Mechanical Engineering Intern

What we’re building

The marine industry supports recreation, global commerce, and national defense. And yet it runs on technology that hasn't meaningfully changed in fifty years. Until now.

Arc is on a mission to electrify the marine industry. We're rethinking powertrains, software, and vessel designs from first principles. And we're already executing. We started with consumers to develop and harden our core technology. We’re now scaling production of our flagship model with new models and sectors on the horizon. Now we’re extending our platform to commercial applications, starting with tugs, ferries, and defense, with years worth of signed contracts and a pipeline that spans every vessel type on the water.

The technology is proven, the momentum is building, and the opportunity is enormous. The marine industry is going electric and Arc is building the platform that powers it

Who we’re looking for

We’re looking for someone who’s fired up by our mission and ready to build. You’ll thrive here if you adapt quickly, take ownership, and care about the details. 

You will join our Mechanical Engineer team as a summer intern from June 14th-August 20th 2027. You will work from our headquarters in Torrance, CA. Given that we’re a startup, you will be working in a fast-moving, dynamic environment that requires adaptability. That said, here are some responsibilities and qualifications we expect to stay relatively constant for this role.

What You'll Do

• Designing and releasing hardware, with mentorship from a full-time engineer, in areas such as:
  • Composite structures, Interiors & Mechanisms, Marine Systems, Test Fixtures, or Tooling
• Owning a defined project from requirements through design, prototype, and test over the course of your internship
• Building and testing prototypes in the shop and on the water, and helping root-cause failures
• Creating CAD models, drawings, and supporting analysis for parts and assemblies
• Presenting your work and results to the engineering team

Minimum Qualifications

• Currently a junior or senior pursuing a Bachelor's degree in Mechanical Engineering or a related engineering field
• Hands-on engineering experience through a prior internship, project team, research, or personal projects
• Proficiency in a 3D CAD tool (NX, CATIA, or SolidWorks)
• Solid grasp of mechanical engineering fundamentals such as statics, mechanics of materials, and fluids
• Willingness to get hands-on with fabrication, assembly, and testing
• Ability to explain and defend your design decisions
