Master’s Degree in an engineering discipline or similar technical discipline and 3 years of relevant technical experience, or 2 years of experience as a Development Engineer I at First Solar. Ph.D. in an engineering discipline or similar technical discipline, without prior technical work experience. Experience with perovskite devices, preferred. Proficiency in scientific programming tools (e.g., Python, MATLAB), preferred. Familiarity with degradation studies and reliability testing, preferred. Experience in industrial or applied research settings, preferred. Required Skills / Competencies Excellent understanding of semiconductor physics, optoelectronics, and photovoltaic device operation. Hands‑on experience in executing experiments in a laboratory or manufacturing environment. Hands‑on experience with a variety of electro‑optical device characterization techniques (e.g., JV, EQE, PL, TRPL, transmission‑reflection, impedance spectroscopy). Strong understanding of materials analysis techniques (e.g., SIMS, SEM, EDS, GDOES). Strong statistical data analysis skills. Excellent problem‑solving skills and ability to work independently and in teams. Strong sense of project ownership with a can‑do attitude. Strong communication skills across organizations. Essential Responsibilities Perform perovskite device characterization, analysis, and root‑cause segmentation to quantify performance and diagnose underperformance. Identify opportunities for improvement in solar cell performance and reliability, and in methods and tools for characterization. Improve state‑of‑the‑art techniques for perovskite solar cell characterization and statistical analysis. Develop work plans for problems with unclear solution paths. Determine and evaluate material specifications for improved performance; determine and evaluate tool/equipment specifications. Communicate effectively with internal and external partners and customers. Collaborate as a team member to support cross‑functional projects and take ownership of sub‑deliverables. Train, mentor, and manage junior associates on specific subject matters, if applicable. Comply with company environmental, quality, safety, and other policies; contribute to continuous improvement of those policies. Other duties as assigned.
