Business Operations Co-op

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.
