Mechanical Engineer

Sublime is developing a breakthrough process to make low-carbon cement. The technology replaces the industry's legacy fossil-fuel-intensive thermal calciner process with an electrochemical process that produces low-carbon cement at ambient temperatures with renewable electricity. Sublime was started in 2020, as a spin-out of Yet-Ming Chiang's lab at MIT (Form Energy, A123, American Superconductor, 24M, Desktop Metals).

Background & Overview 

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 Mechanical Process Engineer aid in the development of Sublime’s downstream processing.  As a member of Sublime Systems’ small but growing team, the right individual will be a key technical resource in the scale up of Sublime’s technology.  This is an exciting opportunity to combat global climate change by transforming how the world makes cement. The role will initially focus on installing and commission cement blending equipment in the Sublime Pilot plant but will also be heavily involved in conceptual commercial scale design. The ideal candidate will be results-driven, detail-oriented, organized, and able to thrive in a fast-paced environment.
