The RoleT1 Energy is looking to hire a Process Manager to lead process engineering at our G2 solar cell fab in Rockdale, Texas. This is a senior technical leadership role for someone with deep, hands-on expertise in TOPCon cell technology and the experience to translate that knowledge into a high-performing, high-yield production environment.
You've developed and scaled TOPCon processes before. You understand the science, you know the toolsets, and you've seen what it takes to move from development to high-volume manufacturing without losing efficiency or cell performance. Now you'll own it from the top.
What You'll Do- Own all process engineering activities at the G2 solar cell fab, with direct responsibility for TOPCon cell process development, integration, and optimization.
- Lead a team of process engineers across key unit processes including tunnel oxide, polysilicon deposition, diffusion, passivation, and metallization.
- Drive process stability and continuous improvement across the fab, using data to identify and close yield and efficiency gaps.
- Establish and maintain process baselines, control plans, and process documentation across all cell fab process steps.
- Partner with Equipment, Metrology, and Quality teams to ensure process and tool readiness, control, and compliance.
- Lead process-related root cause analysis for yield excursions, efficiency losses, and cell performance deviations.
- 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 process engineering in cross-functional leadership reviews and external technical discussions.
Who You Are- A TOPCon expert - you know the technology deeply and have the development and manufacturing experience to back it up.
- A technical leader who can operate at both the bench and the boardroom level.
- 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- PhD or MS in Materials Science, Chemical Engineering, Electrical Engineering, Physics, or a related field.
- 10+ years of process engineering experience in solar cell fabrication, with specific and demonstrated expertise in TOPCon technology.
- Deep understanding of TOPCon unit processes including tunnel oxide growth, polysilicon deposition, doping, and contact formation.
- Hands-on experience with PECVD, LPCVD, diffusion furnaces, ALD, and related toolsets.
- Strong background in process integration, yield analysis, and statistical process control.
- Experience managing or leading process engineering teams in a high-volume manufacturing environment.
- Track record of supporting technology transfer 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.
