Samuel Jo is a Senior Engineering Manager based in New York with 10 years of experience building performant web products and developer platforms. He has led teams at Oscar Health and The Muse, where he founded a site-performance and platform group that delivered concrete wins like a ~20% CSS reduction to improve time-to-first-paint. Technically grounded in Ruby on Rails, JavaScript, and React, Samuel pairs hands-on full-stack engineering with platform thinking to enable other teams to grow and ship faster. His background in applied physics and semiconductor process engineering gives him a data-driven, systems-oriented approach to optimization and reliability. He thrives in transparent, mission-led cultures and often cites the collaborative team environment as his primary motivation. Outside work he enjoys hiking, sports, and movies, bringing a pragmatic curiosity from scientific research into product engineering.
