Mechanical Design Engineer

Job Purpose

At H3X, we are building the most advanced electric motors in the world for sustainable aviation, marine, industrial, and defense applications. Our HPDM family of integrated motor drives achieves 12 kW / kg continuous, enabling propulsion with higher power density. Our motors range from 30 kW to 30 MW, include integrated drives, and are 3x lighter than competitors' systems. H3X also leverages the HPDM platform in integrated systems such as the HPDG-30 hybrid powerplant and the HPDM-90S submersible units, extending performance, efficiency, and reliability into markets like marine and UAVs.

About the Role

Mechanical design engineers are responsible for bringing new designs to life from concept through early prototype testing. They will work with highly interdisciplinary teams to bring H3X products to life. The engineering team operates like Skunkworks – small, highly technical, and very fast. All mechanical design engineers are given significant design freedom and will be directly responsible for flight-critical parts.

The Company

H3X Technologies is a U.S.-based manufacturer of electric motors for sustainable aviation, marine, industrial, and defense applications. They have developed a family of integrated motor drives that can scale in power from 30kW to 30MW with power densities as high as 12 kW / kg and best-in-class efficiency. This high performance is enabled by novel scalable core technology and proprietary manufacturing processes for motor stacking, winding, and assembly. The design, manufacturing, and testing of their products is done in-house at their headquarters in Louisville, Colorado.

H3X's world-class team is composed of experts from Tesla, SpaceX, GE Aviation, and Siemens with deep knowledge in electric machines, power electronics, material science, control systems, and advanced manufacturing. They take pride in our multidisciplinary approach, relentless dedication, high capital efficiency, and Skunkworks-style execution.

H3X has raised over $30M and has backing from top VC firms and strategic firms including Lockheed Martin, Hanwha, Y Combinator, Cubit Capital, Metaplanet, TechNexus, and Liquid 2 Ventures to deploy capital for rapid scaleup.

H3X is poised to become the world's leading supplier of advanced electric motors by 2030 to drive deep decarbonization in aviation, marine, and heavy industrial applications and unlock next-generation electrified defense technology to strengthen national security.
