Development Engineer IV USA

About the role

First Solar reserves the right to offer you a role most applicable to your experience and skillset.

Responsibilities

• Serve as a senior technical contributor with First Solar’s Perovskite pilot line department focusing on Perovskite photovoltaic device physics-based root cause and failure analysis.
• Support development and scale-up of First Solar’s next-generation perovskite technology.
• Operate at the intersection of materials science, device physics, and pilot manufacturing engineering, acting as a technical leader in defining root cause characterization and analysis strategies, correlating metrology data to performance and reliability, and resolving complex process-structure-property relationships.
• Develop mechanistic root cause analysis methodology for perovskite pilot line, enabling improved process control, faster learning cycles, and robust yield and performance outcomes.
• Responsible for performing deep root cause investigations of yield loss, efficiency variability, and reliability excursions using metrology data, physics-based models, and cross-functional inputs.
• Lead failure analysis and excursion response efforts, including hypothesis generation, experimental design, data interpretation, and corrective action definition.
• Develop and validate mechanistic understanding linking perovskite deposition, crystallization, and post-processing to device-level electrical and environmental performance.
• Support DOE development, parametric studies, and technology readiness assessments tied to pilot production goals.
• Serve as a subject-matter expert in perovskite photovoltaic device physics and physics-based diagnostics for internal stakeholders.
• Mentor junior engineers and scientists in experimental rigor, data analysis, and problem-solving methodologies.
• Author and review technical reports, internal white papers, and invention disclosures; contribute to IP generation where applicable.
• Collaborate with external partners, national labs, and equipment vendors.
• Contribute to continuous improvement of said policies.

Requirements
