Celestial AI AI Jobs & Careers
infoAbout Celestial AI
Celestial AI is the creator of Photonic Fabric, a revolutionary optical interconnect technology platform that uses light instead of electricity to move data between compute and memory in AI data centers. The technology addresses the critical bandwidth and energy bottleneck facing modern AI infrastructure by delivering up to 16 terabits per second of bandwidth in a single chiplet -- 10 times the capacity of today's state-of-the-art networking ports -- enabling optically scalable, disaggregated data center architectures. Founded in 2020 by CEO David Lazovsky and COO Preet Virk, Celestial AI offers a full suite of connectivity, switching, and packaging solutions that serve as the foundation for optical scale-up networks in accelerated computing environments. The company's Photonic Fabric chiplet integrates all required electrical and optical components into a compact form factor, providing hyperscale cloud providers with the foundational building blocks for next-generation AI clusters. Celestial AI raised over $520 million in total funding from investors including Fidelity, BlackRock, Tiger Global, TSMC, and Samsung, reaching a $2.5 billion valuation. In February 2026, Marvell Technology completed its acquisition of Celestial AI in a deal valued at over $3.25 billion, validating the transformative potential of photonic interconnect technology. For hardware engineers and photonics researchers, Celestial AI represents a rare opportunity to work on the physical infrastructure breakthroughs that will define the next decade of AI scaling.
