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 $600 million from investors such as Sam Altman, Mithril, and Capricorn Investment Group 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).
Now we are working toward Polaris, which will be the first machine to demonstrate electricity from fusion, making this a great time to join Helion! Bring your skills, experiences, and determination to make a difference in the world. Together, we can make a future with unlimited clean electricity from fusion a reality.
You will help Helion develop designs and materials suitable for high radiation environments by analyzing and advising engineers on radiation effects on a range of materials. You will report to our Director of Materials at our Everett, WA office.
-
Advise engineering design decisions based on radiation effects (due to neutrons and photons) on materials used within the radiation shield vault, e.g., metals used in magnet coils, dielectrics used for structure, and polymers used for cable jacketing
-
Partner with neutronics engineers to predict dpa, analyze, model, and predict macroscopic effects on material properties including thermal conductivity, electrical resistivity, and mechanical strength. Assess system-level radiation risk
-
Perform literature reviews on radiation effects on materials of interest and distill the information into summaries for non-nuclear engineers, reactively. Maintain a database of radiation effects on materials
-
Operate in an environment with obstacles and changing requirements
-
Partner with other internal Helion teams, external vendors, national laboratories, and universities to gather the required capabilities. Develop your network and represent Helion at technical meetings and conferences
-
A degree in nuclear engineering, radiological sciences, materials science/engineering, chemistry/chemical engineering, or a related technical discipline, and the ability to apply experience working on radiation effects to a range of materials
-
Knowledge of non-aqueous corrosion and environmentally assisted degradation mechanisms (e.g., stress corrosion cracking, creep, accelerated fatigue); broad understanding of materials science and engineering; and an understanding of typical neutron and photon interactions (e.g., leading to material transmutation or helium bubble generation)
-
Data analysis with a common coding language (Python, MATLAB, C++), data presentation, technical communication, and writing

- 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
NOTE: Underrepresented people are less likely to apply unless they meet 100% of the job’s requirements. We believe in hiring people, not checklists, and encourage you to apply even if you do not check all of the boxes. If this job isn’t the one, we have many other openings that may be a fit.
All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, disability, age, sexual orientation, gender identity, national origin, veteran status, or genetic information. If we reach out to you to begin an interview process, we will also ask if you require any reasonable accommodation at that time.
