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.

Position Overview

This is an exciting opportunity to transform how the world makes cement. Sublime Systems seeks a creative and hard-working scientist/engineering co-op to support the development of our technology on the R&D scale. In this role you will gain valuable hands-on experience in small scale reactor design and operation, utilizing a variety of characterization techniques to assess material properties and performance, analyzing and interpreting results, and exposure to experimental planning and prioritization.

The ideal candidate is a hard-working scientist or engineer who thrives in a fast-paced environment with shifting priorities consistent with R&D. This role is expected to be hands-on in the lab assisting in R&D efforts to develop and optimize the Sublime Process to meet material performance metrics. Successful candidates will be results-driven, proactive, and effective in managing their own time efficiently.

This is a paid full time (40 hr/wk) in person position located in Somerville, MA.
