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 Materials Characterization Scientist to join our Analytical team to support Sublime’s physical and chemical characterization efforts. The ideal candidate will bring deep expertise on the analysis of aqueous solutions and inorganic materials, which are central to Sublime’s decarbonized cement manufacturing process and product. The Scientist will be responsible for serving Sublime’s Product R&D, Process R&D, and Engineering teams through commissioning and maintaining characterization equipment, developing techniques, validating and standardizing analysis methods, and performing testing on material samples. This role will spend significant time in Sublime’s laboratory performing hands-on testing, traveling to nearby shared user facilities to use external characterization tools, analyzing data and reporting results, and collaborating with other team members to understand their characterization needs and recommend/develop appropriate methods.

The position is an individual contributor role reporting to Sublime’s Analytical Manager. This position is full time in person at Sublime’s headquarters in Somerville, MA, with occasional flexibility to work remotely as appropriate based on team and project needs.
