Throughout each trial, you are the crop specialist. You closely monitor crop development, identify deviations at an early stage, and communicate your findings with researchers and colleagues to ensure the successful execution of every trial.

As a Trial Keeper, you play a key role in ensuring that pioneering greenhouse horticulture research is carried out with the highest possible level of accuracy and precision. You will be responsible for several greenhouse compartments and will have access to all the resources you need to successfully deliver your trials.

Around 150 WUR employees work at the Bleiswijk location. As a Trial Keeper, you will be part of the Greenhouse Facility team, consisting of approximately 30 colleagues.

Your qualities

You are a collaborative and proactive professional with extensive crop production expertise and strong interpersonal skills.

In addition, you bring:

At least 5 years of hands-on growing experience in greenhouse horticulture.
A Dutch Spraying licence at the level of advisor.
Knowledge of and experience with greenhouse climate control systems.
Demonstrable experience with tissue culture and Controlled Environment Agriculture (CEA).
Good command of the Dutch language, both spoken and written.
