Chief Technology Officer leading innovation in Low Emission Concrete and CO2 capture

** Join the Climate-Tech Revolution at Concrete4Change (C4C)**

Position: Senior Process Engineer (Job title flexible)

Location: Nottingham, UK

Type: Permanent, Full-Time

Start Date: Immediate

About Us

Concrete4Change (C4C) is a pioneering R&D company developing breakthrough technology to permanently mineralise CO₂ in concrete. Our additive production process was recently scaled up 10×, and we are now focused on creating a fully licensable commercial flowsheet—demonstrated with “steel on the ground.”

We are finalising the construction of a mini full-flowsheet pilot plant at our Nottingham facility. This plant will operate over the next six months before integrating with real flue gas. The operational data and lab results will feed into our process design documentation and models, supporting the design of a 100× commercial demonstrator.

C4C has won multiple prestigious awards, including the UN Climate Challenge Cup at COP26, and is partly owned by Siam Cement Group and Goldbeck GmbH. We collaborate with the University of Nottingham, Leeds, Sheffield, Warwick, and leading manufacturers such as Holcim, CRH, Marshalls, and Ibstock.
