About Celestial AI
As the industry strives to meet the demands of the AI workloads, bottlenecks in data transfers between processors and memory have hindered progress. The Photonic Fabric based Memory Fabric provides an optically scalable solution to the ‘Memory Wall’ problem, enabling tens of Terabytes of memory capacity at full HBM bandwidths with low tens of nanoseconds of latency and extremely low power. The Photonic Fabric based Compute Fabric enables Terabyte class bandwidth between compute nodes at low latency and power. Photonic Fabric delivers a transformative leap in AI system performance, ten years more advanced than existing technologies.
Job Description:
In this role you will utilize your broad semiconductor package layout and design experience in designing package solutions to drive company’s Photonic Fabric family of products from concept to high volume manufacturing. You will be responsible for package design activities with multiple engineering groups, such as Packaging, ASIC, AMS, Photonics and external partners to ensure design for manufacturing, reliability, and cost. This job will require you to have strong project management, written and verbal communication skills as well as a can-do attitude to prioritize and work on projects with a high sense of urgency.
ESSENTIAL DUTIES AND RESPONSIBILITIES:
- All aspects of package design and layout at Silicon, interposer and substrate level for multi-chip SiP packaging
