Head Of Design at Company Sage
California, United States
Summary
🤩
RockstarBrian Lonsdorf is an AI-native engineering leader and Head of Design based in California with 11 years of professional experience blending research-driven UX, generative UI, and design systems. He led UX R&D architecture at Salesforce for seven years, bringing product-grade rigor to experiments in retrieval-augmented generation and human-centered AI interfaces. Earlier roles as an owner/operator and web developer reflect deep hands-on fluency—from Haskell projects to shipping production UIs—so he bridges prototyping and scalable design implementation. Known for translating R&D into usable design systems, he thrives at the intersection of creative design and engineering discipline. An investor in pragmatic tooling, he quietly favors functional programming approaches that improve maintainability and developer experience.
