Permanent Position

About us: 

Concrete4Change (C4C) is a R&D company that is developing a ground-breaking technology to utilise and permanently mineralise CO2 in concrete.

C4C technology won a wide range of awards including the United Nations (UN) most innovative Net-Zero technology Climate Challenge Cup at COP26 in Glasgow, Royal Academy of Engineering and UN SDG. C4C is partly owned by two of the largest concrete manufacturers in the World (Siam Cement Group and Goldbeck GmBH). C4C is running several projects in partnership with the University of Nottingham, University of Sheffield & University of Warwick (total project value of £4M for 2023-2024).


We are excited to offer an exceptional opportunity for a highly skilled and ambitious Polymer Chemist with expertise in encapsulation, polymer coating, spray drying, formulation, emulsion, microencapsulation, and hollow fiber spinning.
