Spark Cleantech is a fast-growing and innovative start-up developing a breakthrough process that replaces the combustion of hydrocarbons in high-temperature industrial furnaces and in materials production with an alternative that is not only fully decarbonised, but also economically competitive and requires only minimal adaptation to existing industrial processes.

To support this growth, we aim to hire around 20 talented individuals to join our team who share our vision, contributing to a more sustainable world, and our values: positivity, passion, and high standards.
