• Documentation & Reporting
  Document designs, including schematics, bills of materials, and technical documentation, and present progress and results clearly in both French and English.

Join a Startup That’s Redefining Access to Water

At Kumulus Water, we’re solving a simple but urgent problem: how to bring clean drinking water where it’s needed most. Our innovative machines pull water from the air, providing a sustainable, off-grid solution—without the need for pipes or infrastructure.

From schools to hotels to businesses, our technology is already making an impact, cutting plastic waste and offering a reliable alternative in water-scarce regions. With a fast-growing team in Paris, Madrid, and Tunis, and partnerships across Europe, Africa, and the Middle East, we’re scaling quickly—and we need ambitious people to help us grow.

Why You’ll Love This Role

• Work with purpose
  Your work directly contributes to providing clean drinking water and reducing environmental impact.
• Technical ownership
  See your designs move from prototype to deployed products.
• Collaborative culture
  Work in a hands-on, engineering-driven team with short decision loops.
• Real-world constraints
  Design electronics that must perform reliably in harsh environments, from heat to dust and humidity.
• Fast-paced learning
  Gain exposure to a wide range of technical challenges in a startup environment.
• International impact
  Help build products used across multiple countries and contexts.
