What the job really is

As a Mechanical Engineering Intern at Pacific Fusion, you will engage in hands-on projects that span the entire development process, from planning and design to assembly and testing. You will work closely with the engineering team on high-priority projects that contribute directly to the advancement of fusion energy systems. This role offers a unique opportunity to gain practical experience in a cutting-edge field focused on clean energy solutions.

Benefits
  • Meaningful, resume-building engineering work on real hardware
  • A chance to design, build, and test real systems
  • Mentorship from experienced engineers in a high-impact environment
  • Exposure to the full product lifecycle—from concept and design to build, test, and operation
  • A collaborative, hands-on, learning-driven culture
  • Daily catered lunch and unlimited snacks
Things to weigh
  • No specific mention of the technologies or tools used beyond CAD software, which may limit exposure to modern engineering practices.
  • The internship requires full-time onsite work, which may not be suitable for all candidates.
  • The role is focused on fusion energy, which is a niche area that may not appeal to all mechanical engineering students.
