Project Engineer - Paebbl

Paebbl is an industrial resilience company turning captured CO into carbon-storing building materials. We accelerate the natural process of CO mineralisation- in which CO reacts with minerals to form stable carbonates from thousands of years -to a matter of hours, producing a carbon-negative powder that can replace conventional, heavily emitting cementitious materials. Having switched on the world’s first continuous CO mineralisation demonstration plant, we are now scaling from startup execution into structured industrial operations. It is a fast-moving environment where pragmatism, ownership, and the ability to build things that work in the real world matter.

As Project Engineer, you will join Paebbl's Product Development team at an exciting stage of growth as we accelerate the commercialization of our technology. This role sits at the intersection of engineering, product development, customer engagement, and project management, ensuring that technical projects move efficiently from concept through validation and deployment.

You will become a key link between our Product, R&D, Commercial, and Operations teams, helping transform customer requirements into structured development projects while ensuring alignment across internal and external stakeholders. You will work closely with customers, strategic partners, suppliers, and investors to communicate technical information, coordinate product development activities, and deliver projects on time and to a high standard.
