Company: Thermeleon

About the job

Do you want to apply your commercial and analytical skills to sustainable innovation in greenhouse horticulture?

Thermeleon is developing an innovative thermal battery for high-tech greenhouses.

Our technology is already operational in one of the most cutting-edge greenhouses in the Netherlands. A large-scale rollout is planned for this year.
