Fusion Power EngineerWe 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 as well as new investors 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.You will play a critical role in supporting the core electrical energy management systems that power our fusion generators.
Our work spans pulsed power delivery to magnetics, power electronics and fusion energy recovery, low voltage controls and networking, and precision sensing in electrically noisy environments. We look for strong electrical engineers who bring deep expertise in a few areas and give them real ownership immediately. You'll focus on the areas where your strengths drive the most impact today, while gaining hands-on opportunities to grow into expanded scopes and solve system-level challenges.Focus Areas:High Voltage/Pulsed Power SystemsDesign, test, troubleshoot, support, and scale high-voltage systems for driving pulsed magnetic coils (1Evaluate and apply solid-state switching devices (IGBTs, MOSFETs, SCRs/thyristors) with attention to losses, protection, di/dt, dv/dt, and thermal performanceSpecify and integrate high energy components (capacitors, switches, pulse forming networks, buswork, protection, grounding)Power ElectronicsDesign, test, scale, and integrate DC/DC, AC/DC, DC/AC converters used for energy delivery, energy recovery, and distribution ranging from hundreds of volts to thousands of voltsDevelop switching-stage designs including half/full bridges, phase-shifted/full-bridge, LLC/series-resonant, or buck/boost-derived converters (topology selection based on efficiency, controllability, and fault behavior)Low Voltage Control and DiagnosticsDesign low voltage control electronics and PCBAs that interface with high energy systemsOwn schematic capture and support layout, help scale PCBA deliveries to tens of thousands of boardsBuild analog front ends for current/voltage/field/temp and other diagnostics: amplification, filtering, isolation, ADC interfacingEnsure measurement integrity in high EMI environments (noise mitigation, grounding, shielding, calibration strategies)Partner with firmware/software teams on acquisition requirements and data qualityRequired Skills:2+ years experience in power electronics, solving complex electrical engineering problems from design to deliveryBachelor's or Master's level degree in Electrical Engineering, Physics, or a related technical fieldDemonstrated strength in at least one of the focus areas aboveHands-on troubleshooting ability with standard lab equipment (oscilloscope, DMM, power supplies, loads, function/pulse generators, etc)Comfortable working in high-energy or electrically noisy environments with strong safety mindset and disciplined documentationExperience with Microsoft Suite, LTSpice, SIMetrix/SIMPLIS, Simulink, Python, and/or MATLABOur total compensation package includes benefits, including but not limited to:Medical, Dental, and Vision plans for employees and their families31 Days of PTO (21 vacation days and 10 sick days)10 Paid holidays, plus company-wide winter breakUp to 5% employer 401(k) matchShort term disability, long term disability, and life insurancePaid parental leave and support (up to 16 weeks)Annual wellness stipendHelion is an equal opportunity employer and value diversity at our company.
