Working as a Mechanical Engineer at CIWI

At CIWI, you design machinery for water treatment systems and take an active part in building them. One day, you might be drafting a reactor tank in SolidWorks; the next, you could be at a pilot site, troubleshooting why a pump isn’t performing as expected. You will work full-time, based in Delft, with time spent both in the workshop and out in the field.

What are we looking for?

We are looking for a mechanical engineer who wants to build what they design. At CIWI, you will work on electrochemical systems that use salt, steel, and electricity right on-site to produce the substances needed for water purification.

You will independently design reactor tanks and piping using SolidWorks, and select the necessary pumps, valves, and sensors. You will coordinate production with suppliers, participate in the assembly process in the workshop, and test the systems on-site. If a pilot project doesn’t go as expected, you will work with your team to identify the root cause and adjust your design accordingly.

What you bring to the table

You want to know whether your designs actually work in practice. That’s why you’re just as comfortable in the workshop or at a pilot installation as you are behind your screen. Here’s what you bring:

• You have completed a degree in Mechanical Engineering or a similar field. Professional experience in the sector is a plus.
• You are capable of creating designs and technical drawings independently using SolidWorks.You have a basic understanding of fluid dynamics and hydraulics, and you know how to read a pump curve.
• You enjoy hands-on work and want to see how your designs perform in real-world conditions.
• You are willing to adjust your plans based on the results of measurements or tests.
• Experience with plastic piping, plastic welding, or water technology is a definite advantage.

Why you’ll want to work at CIWI

You will be part of a small team that handles the entire process: design, construction, and testing. This allows you to quickly see the outcome of your designs and gives you the freedom to test and implement improvements yourself. CIWI originated from TU Delft and YES!Delft and is based on the Molengraaffsingel in Delft.

• A full-time position (40 hours per week).
• A gross monthly salary between € 2,800 and € 3,500, depending on your experience.
• 25 vacation days plus 13 additional leave days (ADV)—accrued because you work 40 hours a week, while the collective labor agreement (CAO) is based on a 38-hour workweek.
• Employment terms and a pension scheme in accordance with the ‘Metaal & Techniek’ (Metal & Technology) collective labor agreement.
• The opportunity to receive stock options
• Short lines of communication, room for professional growth, and early responsibility for your own work.
