Summary
🤩
Rockstar🎓
Top SchoolSarthak Khattar is an open-source-minded systems engineer with eight years of experience building secure, large-scale infrastructure and core systems. Currently an OpenLambda developer and MS candidate at UW–Madison, he brings a hardware-rooted perspective (BTech in ECE) to software problems—working on rootless container execution, cgroups delegation, and multi-tenant deployment. He previously built Chegg’s AI-native Q&A platform features and real-time moderation pipeline, served as the security point of contact, and contributed production-grade analyzers and security fixes to the IntelOwl threat-intel project. His research on LLM robustness and tooling for software assurance complements hands-on product delivery, and he’s comfortable navigating both low-level OS primitives and cloud-scale service design. Quietly opinionated about tooling (he runs Arch), Sarthak seeks 2026 new-grad roles focused on reliable, secure systems at scale.
