About the company:

Sublime Systems is leading a swift and massive transition to a clean cement manufacturing future.

Sublime’s breakthrough electrochemical process avoids the pollution caused by ordinary portland cement’s use of fossil-fueled kilns and limestone feedstock. Sublime instead extracts reactive calcium and silicates from abundant raw materials at ambient temperature, to make ASTM C1157-compliant Sublime Cement™, a 1:1 replacement for OPC in concrete. Because it does not require carbon capture, Sublime’s technology offers a clear path for cost-competitive clean cement manufacturing at scale.

Sublime was founded at MIT in 2020 by Dr. Leah Ellis and Prof. Yet-Ming Chiang, both respected experts in materials science, electrochemical systems, and sustainability research. The company has raised over $200M in funding from leading tech investors, global cement majors, and cooperative agreements with the U.S. Department of Energy’s ARPA-E, IEDO, and OCED award programs.

It currently operates a Somerville, MA-based pilot plant with a >250 TPY nameplate production capacity and is developing its 30,000 TPY first commercial facility in Holyoke, MA.

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 is seeking a Scientist l/II to contribute to the development of our decarbonized cement. This Scientist l/II will be responsible for conducting research to improve the performance of Sublime Cement through literature reviews, designing experiments, performing hand-on characterization and testing in lab, analyzing and interpreting data, and communicating results. The Scientist II will also contribute their expertise to help set technical priorities and research strategy, plan and prioritize experiments, and contribute to the successful operation of our shared laboratory.

This is an individual contributor role. This position is in person at Sublime’s headquarters in Somerville, MA, with occasional flexibility to work from home as appropriate based on team and project needs.
