Mantel is a seed-stage startup backed by leading climate-tech venture capital firms. Mantel, born out of MIT, was founded by two MIT scientists and a Harvard MBA.

Mantel is developing the material solution to carbon capture. We have developed the only liquid phase carbon capture material that operates at high temperatures. Our molten borates enable new process designs that can increase thermal efficiency and reduce the cost of carbon capture and storage by more than 40%. Mantel’s solution will help to reduce CO2 emissions across a range of industrial sources including the generation of electricity with net negative emissions.


Mantel is looking for a research scientist excited to join a promising carbon capture startup working on the development of molten salts as a novel CO2 sorbent material. The position will be required to execute experimental procedures, while also aiding in experimental design and interpretation of results. Initial tasks will be related to scaling up molten salt sample production and salt characterization experiments. In parallel, work related to salt facing material corrosion and selection will be performed. The ideal candidate is comfortable in a lab setting, while being an excellent verbal and written communicator. Mantel is looking for a problem solver who can think outside the box and works well both independently and in a team environment.

Education: Undergraduate degree in chemistry, materials science, engineering or equivalent. Additional research and education is considered a plus but not required.

Skills and qualifications:

·        Experience with analytical chemistry and characterization techniques such as DSC, TGA and SEM. Experimental work related to molten salts is considered a plus but not required.

·        The position will be required to run process simulations along with fluid flow and stress analysis related to the design of a high temperature liquid-gas contactor. Additional experimental work related to prototype design and testing will occur.

·        Experience with process simulations (Ex. Aspen), computational fluid dynamics and stress analysis (ex Ansys Suite) is considered a plus.

·        Experimental work on separations is considered a plus.

Location: Boston based, requires work in Cambridge lab space. Option to be remote when not in lab.

Pay: Highly competitive pay based on experience, option to include equity

This is an exciting opportunity to be an early hire in a new, well-funded company, with significant opportunity for advancement.
