About The Position

Arc is working to electrify the marine industry by developing electric powertrains, software, and vessel designs. The Manufacturing Engineering Intern will join the Manufacturing Engineering team at Arc’s Torrance headquarters, working alongside engineers, technicians, supervisors, and quality partners on production challenges. With mentorship from a full-time engineer, the intern will own a scoped improvement project from process observation and data collection through implementation and measurement. The role is hands-on and involves spending time on the production floor, learning from the people doing the work, and translating ideas into practical improvements. The internship term is June 14–August 20, 2027, onsite in Torrance. The base pay is $36 per hour. Arc also offers interns boat days, access to traditional and Roth 401(k) plans, PPE and ergonomic-equipment reimbursement, relocation assistance, mentorship opportunities, and daily lunches, snacks, and coffee while onsite.
