Our vision is a world with clean, reliable, and affordable energy for everyone.\nSince 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.\nThis 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.\nWhat You Will Be Doing:\nYou 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.\nWe 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.\nFocus Areas:\nHigh Voltage/Pulsed Power Systems\nDesign, test, troubleshoot, support, and scale high-voltage systems for driving pulsed magnetic coils (1\n\nEvaluate and apply solid-state switching devices (IGBTs, MOSFETs, SCRs/thyristors) with attention to losses, protection, di/dt, dv/dt, and thermal performance\n\nSpecify and integrate high energy components (capacitors, switches, pulse forming networks, buswork, protection, grounding)\n\nPower Electronics\nDesign, 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 volts\n\nDevelop 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)\n\nLow Voltage Control and Diagnostics\nDesign low voltage control electronics and PCBAs that interface with high energy systems\n\nOwn schematic capture and support layout, help scale PCBA deliveries to tens of thousands of boards\n\nBuild analog front ends for current/voltage/field/temp and other diagnostics: amplification, filtering, isolation, ADC interfacing\n\nEnsure measurement integrity in high EMI environments (noise mitigation, grounding, shielding, calibration strategies)\n\nPartner with firmware/software teams on acquisition requirements and data quality\n\nRequired Skills:\n2+ years experience in power electronics, solving complex electrical engineering problems from design to delivery\n\nBachelor’s or Master’s level degree in Electrical Engineering, Physics, or a related technical field\n\nDemonstrated strength in at least one of the focus areas above\n\nHands-on troubleshooting ability with standard lab equipment (oscilloscope, DMM, power supplies, loads, function/pulse generators, etc)\n\nComfortable working in high-energy or electrically noisy environments with strong safety mindset and disciplined documentation\n\nExperience with Microsoft Suite, LTSpice, SIMetrix/SIMPLIS, Simulink, Python, and/or MATLAB\n\nBenefits\nOur total compensation package includes benefits, including but not limited to:\nMedical, Dental, and Vision plans for employees and their families\n\n31 Days of PTO (21 vacation days and 10 sick days)\n\n10 Paid holidays, plus company-wide winter break\n\nUp to 5% employer 401(k) match\n\nShort term disability, long term disability, and life insurance\n\nPaid parental leave and support (up to 16 weeks)\n\nAnnual wellness stipend\n\nHelion is an equal opportunity employer and value diversity at our company. We do not discriminate based on race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. If you need assistance or an accommodation during the interview process, please let us know.","description_format":"text","description_chars":4522,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Life insurance","Parental leave"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Nuclear Energy","Nuclear Engineering"],"lifecycle":[{"event":"open","at":"2026-02-26T19:33:52Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":177500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.479,"p_room":0.28,"age_days":231,"expected_fill_days":99,"reasons":["conf:1","win:tail","crowd:junior"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/helionenergy-electrical-engineer","json_url":"https://alion.io/job/helionenergy-electrical-engineer.json","meta":{"generated_at":"2026-10-16T23:10:10Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":5028,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":10265},"rest":"https://alion.io/mcp/rest/get_company?id=10265"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhelionenergy-electrical-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fhelionenergy-electrical-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fhelionenergy-electrical-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/helionenergy-electrical-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhelionenergy-electrical-engineer"}]}
