Help us build the future of circular concrete.
Following the successful operation of our pilot plant in Rotterdam, we are preparing for commercial scale-up. To support this next phase, we are looking for an experienced Concrete Technologist who will play a key role in validating product performance, developing testing methodologies and ensuring product quality as we move towards industrial production.
As Concrete Technologist, you will be responsible for planning, executing and interpreting laboratory testing activities for our innovative cementitious materials.
This is a hands-on role that combines laboratory work, data analysis and technical decision-making. You will not only perform tests, but also help determine which tests matter, how they should be executed and how results should be translated into actionable insights for our R&D, engineering and operations teams.
You will become one of the key technical experts within our materials team and help establish the testing standards for a new generation of circular cement products.
