Scientist l/ll

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 II to contribute to the development of our decarbonized cement. This Scientist 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 that will report to Sublime’s Head of Product R&D. 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.
