Mechanical Engineer, Early Career

We are 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 over $1 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors SoftBank and Lightspeed to propel us forward. Our last prototype, Trenta, completed 10,000 high-power pulses and reached plasma temperatures of 100 million degrees Celsius (9 keV). We are now operating Polaris, our next prototype on the path to the world's first fusion power plant.

This is a pivotal time to join Helion. You will tackle real-world challenges with a team that prizes urgency, rigor, ownership, and a commitment to delivering hard truths – values essential to achieving what no one has before. Together, we will change the future of energy, because the world can't wait.

What You Will Be Doing

Helion is hiring an entry-level Mechanical Engineer to oversee hardware designs for Helion's fusion generator prototypes. You will help solve versatile engineering problems that are important to deploying fusion energy to the world, and be a culture-driver on a small but expanding team. You will report directly to a Mechanical Engineering Manager at our Everett, WA office.

You Will

• Own and understand subsystem designs such as electromagnetic, structural, fluid, thermal, and control systems, and improve their requirements
• Learn from historical engineering approaches, design novel hardware, test your solutions, and integrate them into our fusion devices
• 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 like 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

Required Skills

• 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
• Bachelor's degree in engineering
• Hands-on exposure to a variety of engineering disciplines (mechanical, electrical, fluids)
• Experience with 3D CAD software (e.g. NX, Solidworks) and GD&T

Helion's compensation package includes a competitively benchmarked base salary, meaningful equity grants, and comprehensive benefits. Final compensation is determined through a holistic evaluation of your experience, qualifications, and our commitment to internal equity - ensuring fairness and transparency across our teams.
