  • 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
  • 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 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.
  • T1 Energy is an Equal Opportunity Employer. We are committed to creating an inclusive environment for all employees and applicants and do not discriminate on the basis of any legally protected characteristics.

  • 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
