Our mission is to invigorate America with scalable, reliable, and low-cost energy. Our fully operational 5GW solar module facility in Wilmer, Texas, can manufacture more than 20,000 modules every 24 hours. By the time you finish reading this paragraph, we will have produced two solar panels that will power American homes and fuel domestic AI. We're focused on building advanced American manufacturing and we're passionate about engineering a better future filled with abundant energy.\nThe Role\nT1 Energy is looking to hire a Thermal Process Engineer to join our team supporting the process development and ramp of our G2 solar cell fab. This is a hands-on, high-impact role for a process engineer who knows their way around CVD toolsets and thermal systems and is ready to help build one of the most ambitious domestic solar manufacturing operations in the country.\nYou'll be working at the leading edge of solar cell fab, owning critical deposition and thermal processes that directly impact cell efficiency, yield, and throughput. If you've spent your career developing and optimizing PECVD, LPCVD, and thermal processes in a semiconductor or photovoltaic environment and you're ready to do it at scale, this is the role for you.\nWhat You'll Do\nDevelop, optimize, and own thermal and vapor deposition processes for solar cell fabrication, including PECVD and LPCVD toolsets.\n\nSupport process integration across the G2 solar cell fab, working closely with equipment, integration, and yield engineering teams.\n\nDrive process characterization, DOE execution, and data analysis to improve film quality, uniformity, and throughput.\n\nTroubleshoot process excursions and equipment issues on CVD and thermal tools, identifying root causes and implementing corrective actions.\n\nCollaborate with equipment engineers and tool vendors to qualify new tools, execute preventive maintenance reviews, and maintain process baselines.\n\nDevelop and maintain detailed process documentation, including recipes, SOPs, and control plans.\n\nMonitor process performance through statistical process control (SPC) and respond to out-of-control conditions with urgency.\n\nSupport technology transfer from development to high-volume manufacturing, ensuring processes are robust, repeatable, and scalable.\n\nPartner with cross-functional teams including device engineering, materials, and operations to meet cell efficiency and production targets.\n\nWho You Are\nDeeply knowledgeable in CVD processes - PECVD and LPCVD are your home turf.\n\nHands-on and comfortable getting into the details of both process and equipment to solve problems quickly.\n\nWell versed in thermodynamics, crystal lattice chemistry, principles of diffusion and chemical kinetics, and extreme prescience in quantum chemistry.\n\nData-driven in your approach to process development and troubleshooting - you let the numbers lead.\n\nAble to work effectively in a fast-moving fab environment where priorities shift and deadlines are real.\n\nA strong collaborator who can work across engineering disciplines and communicate technical findings clearly to varied audiences.\n\nEnergized by the challenge of building something new and scaling it to high-volume production.\n\nQualifications\nBachelor's degree or higher in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or a related field.\n\n5+ years of process engineering experience in semiconductor, photovoltaic, or advanced manufacturing environments.\n\nHands-on experience with PECVD and LPCVD toolsets is required.\n\nStrong working knowledge of vapor deposition processes and thermal tools and processes.\n\nExperience with process characterization, DOE methodology, and statistical process control (SPC).\n\nFamiliarity with solar cell fabrication processes and device physics is a strong plus.\n\nProficiency with data analysis tools (e.g., Python, JMP, Excel) for process monitoring and optimization.\n\nStrong documentation skills and experience writing SOPs, process specs, and engineering reports.\n\nAbility to support a fab environment, including occasional travel to the G2 facility as needed.\n\nThe T1 Way\nWe move fast, expect accountability, and treat people with respect. We also have a no-jerks policy: we don't tolerate big egos, bad behavior or \"that's not my job attitude\". Be sharp, be honest, be human. If you can hold the line and have a sense of humor, you'll fit right in.\nT1 Energy is an Equal Opportunity Employer. We are committed to creating an inclusive environment for all employees and applicants and do not discriminate on the basis of any legally protected characteristics.","description_format":"text","description_chars":4700,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy Storage","Solar Energy"],"lifecycle":[{"event":"open","at":"2026-09-10T22:46:28Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.432,"p_room":0.28,"age_days":155,"expected_fill_days":46,"reasons":["conf:0","stale_co","win:tail","crowd:"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/t1energy-senior-deposition-process-engineer","json_url":"https://alion.io/job/t1energy-senior-deposition-process-engineer.json","meta":{"generated_at":"2026-10-22T18:06:29Z","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":474,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":685344},"rest":"https://alion.io/mcp/rest/get_company?id=685344"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ft1energy-senior-deposition-process-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%2Ft1energy-senior-deposition-process-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%2Ft1energy-senior-deposition-process-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/t1energy-senior-deposition-process-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ft1energy-senior-deposition-process-engineer"}]}
