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\nFuse is the first private company building a fusion facility based on Magnetized Liner Inertial Fusion (MagLIF), an approach proven through a decade of simulation and experiments at Sandia National Laboratories. Our work spans Impedance Matched Marx Generator (IMG) drivers, MagLIF and the broader high-energy-density physics (HEDP) that governs how our machines compress and heat fusion fuel. We are building an in-house computational physics capability to model that physics end to end, from the pulsed-power driver to the imploding load to the fusion burn. As a Computational Plasma Physicist, you will develop and apply PIC and MHD simulations of MagLIF, Z-pinch and HEDP experiments, working shoulder to shoulder with our experimental, pulsed-power and target teams to interpret what we measure and design what we build next. This is a high-ownership role with direct influence on our experimental program and machine design.\nWHAT WE VALUE\nObsess about the details - sloppy work costs us later, so do it right the first time.\n\nCare - pick up the trash. Do things no one asks you to do. Go the extra mile because you care.\n\nAct with urgency - every hour matters more than it feels like it does.\n\nBe responsible for the outcome, not just the task; if it is not working, it remains your problem until it is fixed.\n\nAssume good intent - disagree openly, then commit fully once a call is made.\n\nCORE RESPONSIBILITIES\nRun and analyze hybrid, PIC and MHD simulations of MagLIF, liner, wire-array and Z-pinch implosions, and of the HEDP conditions they produce.\n\nDevelop, extend and optimize simulation codes to improve physical fidelity, numerical accuracy and computational efficiency.\n\nTranslate simulation output into physical insight that guides real decisions: implosion dynamics, instability growth, magnetic flux compression, preheat and fusion yield.\n\nPartner with experimentalists to design campaigns and interpret results, closing the loop between simulation and measurement.\n\nModel the full chain where relevant, from pulsed-power driver through load to burn, with the driver and target teams.\n\nDocument and share results through internal reports, peer-reviewed publications and conference presentations.\n\nMINIMUM QUALIFICATIONS\nPh.D. in Physics, Plasma Physics, Computational Science or a related field.\n\nStrong foundation in plasma physics and HEDP, with direct experience in MHD and/or PIC modeling of liner, wire-array or pinch implosions.\n\nHands-on experience with high-performance computing and parallel programming.\n\nProficiency in scientific programming in Fortran, C++ and Python.\n\nA track record of rigorous, well-communicated research and strong collaboration across a multidisciplinary team.\n\nPREFERRED QUALIFICATIONS\nDirect experience with MagLIF or other HEDP / ICF experiments.\n\nFamiliarity with simulation tools such as LSP, CHICAGO, HYDRA, FLASH, GORGON, MACH2 or comparable radiation-MHD / PIC codes.\n\nExperience coupling pulsed-power circuit models to load simulations.\n\nBackground in instability analysis (MRT, electrothermal), magnetized transport, or equation-of-state / opacity modeling.\n\nStrong peer-reviewed publication record.\n\nADDITIONAL REQUIREMENTS\nThis is not a remote position and will require relocation if not already local to Fuse's San Leandro, CA facility.\n\nOccasional travel to other Fuse locations and partner facilities.\n\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":4777,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","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":"2026-11-10T03:23:29Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.602,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:3","stale_co","win:early"],"computed_at":"2026-11-10T06:52:35Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/fuse-computational-plasma-physicist","json_url":"https://alion.io/job/fuse-computational-plasma-physicist.json","meta":{"generated_at":"2026-11-10T17:30:37Z","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":6263,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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%2Ffuse-computational-plasma-physicist"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Ffuse-computational-plasma-physicist"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Ffuse-computational-plasma-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/fuse-computational-plasma-physicist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffuse-computational-plasma-physicist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4000915}},{"tool":"search_jobs","arguments":{"company":"f.energy","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4000915},"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.
