About Helion

Helion is a fusion power company based in Everett, WA, with the mission to build the world's first fusion power plant, enabling a future with unlimited clean electricity. Our vision is a world with clean, reliable, and affordable energy for everyone. Since Helion's founding in 2013, we have raised $1.5 billion from long‑time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors including Thrive Capital, Light Speed Venture Capital, Soft Bank, and others to propel us forward.

Our current prototype, Polaris, has reached record‑breaking plasma temperatures of 150 million degrees Celsius (13keV). Helion is continuing to iterate and is on the path to the world's first fusion power plant, Orion.

Helion is hiring an entry‑level Mechanical Engineer to oversee hardware designs for Helion's fusion generator prototypes. The role involves tackling versatile engineering problems essential to deploying fusion energy to the world and driving culture on a small but expanding team.

• Apply both engineering first‑principles and method‑based thinking to challenging problems.
• Use 3D CAD software (e.g., NX, Solidworks) to design fusion hardware.
• Perform analysis with tools such as ANSYS and hold design reviews to gather feedback and iterate to a fully functioning system.
• Learn from experts to expand your engineering skillset and domain knowledge.
• Work hands‑on alongside experienced technicians to improve your hardware designs.
• Fix hardware issues as they arise on integrated fusion generators.

• Bachelor's degree in Mechanical Engineering or related field.
• 1‑2 years of collegiate internship or project team experience (e.g., SAE, Rocket Club) that includes working with versatile teams managing complex engineering projects and schedules.
• Hands‑on exposure to a variety of engineering disciplines (mechanical, electrical, fluids).
• Experience with 3D CAD software (e.g., NX, Solidworks).

• Medical, Dental, and Vision plans for employees and their families.
• 31 Days of PTO (21 vacation days and 10 sick days).
• 10 Paid holidays, plus company-wide winter break.
