About Helion
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 $1.5 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors including Thrive Capital, LightSpeed Venture Capital, SoftBank, and others to propel us forward. Our current prototype, Polaris, has reached record-breaking plasma temperatures of 150 million degrees Celsius (13 keV). Helion is continuing to iterate and on the path to the world's first fusion power plant, Orion.
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.

Control and monitor pulsed power systems, including mega-joule capacitor banks and high-energy infrastructure, with a focus on operational reliability and readiness
Own system readiness for experiments, including pre-shot setup, system checks, troubleshooting, and analysis
Identify, diagnose, and resolve issues in high-energy and large-scale vacuum systems to minimize downtime and improve operational efficiency
Apply plasma physics concepts to support experiment execution and interpret diagnostics for magnetic fields, fusion products, and plasma characteristics
Drive continuous improvement of machine operations, including refining procedures, improving system robustness, and reducing variability in experimental results
Collaborate cross-functionally with engineering, science, and production teams to improve system performance and operational throughput
Required Skills:
B.S. with 4+ years of relevant experience, or M.S. with 2+ years of relevant experience in Aerospace, Mechanical Engineering, Physics, or a related field
Extensive hands-on experience operating, maintaining, or improving high-vacuum chamber systems or high-voltage capacitor systems
Experience owning system uptime, reliability, and performance, including troubleshooting and root cause analysis
Proven experience executing complex experiments or operations with a focus on repeatability, safety, and continuous improvement
Demonstrated ability to rapidly learn new technologies and take ownership of operational systems
Strong problem-solving skills and ability to respond effectively to real-time issues with minimal supervision
Proven ability to collaborate effectively within a team and contribute to a high-performance operational environment
