Rockstar🎓
Top SchoolYifei Xu is a software engineer with six years of experience building AI infrastructure and high-performance ML runtimes, now working on PyTorch at Meta Superintelligence Labs after contributing to Core ML Runtime at Google. He brings deep systems and numerical expertise from a Ph.D. in reservoir simulation, where he developed advanced fracture modeling and grid-generation algorithms, and has translated that into production work on distributed training and serving for TensorFlow, JAX, and IFRT. His background spans C++, Python, JAX, TPU work, and cloud-native tooling—including Terraform, Kubernetes, and microservices—giving him fluency across research-grade algorithms and production ML platforms. At ExxonMobil he led small engineering teams to deliver simulation and optimization software, demonstrating both technical leadership and domain-driven product delivery. Comfortable moving between low-level performance engineering and higher-level infrastructure, he’s equally at home optimizing distributed runtimes or designing resilient deployment stacks. Based in the Bay Area, he blends rigorous academic modeling experience with hands-on cloud and ML systems engineering.
