Candidates should be pursuing a bachelor's or master's degree in mechanical engineering or a related field, have CAD proficiency and a grounding in mechanical engineering fundamentals, and bring hands-on experience from coursework, projects, or personal builds. The internship is full-time and onsite for at least 12 consecutive weeks. California-based interns are paid $38-$41/hour, with actual pay varying by qualifications and experience. Applicants must be U.S. citizens or lawful permanent residents due to ITAR requirements.
