This role will focus on designing, prototyping, and experimentally validating high-performance cooling architectures, with particular emphasis on jet impingement, spray and microjet technologies, and high heat-flux heat transfer. You will work hands-on from early concepts and modeling through prototype fabrication, testing, and integration with SCD-based semiconductor systems.\nResponsibilities\nLead the design and development of high-performance liquid cooling architectures for SCD-based semiconductor thermal management, including jet impingement, spray, and microjet-based concepts.\n\nModel and optimize fluid flow and heat transfer to define jet/nozzle geometries, flow distribution, pressure, temperature, and operating conditions, including single- and two-phase heat transfer regimes.\n\nDesign cooling hardware for prototyping and manufacturing, incorporating fluid distribution, extraction/return paths, and micro-machined features while considering practical fabrication constraints.\n\nBuild and experimentally characterize prototypes, analyzing thermal and fluid performance and using test results to iterate and improve designs.\n\nDrive the technical development from initial concept through prototype demonstration and integration with SCD-based semiconductor devices, collaborating with internal engineering and manufacturing teams and external research or fabrication partners as needed.\n\nRequirements\nDegree in Mechanical Engineering, Thermal Engineering, Fluid Mechanics, or a related field; an MSc or PhD is highly valued, particularly when combined with applied R&D and prototype development experience.\n\nStrong background in thermal engineering, fluid dynamics, and heat transfer, with experience developing high-performance liquid cooling systems or devices. Experience with Ansys or COMSOL is a plus\n\nHands-on experience designing and validating thermal-fluid hardware, with exposure to technologies such as jet impingement, spray cooling, microjets/microfluidics, or other high heat-flux cooling approaches.\n\nExperience with computational and/or analytical thermal-fluid modeling, ideally including CFD, combined with experimental testing and validation.\n\nExperience designing components for precision or micro-scale manufacturing processes, such as micromachining, and translating engineering concepts into manufacturable prototypes.","description_format":"text","description_chars":2634,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Advanced Materials","Jewelry","Semiconductor Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-16T12:34:29Z"}],"visa":[],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.901,"p_room":0.75,"age_days":56,"expected_fill_days":71,"reasons":["conf:2","velocity","win:late"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/diamond-foundry-senior-thermal-fluids-engineer-advanced-cooling","json_url":"https://alion.io/job/diamond-foundry-senior-thermal-fluids-engineer-advanced-cooling.json","meta":{"generated_at":"2026-11-12T11:51:48Z","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":24441,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"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":14996},"rest":"https://alion.io/mcp/rest/get_company?id=14996"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdiamond-foundry-senior-thermal-fluids-engineer-advanced-cooling"},{"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%2Fdiamond-foundry-senior-thermal-fluids-engineer-advanced-cooling"},{"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%2Fdiamond-foundry-senior-thermal-fluids-engineer-advanced-cooling"},{"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/diamond-foundry-senior-thermal-fluids-engineer-advanced-cooling\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdiamond-foundry-senior-thermal-fluids-engineer-advanced-cooling"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":963716}},{"tool":"search_jobs","arguments":{"company":"df.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":963716},"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.
