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 Computational Physicist at Fuse, you'll develop the models and simulations that explore how our pulsed-power systems actually behave - turning physics, mathematics, and computational methods into predictions the team can build on.\nCore Responsibilities\nDevelop and run simulations for pulsed-power systems using MHD, PIC, and circuit models.\n\nUtilize and modify Screamer circuit code for modeling high-voltage pulse generation and delivery.\n\nConduct magnetohydrodynamic (MHD) simulations to study plasma dynamics in fusion and Z-pinch configurations.\n\nImplement and analyze particle-in-cell (PIC) simulations for plasma interactions and beam dynamics.\n\nModel impedance matching in Marx generators and analyze energy coupling in plasma loads.\n\nCollaborate with experimentalists to validate models and optimize system performance.\n\nDevelop custom computational tools and optimize existing codes for high-performance computing (HPC).\n\nAnalyze and interpret large data sets, extracting meaningful insights and presenting findings in clear, concise reports.\n\nDevelop software tools and algorithms to optimize simulation processes and improve computational efficiency.\n\nStay up to date with advancements in computational techniques, programming languages, and physical theories to apply state-of-the-art methodologies to projects.\n\nContribute to academic papers, technical reports, and presentations, sharing results with both internal teams and external collaborators.\n\nProvide technical mentorship and guidance to junior team members.\n\nMinimum Qualifications\nPh.D. or M.S. in Physics, Electrical Engineering, Applied Mathematics, or a related field.\n\nStrong background in computational plasma physics and high-energy-density physics.\n\nExperience with Screamer, MAGIC, HYDRA, or similar circuit and plasma codes.\n\nProficiency in MHD and PIC simulation techniques.\n\nStrong programming skills in Python, Fortran, C++, or MATLAB for numerical modeling.\n\nExperience with HPC environments and parallel computing.\n\nStrong foundation in theoretical physics, including electromagnetism, classical mechanics, statistical mechanics, or related areas.\n\nStrong problem-solving abilities, analytical skills, and attention to detail.\n\nAbility to present complex results to technical and non-technical audiences.\n\nPreferred Qualifications\nFamiliarity with Z-pinch, MagLIF, dense plasma focus devices, and fusion energy concepts.\n\nExperience in finite element analysis (FEA) or finite difference time domain (FDTD) methods.\n\nKnowledge of electromagnetic wave propagation and plasma-material interactions.\n\nExperience working in experimental plasma physics or fusion research.\n\nStrong publication record in computational physics or related fields.\n\nBackground in developing custom software tools for physical simulations.\n\nFamiliarity with version control tools and collaborative software-development practices.\n\nPrior experience publishing research or contributing to academic journals and conferences.\n\nWhat We Value\nGive a shit. Build things you're proud of.\n\nTake responsibility. If something is broken and you can fix it, fix it. See things through.\n\nMove fast. Make decisions, learn quickly, and keep moving forward.\n\nThink bigger. Simplify relentlessly. Don't default to the safe answer.\n\nDisagree and commit. The best idea wins. Once a decision is made, we move.\n\nDesire to win. This is hard. Expect intensity. We are here to win.\n\nPlan B is to make Plan A work.\n\nAdditional Requirements\nThis is not a remote position and will require relocation if not already local to the applicable Fuse facility.\nBenefits\nMedical, dental, and vision coverage.\n\nRelocation assistance for roles that require it.\n\nFlexible time off. Take what you need, no accrual tracking.\n\n2 weeks of paid time off built into the end of each year, subject to team and business needs.\n\nSupportive leave of absence policies.\n\nPaid leave for new parents.\n\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":4997,"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":0.26,"p_room":0.28,"age_days":77,"expected_fill_days":30,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-11-04T06:34:25Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/f-computational-physicist","json_url":"https://alion.io/job/f-computational-physicist.json","meta":{"generated_at":"2026-11-04T11:27:14Z","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":16981,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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-computational-physicist"},{"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-computational-physicist"},{"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-computational-physicist"},{"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-computational-physicist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ff-computational-physicist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":854649}},{"tool":"search_jobs","arguments":{"company":"f.energy","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":854649},"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.
