Mechanical Design Engineer (All Levels)

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 UAVs.

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.

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.

H3Xs 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 worlds 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.
