Joining H3X means working on hard, meaningful problems with a skunkworks-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 engineers and builders who are pioneering electric motor technology at scale on some of the coolest programs in the industry, from supersonic aircraft to power generation for AI datacenters. If you want your contributions to be visible and your work to directly shape American reindustrialization, you'll feel at home here.

Be Relentless Never give up, persevere until the job is done. Run toward problems, not away from them. Grit is key.

Gain insight through humility Approach every challenge with a learner’s mindset. Stay open to feedback, listen to others, and deepen your understanding through self-awareness. Put your ego aside and seek the truth in every discussion, especially when leading others.

Distill & Simplify Eliminate unjustified complexity and simplify wherever possible, whether in requirements, design, or execution. Use first principles thinking to distill every problem to its essence. Less is more.

Find your flow Engage fully and work with intention. Find the rhythm and deep focus that lets you do your best work. Discover your Ikigai - where your strengths, passions, and purpose meet and drive your personal fulfillment and team success. That is when the magic happens.

SEND (Solve, Evolve, Nail It, Deliver) Devise the best solution with the information at hand, test it, learn from it, and iterate quickly until you nail it. Nothing works perfectly the first time, but you should never hit the same issue twice. Stay laser-focused on solving customer problems and delivering solutions that create real value.
