Ready to shape the future of drinking water? Start your journey as a Mechanical Engineer at PWNT.

As a Mechanical Engineer at PWNT, you play a key role in realizing our innovative water treatment solutions. You are responsible not only for the technical design, but also for the quality, manufacturability, and practical applicability of your designs within our projects. You will work within the Project Engineering & Development group in Amsterdam (at least three days per week on-site) and focus on our proprietary technologies: SIX, ILCA and Cera Mac.

You are involved from the very first sketch: from concept development and prototyping to validation and ultimately translating designs into fully scalable installations. You collaborate closely with fellow engineers, project managers, suppliers, and clients, acting as the technical point of contact within your discipline. With your understanding of mechanical design, standards, and regulations, you create solutions that are technically strong, sustainable, and practically feasible.

In this role, you have the freedom to conduct independent research, explore new ideas, and implement improvements. You work in a close-knit international team with extensive expertise, where knowledge sharing and collaboration are central. The projects are complex, innovative, and internationally oriented — no two days are the same. You work with the latest technologies in a rapidly growing market where water quality and sustainability are becoming increasingly important.
