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: The computational research team at Helion works with multiple plasma simulation codes to simulate and analyze Helion’s fusion machines and test beds. The goal of the simulation effort is to develop predictive computational capabilities derived from first principles, validated against experimental data across multiple FRC merging devices, to inform next-generation fusion machine design. You Will: - Be responsible for using Helion’s computational suite of tools to study a particular aspect of the machine, which could include FRC formation, translation, merging, or compression - Work with your team and mentor to develop a simulation study and develop a set of results - Develop a report and present your findings to the broader research team at Helion Required Skills: - Ability to work full time, onsite in Everett, WA for a minimum of 12 consecutive weeks during summer 2027 - Currently pursuing a PhD in Physics, Aerospace Engineering, or a related field, with relevant experience in plasmas - Must be able to complete their PhD program and commence full-time employment no later than June 2028 - GPA of 3.0 or above - Experience working with plasma simulation codes (e.g. PIC, Vlasov codes, MHD) - Experience doing research in a team environment - Scripting and analysis in Python, C++ or MATLAB ## About Helion ## Company Overview - **One-liner**: Helion is building the world’s first fusion power plant to deliver clean, reliable, and affordable baseload electricity. - **Entity Type**: Private (Series G – $465M raised in 2026 at a $15.5B post-money valuation, led by Thrive Capital) - **Headquarters**: Everett, Washington, USA (with additional facilities in Chelan County, WA) - **Founded**: 2013 - **Founders**: David Kirtley (CEO), Anthony Pancotti, and others ## Core Business - **Primary industry**: Fusion energy generation (clean energy / climate tech) - **Target customers**: B2B – utilities, large-scale energy buyers (e.g., Microsoft, Nucor), and data center operators - **Mission**: Build the world’s first fusion power generators to provide clean, reliable, and affordable electricity for everyone. ## Products & Services - **Polaris**: The latest prototype fusion machine – a 19‑meter device with 50 MJ capacitor banks that demonstrated deuterium‑tritium fusion in early 2026. It is a pulsed, field‑reversed configuration (FRC) reactor designed to directly convert fusion energy into electricity (no steam turbine). - **Orion**: The planned first commercial fusion power plant, targeting 50 MW of electricity to Microsoft data centers by 2029. Modular, factory‑built generators that can be shipped to customers. - **HERCULES Program**: A $4M initiative funding 20 research institutions to develop enabling technologies for scaled fusion deployment. ## Market Standing - **Valuation**: $15.5 B (post‑money Series G, 2026) - **Key Metric**: Total funding raised – $465 M (Series G) plus prior rounds (undisclosed total). Annual revenue not applicable (pre‑revenue). - **Notable Investors/Partners**: Sam Altman (early backer, recently stepped off board), Thrive Capital (lead Series G), Microsoft (first PPA for fusion energy), Nucor (500 MW development deal) - **Growth Signals**: ~600 employees (up from 51‑200 in earlier years); Polaris achieved first privately‑developed DT fusion demonstration; signed first ever fusion power purchase agreement (Microsoft); expanding manufacturing capacity in Washington. ## Competitive Advantages - **Direct energy conversion**: Helion’s pulsed FRC design recovers electricity directly from the expanding plasma at >95% efficiency, skipping the inefficient steam cycle used by most fusion concepts. - **Pulsed approach**: The reactor pulses rapidly (sub‑second), producing fusion energy in bursts that can be synchronized to the grid, and uses solid‑state switches capable of hundreds of millions of pulses. - **Simpler magnets**: FRC plasma is self‑confining, requiring fewer and lower‑field magnets than tokamaks or stellarators, reducing cost and complexity. - **Fuel flexibility**: Uses deuterium and tritium (with tritium breeding planned) and ultimately can burn advanced fuels (D‑D, D‑He3) as the technology matures. ## Strategic Focus - **Commercial deployment**: Delivering 50 MW to Microsoft by 2029 (Orion plant); scaling up manufacturing to produce modular generators in factories. - **Technology maturation**: HERCULES program to solve tritium breeding, materials, and other enabling challenges; advancing Polaris toward net electricity generation. - **Partnership growth**: Expanding power purchase agreements and development deals with industrial and tech customers to meet surging demand (especially AI data centers). ## Why Work Here - **Culture**: “Urgency, rigor, ownership, and hard truths” – a mission‑driven environment focused on solving the hardest problems in fusion engineering. - **Work**: Hands‑on with real hardware (capacitors, magnets, plasma diagnostics) across mechanical, electrical, and physics disciplines. - **Location**: Based in the Pacific Northwest (Everett & Chelan County) with immediate access to skiing, hiking, and water sports. - **Benefits**: Premier medical/vision/dental (fully employer‑paid options), HSA contributions, wellness stipend, 5% 401(k) match, stock options, up to 12 weeks paid parental leave + 4 weeks for birthing parents, 21 vacation days, 10 sick days, 11 holidays + winter break. - **Hybrid/Remote**: Not explicitly stated; roles appear to be on‑site in Washington (given the hardware‑focused nature). - **Open Roles**: Engineers (mechanical, electrical, simulation, controls), magnet analysts, experimental scientists, technicians, machinists – over 100 positions listed. ## Sources 1.
