Kumulus Water

At Kumulus, we make clean drinking water from air where people need it. Our air water generators turn atmospheric humidity into high-quality, mineralized water on site, pairing smart engineering with simple, human design.

Our solutions are installed in offices, off-grid sites, schools, and communities that want a reliable and sustainable alternative to bottled or piped supply. Our water-as-a-service model covers installation, monitoring and maintenance so water stays safe and consistent day after day.

Behind our solutions is a team that cares about impact as much as innovation. We reduce plastic and logistics, improve daily well-being, and help clients gain independence from fragile infrastructure. Clear goals, practical solutions and real-world results guide our work.

Since our conception, our goal has been clear: revolutionizing water access. We are looking for people who enjoy solving concrete problems and seeing their ideas come to life in the field. You are curious, collaborative and comfortable with taking ownership. You value clarity, quality and responsibility.

Our roles span engineering and product (mechanical, electrical, thermal, embedded, cloud and data), industrialization and supply chain, field operations and quality, as well as sales, partnerships, marketing and customer success. Different profiles, one shared mindset.

If you want to learn fast, work in an organisation that combines sustainability with deeptech solutions, and help build the next generation of water access, you will feel at home here.

You will work in an international environment across Europe, North Africa and the Middle East, with teams based in Paris, Madrid, Tunis and Riyadh. English and French are commonly used. Some roles include travel to client sites for pilots and deployments.

We are a mission-driven startup, which means short feedback loops, hands-on collaboration between teams and visible outcomes. We celebrate field wins, share data openly and keep safety and water quality at the center of every decision.

You will see your work create real change, from a school gaining on-site water to a company cutting plastic and logistics. If that sounds motivating, let’s talk!
