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 and 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). Now, we're turning up operations for Polaris, working towards delivering the world's first fusion power plant.
More than ever, it's a pivotal time to join us and have the opportunity to solve real challenges to create a better energy future. You will see first-hand how we value urgency, rigor, ownership, and hard truths, knowing it will take each to do what no one has before. Joining us, you will push the boundaries of what's possible and transform humanity for the better - because the world can't wait.
What You Will Be Doing:
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.
You will:
- 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
Required Skills:
- A professional understanding of radiation effects on materials, typically demonstrated by a degree in nuclear engineering, materials science, physics, or related discipline and 6+ years of hands-on work
- 4+ years of experience handling radioactive material
- 4+ years of experience working on non-aqueous corrosion and environmentally assisted degradation mechanisms (e.g., stress corrosion cracking, creep, accelerated fatigue)
- 4+ years of experience working on neutron interactions leading to e.g., material transmutation or helium bubble generation
- 4+ years of experience performing data analysis with a common coding language (Python, MATLAB, C++), data presentation, technical communication, and writing. Data presentation should include rigorous consideration of uncertainty and statistics
