Designed tests to assess iron redox flow battery (IRFB) system performance and reliability consistent with product specifications• Spearheaded 5 pressure and fluid flow data-driven product design changes to improve reliability• Characterized system electrolyte movement and round-trip efficiency (RTE) during standardized battery cycling to develop new pass criteria for end-of-line (EOL) testing and maximize product quality• Developed detailed operating instructions (OIs) for field service engineers to identify undesirable electrolyte crossover due to membrane defects• Led failure analysis (FA), stack teardown, safety investigation, and remediation efforts after critical system failure• Collaborated with R&D team to design and test an electro-optical sensor prototype that detected undesirable chemical side reactions to increase system availability and efficiency• Advised on ideal flow battery cycling conditions to maximize system efficiency and customer satisfaction• Coordinated multiple teams for prototype validation testing during new product introduction (NPI) process and participated in piping and instrumentation diagram (P & ID) review• Executed hands-on troubleshooting and organized non-standard system maintenance while emphasizing safety• Scripted battery cycling tests
