Build at the frontier, where superconductors, cryogenics, and megawatts meet

Humanity sits around 0.7 on the Kardashev scale, and we won’t reach Type I on batteries that wear out. Spinor is building the storage layer for that future: instant, predictable power at a scale that will soon train trillion-parameter models, steady the grid around fusion plants, and launch payloads off the surface of the Moon.

We’re building the real-life flux capacitor: Superconducting Magnetic Energy Storage (SMES), a battery that stores electricity in the magnetic field of a superconducting coil instead of through chemical reactions. It never degrades, discharges megawatts in milliseconds, and is the most efficient form of energy storage ever conceived.

Our engineering spans four disciplines at once: superconducting materials, megawatt-scale power electronics, cryogenics, and vacuum systems. At Spinor, you'll get your hands on all of them.

Spinor's founders came from SpaceX, where they designed Starlink solar arrays and scaled production to 70 satellites per week. We are bringing the same first-principles engineering, rapid iteration, and design-for-scale mindset to energy storage.

You will own consequential hardware architecture and first schematic through bring-up, validation, and field deployment.

The Role

Spinor Energy seeks extraordinary students to join us for engineering roles in Summer 2027. As an intern, you will work closely with your mentor and other employees who will help you apply your knowledge and grow your skills on projects that have a significant impact. Internships are available with a variety of engineering roles including thermal and cryogenics, electrical, and mechanical.

Basic Qualifications

• Must be enrolled in a bachelor's degree program in an engineering, physics, or math discipline by the start of employment

• 3+ months of applied engineering experience (internship, laboratory, and personal/team project experience is applicable)

• Demonstrated proof of strong first-principles fundamentals

• Able to work full time, onsite for a minimum of 12 consecutive weeks beginning in May or June 2027

Preferred Qualifications

• GPA of 3.5 or above

• 6+ months experience of application of technical skills outside of the classroom (examples: laboratory, research, extracurricular project teams, volunteering, personal projects or prior internship/work experience)

What We Value

• Build things you're proud of.

• Take responsibility. If something is broken and you can fix it, fix it. See things through.

• Think bigger. Simplify relentlessly. Don't default to the safe answer.

• Desire to win. What we do is hard. We are here to win.

• We're a small team of unusually talented people - engineers who happen to be endurance cyclists, extreme hikers, pilots, and a national spreadsheet champion. What's your thing?
