Job description

The Mission

We are looking for a Mechanical Engineer who is hungry, obsessed with building, and ready to drink from the firehose. You won't just be pushing paper; you will be on the floor designing, building, breaking, and iterating on high-consequence hardware.

We are an startup building next-gen pulsed power systems in defense and industry. We are moving extremely fast. We don't have time for red tape, office politics, or "that's not my job" attitudes.

The Role

You will be thrown into the deep end immediately (with mentorship). We don't expect you to know everything on day one, but we expect you to learn fast and think on your feet. You will support the engineering lead in:

  • Rapid Prototyping: Owning the DFM process from concept to physical part using FDM and SLS 3D printing.
  • Production Design: Transitioning prototypes into scalable parts via casting and injection molding.
  • Complex Fixturing: Designing and building test fixtures for High Voltage environments.
  • System Design: assisting in the mechanical design and packaging of full packaged systems.

Who You Are

  • You are a Builder: You have a portfolio of things you've built with your own hands (Formula SAE, Baja, personal robotics projects, or crazy garage builds).
  • You possess "Grit": You understand that engineering is 10% inspiration and 90% grinding through hard problems until they are solved.
  • You are fearless but safe: You aren't intimidated by high voltage or energetic materials, but you respect the physics and safety protocols required to handle them.
  • You want Upside: You aren't looking for a stable 9-5 at a legacy defense contractor. You want to build something that matters.

IMPORTANT: You must be fluent in CAD; we need someone who can model complex assemblies at the speed of thought, not someone who is still learning the interface.

The Technical Stack (The "Wishlist")

We realize you are early in your career. If you are smart and work hard, we can teach you the physics. However, exposure to the following is a big plus:

  • BS in Mechanical Engineering (or equivalent experience).
  • CAD proficiency (SolidWorks, NX, or Fusion 360).
  • Fabrication knowledge: You know how to design for FDM/SLS (additive) vs. Injection Molding/Casting (subtractive/formative).
  • Electromechanical exposure: Experience designing fixtures or enclosures for high-voltage systems.

Why Join Us?

  • Radical Ownership: You will have your fingerprints on hardware that ships.
  • Mentorship: You will work directly with senior engineers on complex, multi-disciplinary problems (HV, Ballistics, Materials Science).
  • High Upside: Join at the ground floor of a fast-growing startup

Note: Due to the nature of our work, candidates must be US Citizens or Permanent Residents (Green Card holders) to comply with ITAR/EAR regulations.

Questions:

What is a technical "rabbit hole" you've fallen down recently just because you were curious?

What is the most physically or mentally demanding task you have ever completed?

Which do you prefer: a perfect design that ships in a month, or a "good enough" prototype that ships tomorrow? Why?
