About the job
Sublime is advancing a breakthrough, clean, efficient, low-waste process for manufacturing cement, the essential ingredient in the most-consumed human-made material on Earth: concrete. Replacing 200-year-old manufacturing methods that are reliant on kilns running hotter than lava, our near-ambient-temperature, electrochemical technology manufactures industry-accepted cement and critical minerals. We’re partnering with leading general contractors, concrete producers, developers, and technology hyperscalers to deploy our clean, durable, beautiful Sublime Cement® in infrastructure that is defining the future of clean construction. Backed by some of the world’s largest cement producers, leading private investors, and the U.S. Department of Energy, we are assembling a talented, collaborative team that is ‘amped about cement’ (pun intended) and committed to operating on the frontiers of material science, manufacturing, industry, construction, and commercial partnerships, to advance cement innovation that will endure for the next millennium.

Sublime is seeking a Senior Scientist to contribute to the development of our decarbonized cement with special expertise in rheology and milling of cementitious materials. This Scientist will be responsible for managing and 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. This Scientist 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.
