Job Description Job Description About the RoleAt 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 is looking to hire a manufacturing engineering intern to support the low volume production line across all the HPDM product lines. This is not an ordinary internship- you will be given the full responsibility of a manufacturing engineer. The production team is rapidly deploying new processes and improvements to meet the growing demand for the HPDM product lines. A high degree of self-motivation and responsibility is required as you will be given significant freedom and will be directly responsible to produce your assigned parts. We are looking to hire a full time intern with a focus on the Fall 2026 Semester for a minimum of 12 weeks, but open to extended periods as well based on candidate availability.ResponsibilitiesREQUIREMENTS / CONCEPTWork with design engineers to establish production requirementsConceptualize new and novel approaches to solve manufacturing problemsPropose new materials, fixture concepts, equipment or otherDESIGN AND ANALYSISDesign tools and fixtures to improve manufacturing processesAnalyze recurring manufacturing discrepancies and implement solutionsCollaborate with design engineers on implementation of manufacturing feedbackPRODUCTION VALIDATION AND INTEGRATIONExecute first application and testing of new fixtures and process improvementsInterface with manufacturing engineers and assembly techniciansCreate, implement, and revise process plans and mBOMs to support productionLead LEAN manufacturing processes in support of continuous improvement initiativesRequired QualificationsPursuing a Bachelor's or Graduate Degree in Mechanical Engineering or similarGPA of 3.0 or higherHands-on experience assembling mechanical systemsSolidWorks proficient (or similar)Excellent written and verbal communication skillsOrganized and strong attention to detailExceptional understanding of engineering fundamentalsAction biased, results-driven mentalityWillingness to learn quicklyPreferred QualificationsExperience with manufacturing processes (machining, assembly, & composites)Experience with producing 2D part drawings and GD&TExperience with inspection methods and metrology equipmentBenefits & Compensation$23.00 - $37.00 / hr based on school level & experienceRelocation stipendMonthly company eventsFriday Team LunchThe CompanyH3X 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.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.
