C-Cube International is a technology company based in Delft that develops sensors and data-driven solutions to measure and predict coating degradation and corrosion on steel structures. Our solutions help industries like offshore wind, oil & gas, and infrastructure make smarter maintenance decisions and extend asset lifetimes. We work with major players like Shell, KLM, and Boskalis, taking on projects across countries all over the world including China, Japan, Malaysia, Singapore, Germany, Belgium, the UK, France, and the United States.

But beyond the technology, we’re a growing international team that values collaboration, curiosity, and initiative. Everyone at C-Cube contributes to real-world projects, shares ideas freely, and learns from one another. It’s a place where you can take ownership of your work, grow quickly, and see the results of what you do.

About the R&D Team

Our R&D team develops the core technology behind C-Cube’s coating and corrosion measurement solutions. The team combines expertise in electrochemistry, mechanical engineering, software development, and product design. They work on improving our sensors, developing new test methods, and translating research into practical tools used in offshore wind, infrastructure, and other industries.
