Rockstar🎓
Top SchoolPhil Ammirato is a Senior Applied Scientist with 26 years of engineering experience, currently building production ML and applied-science solutions at Samsara in San Jose. He blends deep research credentials—a PhD and MS from UNC Chapel Hill—with hands-on systems and DevOps expertise, having contributed to projects from kernel USB quirks to infrastructure automation in Chef and Meta's client tooling. His background spans computer vision research roles at Vicarious and internships at NVIDIA, plus a sustained open-source footprint across widely used tools like chef, ohai, markdownlint, and hub. Phil is comfortable moving models into robust, observable platforms and has a track record of pragmatic fixes and tooling improvements that keep fleets reliable at scale. Notably, he pairs low-level embedded/kernel work with high-level scientific modeling—an unusual combination that helps bridge prototype research and production readiness. Outside work he’s an open-source developer and Metallica super-fan, a detail that hints at his long-term focus and intensity.
