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 Project Engineer excited to join a promising carbon capture startup working on the development of molten salts as a novel CO₂ sorbent material. The Project Engineer will be responsible for execution of Mantel’s demonstration plant design and build. This position will serve as the project lead, working with Mantel’s senior design engineers and coordinating with multiple EPCs, consultants, equipment vendors, and customer engineering/trades/operations to complete detailed design, build, and installation of a First Of A Kind demonstration unit. Specific technical tasking includes process analysis/calculation/modeling, equipment specification including specification/data sheet review, HAZOP execution, and cross-discipline coordination with Mantel product and R&D teams. Additional tasking includes project schedule ownership, facilitation of weekly status meetings, internal and external technical presentation and reporting, technical deliverable review and tracking, and coordination with management on project staffing. Mantel is looking for a well-organized, versatile technical problem solver who can think outside the box and communicate effectively in a multi-disciplinary team environment.
