• Strong self-direction, initiative, and ability to prioritize multiple tasks from various requestors, demonstrated ability to manage multi-faceted projects.
• Demonstrated results in developing and delivering customer-facing technical collateral.

Essential Responsibilities:

• Develop Artificial Intelligence/Machine Learning based algorithms such as energy prediction model, solar irradiance (GHI, POA) model, spectral correction model, device metastability model, and module degradation model to enable fast learning of product performance.
• Automate end-to end ETL and ML pipelines, deploy and maintain existing on-prem and Azure storage.
• Collaborate with data scientists and analytics team to deploy models, monitor performance and orchestrate continuous integration of model artifacts.
• Conduct data cleaning, preprocessing, and analysis of massive datasets to identify significant trends, ensuring that the data used for model training is of the highest quality. 
• Take ownership of data quality improvement in First Solar's field test sites. Assist in data analysis and state-of-the-art instrumentation and test equipment development. Forecast/Model long-term energy performance of First Solar modules in production/field environments, perform model vs actual analysis on a periodic basis. Identify areas of improvement in the models. Validate model predictions with measured data from plant monitoring systems and field test results.
• Evaluate the feasibility of new products, model energy performance of new module technologies under various meteorological climates, improve model through successive iterations, ensemble results to develop a robust model and validate model prediction with testbed before production deployment.
• Support methods for verifying the capacity of installed solar PV systems and required customer reported performance metrics. Use standard root cause analysis techniques to identify areas of improvement and provide recommendations to support customer complaints.
• Document code, models, approaches, and experiments to ensure clarity and promote knowledge sharing among team members.
• Job description subject to change at any time.
