Our core mandate is to systematically retire technical risks for HTS Cable Magnets by developing experiments, prototypes, and specialized test stands, followed by rigorous testing to generate high-quality data. Strong foundational knowledge in physics, mechanical engineering, electrical systems, materials science, fluid dynamics, and finite element analysis (FEA) is essential. We are privileged with a high degree of cownership of the risks assigned to us, from initial concept to final validation:\nStakeholder Collaboration & Consensus: Partner across R&D, Design, Manufacturing, and Procurement to critically evaluate requirements, clarify test objectives, and align stakeholders on necessary outcomes and essential data\nDesign & Build: Engineer and construct targeted hardware, prototypes, and custom test systemsrequired to fulfill objective goals\n\nTesting & Commissioning: Commission setups, run experiments safely and methodically\n Sharing the results: Perform rigorous data analysis, and communicate results clearly to the broader organization. Ultimately our output is data and it is our responsibility to stand by it\nWhat you'll do:\nDesign, analyze, review, procure, and build mechanical assemblies and test equipment. Including structures, fluid systems, pressure vessels, mechanical systems, and electro-mechanical systems. We deal with extreme environments and conditions: tens of tons of load, thousands of amps, kilovolts, cryogenic temperatures etc\nWork with Test Engineers to plan tests for achieving objectives, collecting key data needed and defining instrumentation and controls necessary to obtain this data. Ensure data is reliable and validated \nUnderstand, challenge, and maintain well-documented requirements and risks for the system or component under test\nIdentify and mitigate safety hazards associated with test equipment and prototypes. Produce safety documentation such as job hazard assessments and test readiness reviews\nMaintain documentation and schedule for projects responsible for. Documentation may include: design reviews, wiring lists, P&IDs, schematics, CAD assemblies, and drawings, and technician work instructions\nPerform any needed analysis to create successful designs. Analysis may include structural, thermal, or fluid.\nAnalysis to include first principles hand calculations and/or FEA, whichever is warranted.\nTroubleshoot and resolve integration discrepancies during build, and commissioning of new designs\nIterate on designs, equipment, and operations to improve designs\nWhat we’re looking for:\nBachelors degree in engineering or science field is required; Mechanical engineering or similar, or applied physics degree\n3+ years experience designing, analyzing, fabricating, and commissioning complex mechanical and electro-mechanical assemblies\n3+ years using CAD software to design complex assemblies, producing drawings for procurement with a working knowledge of GD&T and tolerance stack-up\n3+ years experience with analysis of mechanical components, strength of materials and failure criteria. Familiar with use of fasteners, analysis of welds, and bolted joints\nFamiliarity with electromagnetic fundamentals - voltage, current, resistance, Ohm’s Law, AC/DC, right-hand rule, solenoids, etc\nExcellent troubleshooting/problem- solving skills with great attention to detail\nEffective at communicating technical topics to both technical and non-technical audiences\nHigh self-motivation and drive to execute quickly\nA can-do attitude and an eagerness to learn and/or teach junior engineers/technicians\nCollaboration skills including active listening and facilitating a productive discourse on problems\nAbility to innovate creative solutions to challenging problems\nWillingness to challenge the status quo in search of better, more efficient methods\nBonus points for:\n5+ years experience designing, analyzing, fabricating, and commissioning complex mechanical and electro-mechanical assemblies\n5+ years using CAD software to design complex assemblies, producing drawings for procurement with a working knowledge of GD&T and tolerance stack-up\n5+ years experience with analysis of mechanical components, strength of materials and failure criteria. Familiar with use of fasteners, analysis of welds, and bolted joints\nExperience with structural FEA software, especially ANSYS and COMSOL\nExperience with multi-physics analysis in ANSYS or COMSOL\nExperience using NX and Teamcenter\nExperience with high field magnet testing, traditional or superconducting\nExperience with data processing, analysis, and plotting using Python, MATLAB, or similar\nExperience with high voltage and high current power equipment design and use - power supplies, water cooled cables, insulation\nMust-have requirements:\nAbility to occasionally lift up to 50 lbs\nPerform activities such as typing, climbing, standing, stooping or sitting for extended periods of time\nWillingness to occasionally travel or work required nights/weekends/on-call\nWork in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics","description_format":"text","description_chars":5388,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Nuclear Energy","Nuclear Engineering"],"lifecycle":[{"event":"open","at":"2026-11-13T00:32:33Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":50,"reasons":["conf:0","velocity","win:early","comp:brand"],"computed_at":"2026-11-15T07:52:55Z"},"pay":{"stated_usd_annual":160000,"is_top_pay":true},"html_url":"https://alion.io/job/commonwealth-fusion-systems-rd-engineer","json_url":"https://alion.io/job/commonwealth-fusion-systems-rd-engineer.json","meta":{"generated_at":"2026-11-15T18:23:08Z","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":11214,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-16T00:00:00Z"}},"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":8705},"rest":"https://alion.io/mcp/rest/get_company?id=8705"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcommonwealth-fusion-systems-rd-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fcommonwealth-fusion-systems-rd-engineer"},{"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%2Fcommonwealth-fusion-systems-rd-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/commonwealth-fusion-systems-rd-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcommonwealth-fusion-systems-rd-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4209587}},{"tool":"search_jobs","arguments":{"company":"cfs.energy","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4209587},"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.
