Summary
🤩
RockstarSujay Jayakar is a Member of Technical Staff at Anthropic with a decade of experience building high-performance distributed systems, storage platforms, and developer-facing infrastructure. He co-founded Convex and served as Head of Engineering for infrastructure at Cursor, bringing both startup agility and large-scale product leadership from roles at Dropbox and Microsoft Research. At Dropbox he led Sync and Magic Pocket efforts—designing petabyte-scale storage, SMR-supporting nodes, and a journaled filesystem—and at MSR rewrote a TCP stack in Rust for microsecond-scale datacenter RTTs. He contributes across the stack in open source too, from front-end UI and PixiJS work on a16z-infra’s AI Town to low-level TCP/UDP improvements in Microsoft’s Demikernel project. Based in New York with a BA in Math and Economics from Cornell, Sujay combines systems-level rigor with an eye for polished user experiences and a knack for turning research prototypes into production-grade services. An under-the-radar strength is his ability to move seamlessly between kernel-bypass networking and user-facing UI polish, making him unusually versatile across layers.
