Summary
Hao Wu is a Principal Software Engineer based in Palo Alto with a decade of hands-on experience building security-first cloud data management features at Rubrik. He has progressed from core engineering to leading product security and serving as an area tech lead, architecting systems for encryption, PKI, trusted computing, key management, and enterprise authentication and authorization. Hao combines deep research roots—a PhD from UIUC and publications on network monitoring and trusted boot—with practical impact from internships at Facebook, Amazon, and Microsoft that improved spam detection, search, and large-scale data tooling. He is particularly adept at turning rigorous security primitives (TPM, HSM, Vault, code signing) into production-ready, auditable workflows for multi-tenant cloud platforms. Colleagues know him for bridging research-level cryptographic and systems ideas with pragmatic engineering deliverables that scale in complex enterprise environments.
