Job description

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.
What You Will Be Doing:
You will lead the Nuclear Engineering team that comprises neutronics, nuclear diagnostics and general nuclear engineering. You will report to the Director of Plasma and Nuclear Science team in this onsite role located at our Everett, WA office.
You Will:
  • Manage, develop, and assist the subject matter experts responsible for quantifying fusion yield via nuclear diagnostics and simulating radiation environments using neutronics simulation codes
  • Own and manage the delivery of Helion's nuclear engineering needs such as shielding design, activation analysis, dose estimation, and diagnostic development
  • Manage the performance of nuclear engineers and conduct hiring actions to build the team as scope demands
  • Translate annual goals into objective tasks and manage month-to-month planning towards completing goals and objectives
  • Drive schedule ownership to accelerate the completion of milestones

Required Skills:
  • 3+ years of experience managing a nuclear-engineering-related technical team that delivered a high-impact final product, expanding a talent-dense team via a hiring process and owning the schedule for a critical path facet of a milestone project
  • Experience performing neutronics simulations using MCNP as demonstrated via implementing variance reduction techniques and performing simulation-measurement verification for moderately complex geometries
  • Hands-on experience handling radioactive material including neutron sources (e.g., Cf-252, AmBe, neutron generators), and experience operating diagnostic detectors (e.g., scintillators, He-3, activation foils)
  • Successful and autonomous mentorship of employees of a wide range of expertise, experience, and backgrounds, demonstrated e.g., via several performance review cycles and successful coaching of direct reports
  • Fluent in some people management systems (e.g., recruiting, timecard management, spend approval, and performance reviews) and applying company policies as described in an employee handbook

Benefits
Our total compensation package includes benefits, including but not limited to:
  • 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
  • Up to 5% employer 401(k) match
  • Short term disability, long term disability, and life insurance
  • Paid parental leave and support (up to 16 weeks)
  • Annual wellness stipend

Helion is an equal opportunity employer and value diversity at our company. We do not discriminate based on race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. If you need assistance or an accommodation during the interview process, please let us know.
