Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win.\nAbout the Role\nAs a Nuclear Engineer at Fuse, you'll bring expertise in particle transport, Monte Carlo simulation, radiation shielding, and radiation diagnostics to our fusion facility.\nYou'll develop and implement radiation diagnostics for facility operations and experimental characterization and work closely with physicists and engineers to advance our diagnostic capabilities.\nCore Responsibilities\nImplement and optimize neutron and gamma diagnostic systems for radiation characterization in fusion experiments and conduct experimental validation of neutron and gamma detection systems.\nAnalyze radiation data to support experimental campaigns, including source characterization, spectral unfolding, and spatial/temporal diagnostics.\nPerform radiation-transport analysis to improve system performance and safety.\nDevelop and maintain radiation test environments for detector calibration and material testing.\nDevelop and apply Monte Carlo simulations such as MCNP, Geant4, or FLUKA for particle transport, shielding, dose assessment, and detector performance.\nDesign and optimize radiation shielding for mixed neutron and gamma environments.\nSupport meteorological assessments related to radiation dispersion and environmental safety.\nAnalyze radiation data for operational safety, shielding effectiveness, and compliance with regulatory requirements.\nCollaborate with multidisciplinary teams on fusion technology development and radiation-safety initiatives.\nMinimum Qualifications\nMaster's or PhD in Nuclear Engineering, Physics, or a related field.\nStrong experience in Monte Carlo particle-transport simulations using MCNP, Geant4, FLUKA, or similar tools.\nHands-on experience with neutron and gamma detection techniques.\nKnowledge of radiation shielding, dose calculations, and safety assessments.\nExperience in radiation metrology and calibration techniques.\nProficiency in data analysis and programming using Python, MATLAB, C++, or similar tools.\nFamiliarity with regulatory frameworks including CNSC, NRC, and IAEA standards.\nPreferred Qualifications\nExperience working in fusion/fission facilities or similar combined neutron-gamma radiation environments.\nBackground in high-energy neutron/gamma transport and shielding.\nKnowledge of advanced radiation-detection technologies.\nWhat We Value\nGive a shit. Build things you're proud of.\nTake responsibility. If something is broken and you can fix it, fix it. See things through.\nMove fast. Make decisions, learn quickly, and keep moving forward.\nThink bigger. Simplify relentlessly. Don't default to the safe answer.\nDisagree and commit. The best idea wins. Once a decision is made, we move.\nDesire to win. This is hard. Expect intensity. We are here to win.\nPlan B is to make Plan A work.\nAdditional Requirements\nMust be able to travel and work extended hours/weekends as needed.\nSecurity Clearance\nThis role may require the ability to obtain and maintain a U.S. government security clearance.\nSecurity Clearance\nThis role may require the ability to obtain and maintain a U.S. government security clearance.\nBenefits\nMedical, dental, and vision coverage.\nRelocation assistance for roles that require it.\nFlexible time off. Take what you need, no accrual tracking.\n2 weeks of paid time off built into the end of each year, subject to team and business needs.\nSupportive leave of absence policies.\nPaid leave for new parents.\nITAR Requirements\nTo conform to U.S. Government technology export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.\nEqual Opportunity\nFuse is an Equal Opportunity Employer; employment with Fuse is governed on the basis of merit, competence, and qualifications and will not be influenced by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, ancestry, immigration status, sexual orientation, gender identity, marital status, mental or physical disability, or any other legally protected status.","description_format":"text","description_chars":4458,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":["Flexible time off","Relocation assistance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Nuclear Energy"],"lifecycle":[{"event":"open","at":"2026-09-13T05:41:29Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.255,"p_room":0.28,"age_days":69,"expected_fill_days":30,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/f-nuclear-engineer","json_url":"https://alion.io/job/f-nuclear-engineer.json","meta":{"generated_at":"2026-10-29T00:31:09Z","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":636,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":691631},"rest":"https://alion.io/mcp/rest/get_company?id=691631"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ff-nuclear-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%2Ff-nuclear-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%2Ff-nuclear-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/f-nuclear-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ff-nuclear-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":854630}},{"tool":"search_jobs","arguments":{"company":"f.energy","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":854630},"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); https://alion.io/mcp with an Alion account has everything.
