Summary
👤
Senior🎓
Top SchoolSagi Grimberg is a seasoned software architect and engineering leader with 11 years focused on real-time systems, storage, networking and virtualization, currently serving as VP of Architecture at VAST Data. He co-founded Lightbits Labs and previously led storage software teams at Mellanox, where he drove RDMA, NVMe and kernel-level features and maintained critical iSER initiator/target drivers. Deep in Linux kernel and user-space development, Sagi is fluent in C/C++, Python and Bash and brings hands-on expertise in RDMA (including fabrics and NVMe-oF), storage offloads and advanced data-integrity features. He contributes to notable open-source projects such as nvme-cli, improving fabrics support and discovery workflows, reflecting a practical blend of product and upstream maintenance. Based in Israel with a B.Sc. in Computer Engineering from Bar-Ilan University, he pairs founder-level strategic thinking with day-to-day kernel hacking. An underappreciated strength is his sustained role as a kernel subsystem co-maintainer, which keeps his architectural decisions tightly informed by implementation realities.
