Summary
👤
Senior🎓
Top SchoolJustin Garofoli is a Senior Software Engineer and mission-oriented physicist-SWE with 11 years of experience building reliable systems for safety-critical, real-world platforms. He blends rigorous scientific reasoning from a PhD in experimental high-energy physics with hands-on engineering at Waymo and Loon, where he led simulation, validation, and storm-avoidance efforts that improved steering systems (yielding two patents) and saved millions. Known for calmly navigating ambiguity, he regularly converts complex, cross-disciplinary problems into scalable tooling and processes that broaden who can run and trust simulations. Peers praise his strategic outlook, prioritization skill, and ability to boost team productivity while communicating clearly across engineering and test domains. Based in San Francisco, he brings deep expertise in simulation quality, state estimation, and hardware-in-the-loop testing—skills rooted in early work at SLAC, CERN, and LIGO that give him a rare systems-level perspective.
