Senior🎓
Top SchoolRoger L is a development engineer with nine years of hands-on experience bridging materials science, mechanical design, and battery testing, currently driving development at First Solar in Seattle. He brings a strong lab foundation from an MS at UC Berkeley and contributed to peer-reviewed work on CVD-grown tin sulfide, translating research rigor into practical product testing and safety systems. At Cuberg he led safety documentation, built a custom test chamber used for most company testing, and supported customer-facing technical testing—demonstrating both experimental depth and operational ownership. Comfortable with electrical testing, glovebox operations, and data wrangling, he excels at turning complex experimental protocols into repeatable, auditable workflows. Pragmatic and safety-minded, Roger looks to deepen his mechanical and materials engineering impact within mission-driven organizations.
