San Francisco, California, United States
Summary
🤩
Rockstar🎓
Top SchoolMatthew Faulkner is a founder and software engineer with 11 years of experience building privacy-preserving systems and cryptographic back-ends from San Francisco. As Chief Architect at MobileCoin he led core protocol and transaction work, contributing cryptographic primitives and consensus-related refactors to a well-known private-payments project. He combines deep academic training (Ph.D. in Computer Science from Caltech) with hands-on product leadership, having transitioned from research roles at Expanse/Palo Alto Networks to founding startups. Matthew thrives on open-ended technical challenges and emphasizes that successful products require melding rigorous engineering with product and operational thinking. His background spans applied cryptography, distributed systems, and robotics, reflecting an ability to move between low-level protocol design and real-world deployments. Notably, his open-source contributions show detailed work on transaction amounts, ring signatures, and domain separation—a sign of meticulous cryptographic engineering rather than surface-level integration.
