Summary
👤
Senior🎓
Top SchoolJoshua Chao is a Senior Software Security Engineer in San Francisco with a decade of experience building secure product and infrastructure for privacy, fintech, and large-scale consumer platforms. He has driven mission-critical migrations and encryption initiatives at Meta—moving Tier-0 financial services into AWS, designing data-at-rest encryption and PKI tooling—and now applies that expertise to product/infra security at Zip. His background spans low-level performance tooling, fraud detection with big-data ML, and mobile AR integrations, giving him a rare blend of systems, data, and product security experience. Josh pairs hands-on engineering with security stewardship, having served on an elite security council that acts as a launch blocker for financial products. Outside work he’s a methodical problem-solver—brewing cappuccinos, playing tennis, and reading sci-fi—which echoes his pragmatic but curious approach to complex security problems.
