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:\nAs a Mechanical Engineering Intern at Helion you'll be at the forefront of fusion technology development. Helion internships are designed to give real ownership to help train the next generation of fusion engineers. You'll collaborate on R&D efforts, explore potential system upgrades to enhance overall performance, and contribute fresh ideas as we work on next-generation machines. This internship will require solving engineering problems critical to deploying fusion energy to the world. This is a 12-week onsite internship at our Everett, WA office.\nYou Will:\nOwn and understand designs across subsystems in fields including electromagnetics, structures, fluids, thermal, and control systems\n\nLearn from historical engineering approaches, design novel hardware, and test your solutions\n\nFix hardware issues as they arise on integrated fusion generators\n\nApply both engineering first-principles and method-based thinking to challenging problems\n\nLearn from experts to expand your engineering skillset and domain knowledge\n\nRequired Skills:\nAbility to work full time, onsite in Everett, WA for a minimum of 12 consecutive weeks during summer 2027\n\nGraduation date of Winter 2027 or Spring 2028\n\nCurrently enrolled in a Bachelor’s degree in Mechanical Engineering or related field\n\nGPA of 3.0 or above\n\nHands-on exposure to a variety of engineering disciplines (e.g. mechanical, electrical, fluids)\n\nExperience with 3D CAD software (e.g. NX, SolidWorks) and GD&T\n\n#LI-Onsite #LI-KL1","description_format":"text","description_chars":2558,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Nuclear Energy","Nuclear Engineering"],"lifecycle":[{"event":"open","at":"2026-09-30T05:49:55Z"},{"event":"close","at":"2026-10-19T23:24:47Z"}],"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":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":null,"pay":{"stated_usd_annual":96000,"is_top_pay":true},"html_url":"https://alion.io/job/helion-energy-mechanical-engineering-summer-2027-intern","json_url":"https://alion.io/job/helion-energy-mechanical-engineering-summer-2027-intern.json","meta":{"generated_at":"2026-11-06T02:54:40Z","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":4947,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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%2Fhelion-energy-mechanical-engineering-summer-2027-intern"},{"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%2Fhelion-energy-mechanical-engineering-summer-2027-intern"},{"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%2Fhelion-energy-mechanical-engineering-summer-2027-intern"},{"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/helion-energy-mechanical-engineering-summer-2027-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhelion-energy-mechanical-engineering-summer-2027-intern"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1506065}},{"tool":"search_jobs","arguments":{"company":"helionenergy.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1506065},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
