Singapore beBeePhotonic Full time $150,000 - $200,000
Job Description:

As AI technologies continue to advance, data center infrastructure performance drivers are shifting from systems-on-chip (SOCs) to systems of chips.

Data center bottlenecks are no longer limited to compute performance but rather the system's interconnect bandwidth, memory bandwidth, and memory capacity.

Celestial AI's Photonic Fabric is a next-generation interconnect technology delivering tenfold increases in performance and energy efficiency compared to competing solutions.

The Photonic Fabric is available to customers in multiple technology offerings, including optical interface chiplets, optical interposers, and Optical Multi-chip Interconnect Bridges (OMIB).

This allows customers to easily incorporate high-bandwidth, low-power, and low-latency optical interfaces into their AI accelerators and GPUs.

The technology is fully compatible with both protocol and physical layers, including standard 2.5D packaging processes.

This seamless integration enables XPUs to utilize optical interconnects for both compute-to-compute and compute-to-memory fabrics, achieving bandwidths in the tens of terabits per second with nanosecond latencies.

This innovation empowers hyperscalers to enhance the efficiency and cost-effectiveness of AI processing by optimizing the XPUs required for training and inference, while significantly reducing the TCO impact.

To bolster customer collaborations, Celestial AI is developing a Photonic Fabric ecosystem consisting of tier-1 partnerships that include custom silicon/ASIC design, system integrators, HBM memory, assembly, and packaging suppliers.
