Mechanical Engineering Intern

Arc Boat Company•Torrance, CA

69d•Onsite

About The Position

Our vision is to electrify all waterborne vessels, and we're starting with electric water sport boats. Gas boats dominate today's marine industry not because of great product offerings but because of a lack of better alternatives. Boaters have grown accustomed to vehicles that feel stuck in the 1980s: unreliable, expensive, loud, noxious, and a nightmare to own and operate. They're also awful for the water and air they reside in. By contrast, electric boats are superior in nearly every way: not only are they far more reliable and less costly to operate, but they're also quieter, quicker, and cleaner, with no fumes or pollutants. However, they've been held back by both the technology and the talent to make them truly competitive with gas alternatives. That's Arc's opportunity. Using modern, aerospace- and automotive-inspired techniques, we're building our hulls, batteries, cooling systems, firmware, and software together to deliver the next generation of watercraft. We are looking for someone who is excited by our vision, eager for a challenge, and willing to learn on the job. We pride ourselves on transparency and operate in a lean, high-trust environment that encourages everyone to take ownership of their domain. You will report directly to our Manager, Vehicle Engineering as a summer intern from June 15th-August 21st 2025 and 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.
