• Initiated and steered discussions to inform stakeholders of production issues and risks, using tools such as JIRA and Google Sheets to clearly establish ownership and responsibilities for action items.
• Liaison to contract manufacturer for initial production runs, responsible for in-process deviations, build issue documentation, reconciliation of BoMs, and on-the-floor engineering decisions. Delivered over $150k in.

• Green technology start-up commercializing a new battery chemistry for grid-scale energy storage.
• Scoped and executed full-cycle product development plans to bring successively lower cost versions of the core product to market.
• Led engineering teams to implement production changes, resolve supplier quality problems, and develop the next generation of product designs.
• Identified process gaps, established best practices, and collaborated cross-functionally to scope and implement improvements to the Product Development Process.
• Investigated and resolved product quality issues using Root Cause Analysis tools such as 5 Whys and FMEAs.
• Developed custom data collection systems to monitor and log force, displacement, pressure, temperature, and strain procured and created metrology and test equipment, and construction of prototype fixtures.
