About the company:

Sublime is developing a breakthrough process to make low-carbon cement. The technology replaces the industry's legacy fossil-fuel-intensive thermal calciner process with an electrochemical process that produces low-carbon cement at ambient temperatures with renewable electricity. Sublime was started in 2020, as a spin-out of Yet-Ming Chiang's lab at MIT (Form Energy, A123, American Superconductor, 24M, Desktop Metals).

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.

This is an exciting opportunity to transform how the world makes cement. Sublime System seeks a creative and dynamic Engineer in the development of novel processes, including testing and operation of pilot plant scale systems. Your role will focus on various chemical processes within the Sublime technology. You will work closely with our R&D and Engineering teams to scale the system from the bench top to pilot and then industrial scale.

You will be responsible for equipment research, vendor outreach, equipment installation and testing, as well as the development and execution of production runs at pilot scale. You will help maintain pilot equipment and implement process improvements.
