Senior Thermal Diffusion Engineer – High-Volume Solar

T1 Energy; Austin (TX); Sur place; USD 110 000 - 140 000; Plein temps

Résumé du poste

T1 Energy in Wilmer, Texas is seeking a Thermal Process Engineer to join our fast-moving team supporting the ramp of our G2 solar cell fab. You will own critical diffusion and thermal processes that affect cell efficiency, yield, and throughput in a high-volume manufacturing setting.

The role offers hands-on work in a clean room environment, close collaboration with equipment engineers and procurement, and opportunities to transfer processes from development to production at scale.

Qualifications

• Bachelor's degree or higher in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or related field.
• 5+ years of process engineering experience in semiconductor, photovoltaic, or advanced manufacturing environments.
• Hands-on experience with high temperature diffusion toolsets.
• Strong working knowledge of ion implantation processes and diffusion thermal tools.
• Experience with DOE methodologies, statistical process control (SPC), micron-level physical inspection and optical/electrical characterization.
• Proficiency with Python, SQL, JMP, and Excel for process monitoring and optimization.
• Ability to support a fab environment, including occasional travel to the G2 facility as needed.

Responsabilités

• Support thermal doping process integration across the G2 solar cell fab, working closely with equipment, facility, quality, and yield engineering teams.
• Drive process characterization, DOE execution, and data analysis to improve dopant uniformities and throughput.
• Troubleshoot process excursions and equipment issues on diffusion tools and sub-inspection modules, identifying root causes and implementing corrective actions.
• Collaborate with equipment engineers and tool vendors to qualify new tool integrations, execute preventive maintenance reviews, and maintain process baselines.
• Develop and maintain detailed process documentation, including recipes, SOPs, and control plans.
• Optimize process performance through statistical process control (SPC) and lead OEM work inspection development integration with urgency.
• Support technology transfer from development to high-volume manufacturing, ensuring processes are robust, repeatable, and scalable.
• Partner with cross-functional teams including core equipment engineering, material procurement, and manufacturing operations to meet cell efficiency and production targets.
