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 WayWe 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.
