About Weheat

Heating is one of the largest remaining sources of CO₂ emissions in our homes. To tackle that, we want Weheat to become Europe's leading player in residential heat pumps. We develop, test and build our own heat pumps, from first design to production at scale in the Brainport Eindhoven region. What sets us apart: we develop hardware and software together. That makes the heat pump easier to install, and it steers itself smartly on comfort and energy prices. In Utrecht, we drive our commercial growth and build our digital products.

How we work

A mission bigger than you

Going off gas should be the obvious choice for everyone, not a compromise. The better we do as a company, the faster that switch happens. You'll see what you contribute in the product and in people's homes.

If a topic is yours, so is the decision, whatever your job title. You gather input, weigh it up and see it through. Got a question or feedback? Go straight to the colleague who can help. We work without layers or approval rounds: you get trust up front, not after you've earned it.

AI is part of the job

We work AI-first. AI is built into many of the tools we use every day, and we use it wherever it makes our work easier or better.

We grow together

Weheat is a young company. A lot is still being built, and you help build it. Our growth in the Netherlands and the move into Europe create new roles and markets. You get responsibility from day one and work closely with the people who design and build our heat pumps in the Brainport Eindhoven region.

What we offer

• A laptop and phone, with a plan you can also use privately
• Travel allowance
• We cover your full pension contribution
• Worked extra hours? Take them back as time off, or get them paid out
• Fresh lunch every day
• A summer and a winter party
• A key role in the backend architecture of our heat pump platform
