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 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:
You will lead Helion’s Nuclear Engineering team, which includes subject matter experts in neutronics, nuclear diagnostics, and general nuclear engineering. You will be responsible for setting direction, driving execution, and building team capabilities to meet the nuclear engineering needs of Helion’s fusion systems. You will report to the Director of the Radiation Safety and Nuclear Science (RaSNS) team, and this is an onsite role located at our Everett, WA office.
You Will:
- Manage, develop, and support nuclear engineering experts responsible for quantifying fusion yield and simulating radiation environments using neutronics simulation codes
- Own the delivery of shielding design, activation analysis, dose estimation, and nuclear diagnostic development
- Oversee team performance and conduct hiring activities to expand the team as project scope grows
- Translate annual goals into actionable tasks and manage month-to-month planning to achieve objectives
- Drive schedule ownership across the team to accelerate milestone completion
Required Skills:
- 3+ years of experience managing a nuclear-engineering-focused technical team delivering high-impact work, expanding the team through hiring, and owning schedules for critical-path projects
- Experience performing neutronics simulations using MCNP, including implementing variance reduction techniques and simulation-measurement verification for moderately complex geometries
- Hands-on experience handling radioactive materials such as neutron sources (e.g., Cf-252, AmBe, neutron generators) and operating diagnostic detectors (e.g., scintillators, He-3, activation foils)
- Demonstrated ability to mentor and manage employees of varying expertise and backgrounds, including performance reviews and coaching
- Proficiency with people management systems (e.g., recruiting, timecard management, spend approval, and performance evaluations) and applying internal policies
