Job Description

CarbonBuilt addresses climate change by permanently and cost-effectively reducing cement usage and storing CO₂ in concrete. Our innovative Reversa™ technology was awarded the grand prize in the NRG COSIA Carbon XPRIZE competition in 2021, and we are presently focused on making the leap from two successful pilot demonstrations to our first commercial plant. At CarbonBuilt, our employees will have the opportunity to make a global and long-lasting impact on the defining challenge of our time – climate change. As we prepare for our commercial introduction, CarbonBuilt is seeking a concrete scientist to join our rapidly growing team.

You will work directly with CarbonBuilt’s engineering team to design innovative low-carbon concrete formulations that will cure with gaseous CO₂ via mineralization. You will conduct research including hands-on lab testing, data analysis, literature review, and field testing/demonstration.


  • M.S. in Civil Engineering, Materials Science/Engineering, Geochemistry, Chemical Engineering, Chemistry, or other comparable fields plus one or more years of relevant experience in research and development on cement/concrete, or Ph.D. in a related field

  • Knowledge of cement chemistry, hydration reaction, and carbonation reactions

  • Knowledge of design and development of alternative cementitious materials  

  • Ability to extend principles of reactivity mechanisms from cement to alternative binders

  • Ability to select and perform analytical techniques for characterization of alternative binder systems to develop composition-reactivity-property relationships

  • Familiarity with statistical methods including design of experiments and machine learning methods


  • Develop a screening methodology and qualification criteria to assess the suitability of binder systems

  • Exploit hydration/carbonation reactions of cementitious materials to develop sustainable binder systems

  • Develop mechanochemical routes to activate hydration/carbonation reactions of binders for concrete applications

  • Conduct laboratory functions, including hands-on testing, materials characterization, concrete testing

  • Travel to project sites to demonstrate the technology at a pilot scale (for up to 2 months per year; e.g., 4-8 1-week trips)

  • Maintain & calibrate testing equipment

  • Other duties as assigned by the Head of Engineering
