technical roadmap within your domain.
Competitive compensation and the opportunity to grow with a future European market leader.
