<div> JOB PURPOSE: At H3X, we are building the most advanced electric motors in the world for sustainable aviation, marine, industrial, and defense applications. At 12 kW/kg continuous, the HPDM family of integrated motor drives is a step change in electric propulsion technology and removes one of the main barriers blocking widespread proliferation of electric and hybrid aircraft. Our motors range in size 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. These offerings extend the performance, efficiency, and reliability of the HPDM family into new markets like marine and UAV’s. THE ROLE: Mechanical design engineers are responsible for bringing new designs to life from clean sheet concept generation through early prototype testing. Mechanical Design Engineers 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.

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. H3X takes pride in their multidisciplinary approach, relentless dedication, high capital efficiency, and Skunkworks-style execution.  H3X has raised over $30M with backing from top VC firms and strategic firms, including Lockheed Martin, Hanwha, Y Combinator, Cubit Capital, Metaplanet, TechNexus, and Liquid 2 Ventures.  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.  H3X is an equal opportunity-affirmative action employer and considers all qualified applicants for employment based on business needs, job requirements and individual qualifications, without regard to race, color, religion, sex, age, disability, sexual orientation, gender identity or expression, marital status, past or present military service or any other status protected by the laws or regulations in the locations where we operate. <a href="http://www.h3x.tech">www.h3x.tech</a> </div>

H3X makes high power density electric motors for sustainable aviation, marine, industrial, and defense. Our motors have integrated drives, range in size from 40HP to 40,000HP, and are 3X lighter than competitors.
