Sublime Systems is a technology company commercializing affordable, ultra-low-carbon cement. Sublime's breakthrough replaces the industry's legacy fossil fuel-fired kilns with an electrochemical system that operates at ambient temperature, eliminating the use of fossil fuel and the need for limestone, resulting in low-carbon, low-embodied energy cement. This technology has the potential to drive gigaton-scale CO2 reductions in an industry responsible for 8 percent of global emissions. Sublime is backed by mission-aligned investors, including The Engine, Prime Impact Fund, Energy Impact Partners, and Lowercarbon Capital. We are building a diverse and collaborative team of folks who are "amped about cement" (pun intended), who share our values (excellence, creativity, and teamwork), and our motivation to create a better world. 

Sublime Systems seeks a creative and dynamic R&D Co-Op or Intern to contribute to the development of our cement manufacturing process. The co-op or intern will be responsible for conducting research including hands-on lab-scale testing, data analysis, and literature reviews. As a member of Sublime Systems’ small but growing team, the R&D co-op or intern will work closely with the company’s experienced researchers and will receive extensive mentorship. This is an exciting opportunity to combat global climate change by transforming how the world makes cement. The role will focus on the development and testing of Sublime Systems’ decarbonized cement. This role is expected to be hands-on, with a significant amount of time spent engaging in lab testing.
