Nuclear Engineering Manager

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
