Here’s what some of our staff have to say about working at Ridder.

Temro Douw

Product Manager, Management Systems 

“As a product manager, I devise and develop new tracking and management systems that enable growers around the world to tackle challenges in labour and information management. I also search for suitable solutions to the key issues affecting growers today, such labour shortages and shrinking profit margins. What I like about this work is that our smart solutions help growers and their employees make day-to-day greenhouse operations easier and more enjoyable. Working together to make the impossible possible is what gives me the greatest satisfaction.”

Jerre de Blok

Product Manager, Water Treatment

“Using water efficiently is not only good for your wallet, but it’s also good for the environment. I think it’s great to work for a company that provides the building blocks for this. In my role as product manager for Water Treatment, it’s always a challenge to develop suitable solutions that meet our customers’ water challenges, whether they grow in the Netherlands, Mexico or China.’
