Manufacturing Engineering Intern

About the Role

Arc is on a mission to electrify the marine industry. This role is for a curious, hands-on engineer who wants to understand how things are built and make the process better. You will join our Manufacturing Engineering team and work on real production challenges with mentorship from a full-time engineer. You will own a scoped improvement project from observation and data collection to solution implementation and results measurement.

Internship Term: June 14–August 20, 2027

Location: Onsite at our Torrance headquarters

Key Responsibilities

• Observe production processes and perform time studies to identify bottlenecks, excess motion, rework, and opportunities to reduce build hours.
• Create and improve work instructions, process flows, and assembly sequences with input from technicians and engineers.
• Design, prototype, and validate tools, fixtures, and shop aids that improve repeatability, ergonomics, and build quality.
• Support root-cause investigations into production issues and help implement corrective actions.
• Partner with design engineering and quality to improve manufacturability and support the introduction of new parts or processes.
• Use build and quality data to compare performance before and after changes, documenting results and lessons learned.
• Present your project, results, and recommended next steps to the team at the end of the internship.

Requirements & Tech Stack

• Pursuing a degree in Manufacturing, Mechanical, or a related engineering discipline.
• Experience building, assembling, testing, or improving hardware through coursework, a student team, research, an internship, or personal projects.
