Advanced Manufacturing Engineering Intern

About H3X Technologies

H3X is building America's advanced electric motor company, powering next-generation platforms in aerospace, defense, and marine. Our integrated motor drives deliver 12+ kW/kg, roughly 3x the power density of competing solutions. We're now scaling to megawatt-class systems, with customers working on everything from supersonic aircraft to turbine power generation for AI datacenters.

Our team brings together engineers and operators from aerospace, defense, and motorsports, with deep expertise in electric machines, power electronics, material science, and advanced manufacturing. We're a small, fast-moving team doing hard engineering that matters, and we're looking for people who want to do the best work of their careers alongside us.

H3X is looking to hire an advanced 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 for a full time Spring Intern, but also have availability for Summer 2027 and extended Co-Op positions.

Joining H3X means working on hard, meaningful problems with a skunk works-style team that's laser-focused on building exceptional products. We're deeply vertically integrated and have a very tight design-build-test loop, which lets us move from concept to hardware at unmatched speed. We've gone from idea to shipping product in less than two months.

We're a small, highly skilled team where everyone carries real responsibility and shares an extreme ownership mentality. We stay focused on the critical path, keep bureaucracy to a minimum, and structure everything around delivering results. You'll learn and grow faster here than you would anywhere else.

You'll work alongside world‑class…
