Senior Project Engineer

Mantel is a climate tech startup supported by Breakthrough Energy, The Engine and New Climate Ventures. Born out of MIT, Mantel was founded by two MIT scientists and a Harvard MBA to develop the material solution to carbon capture. Our molten borates are designed to operate at the high temperatures found inside boilers, kilns, and furnaces – enabling highly efficient carbon capture that has not been possible until now. Carbon capture can be applied across industry to reduce emissions - and even achieve net-negative emissions. By solving for efficiency Mantel can reduce energy losses to near-zero and cut costs in half, unlocking carbon capture’s role in reaching net-zero emissions globally.Mantel is looking for a Senior Project Engineer excited to join a promising carbon capture startup working on the development of molten salts as a novel CO2 sorbent material. The Senior Project Engineer will be responsible for execution of Mantel’s demonstration plant design, build, and commissioning, coordinating with multiple EPCs, consultants, equipment vendors, and customer engineering/trades/operations. This position will serve as the project lead and work jointly with Mantel’s senior design engineers to develop the commissioning plan.
