Hiring for defense contractors can be challenging for physics majors, particularly for research positions, which tend to be highly competitive and often require a PhD. While physics is typically considered a related major, candidates with degrees in computer engineering, electrical engineering, or computer science may have an advantage. Internships can provide valuable experience; one physics major reported a positive internship experience at a defense contractor, where they were encouraged to apply for full-time positions post-graduation. Overall, securing a job in this sector is not straightforward, especially in a fluctuating job market, but opportunities do exist for physics graduates.
