Smit Sanghavi is a Staff Software Engineer based in Mountain View with 7 years of experience building large-scale systems and developer tooling at Google and DeepMind. He has progressed from backend roles in Display Ads to leading LLM tooling and infrastructure, then into tech lead management before returning to senior engineering at DeepMind, demonstrating both hands-on delivery and people leadership. Smit contributes to high-profile open-source projects like quantumlib/Cirq, where he implemented and tested quantum circuit manipulation and optimization features—an uncommon crossover between production engineering and quantum software. He focuses on robust backend systems, test automation, and pragmatic optimization of complex conversions and gate behaviors. Colleagues describe him as a practical problem-solver who balances rigorous testing with shipping impactful features. He holds a B.Tech. in Information and Communication Technology and brings a pattern of evolving technical scope across research-adjacent and production environments.
