Top SchoolTimothy Trippel is a Staff Software Engineer at Google with a decade of experience building secure embedded systems and Root-of-Trust hardware for data centers, client devices, and mobile platforms. He was a core contributor and one of the top five contributors to the OpenTitan project, helping drive its first commercial-grade tapeout and bring-up and authoring key tooling such as Python DIF status reporting. His expertise spans secure boot, DICE attestation, code-signing/HSMs, provisioning, fuzzing of RTL models, and even IC design and verification—bridging firmware, DV, and infrastructure. A published security researcher with papers at USENIX, Oakland, and CHES, he brings academic rigor to practical silicon security problems. Based in Mountain View, he combines deep low-level engineering with large-scale infrastructure experience, including building GCP-based fuzzing pipelines for hardware models.
