Senior Deposition Process Engineer

The role

This person will develop, optimize, and own thermal and vapor deposition processes for solar cell fabrication. They will support process integration and drive characterization and data analysis for the G2 solar cell fab.

What you will do

• Develop, optimize, and own thermal and vapor deposition processes for solar cell fabrication, including PECVD and LPCVD toolsets.
• Support process integration across the G2 solar cell fab.
• Drive process characterization, DOE execution, and data analysis.
• Troubleshoot process excursions and equipment issues on CVD and thermal tools.
• Collaborate with equipment engineers and tool vendors to qualify new tools and maintain process baselines.
• Develop and maintain detailed process documentation, including recipes, SOPs, and control plans.
• Monitor process performance through statistical process control (SPC).
• Support technology transfer from development to high-volume manufacturing.
• Partner with cross-functional teams to meet cell efficiency and production targets.

Required qualifications

• Bachelor's degree or higher in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or a related field.
• 5+ years of process engineering experience in semiconductor, photovoltaic, or advanced manufacturing environments.
• Hands-on experience with PECVD and LPCVD toolsets.
• Strong working knowledge of vapor deposition processes and thermal tools and processes.
• Experience with process characterization, DOE methodology, and statistical process control (SPC).
• Proficiency with data analysis tools (e.g., Python, JMP, Excel) for process monitoring and optimization.
• Strong documentation skills and experience writing SOPs, process specs, and engineering reports.
• Ability to support a fab environment, including occasional travel to the G2 facility as needed.
• Knowledge in CVD processes — PECVD and LPCVD.
• Well versed in thermodynamics, crystal lattice chemistry, principles of diffusion and chemical kinetics, and extreme prescience in quantum chemistry.

Nice to have

• Familiarity with solar cell fabrication processes and device physics
