Staff Process Engineer

What You'll Do

• Lead process engineering activities for key TOPCon unit processes, including tunnel oxide, polysilicon deposition, diffusion, passivation, and/or metallization
• Provide technical leadership and mentorship to process engineers supporting your assigned process areas
• Drive process stability and continuous improvement, using data to identify and close yield and efficiency gaps
• Establish and maintain process baselines, control plans, and process documentation for owned process steps
• Partner with Equipment, Metrology, and Quality teams to ensure process and tool readiness, control, and compliance
• Lead root cause analysis for yield excursions, efficiency losses, and cell performance deviations within your process area
• Support technology transfer and process qualification activities for new tools, materials, and process flows
• Collaborate with R&D and device engineering on next-generation process development and integration
• Represent your process area in cross-functional technical reviews and discussions

Who You Are

• A TOPCon practitioner - you know the technology well and have hands-on development and manufacturing experience to back it up
• A technical contributor who can operate effectively at both the bench and in cross-functional discussions
• Rigorous and methodical in your approach to process development, with a strong instinct for where problems are hiding
• Collaborative and effective across engineering disciplines, operations, and external partners
• Energized by the challenge of scaling advanced cell technology in a new fab environment

Qualifications

• MS or BS in Materials Science, Chemical Engineering, Electrical Engineering, Physics, or a related field
• 6+ years of process engineering experience in solar cell fabrication, with specific experience in TOPCon technology
• Solid understanding of TOPCon unit processes including tunnel oxide growth, polysilicon deposition, doping, and/or contact formation
• Hands-on experience with PECVD, LPCVD, diffusion furnaces, ALD, or related toolsets
• Working knowledge of process integration, yield analysis, and statistical process control
• Experience mentoring or providing technical guidance to junior engineers
• Exposure to technology transfer activities from development to high-volume production

The T1 Way

We’re all in on the mission, and we pursue it as one team. We move fast, own our results, and treat each other with respect. Egos stay at the door: no one is too senior to roll up their sleeves, and no idea is too small to share. Be sharp, be honest, be human. If you can hold the line and keep a sense of humor, you’ll fit right in.
