Principal Package Integrator

Santa Clara, CA

About Celestial AI

As Generative AI continues to advance, the performance drivers for data center infrastructure are shifting from systems-on-chip (SOCs) to systems of chips. In the era of Accelerated Computing, 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 the next-generation interconnect technology that delivers a tenfold increase in performance and energy efficiency compared to competing solutions.

The Photonic Fabric™ is available to our 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 TCO2 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.

Job Description: 

 

In this role you will utilize your broad semiconductor packaging experience and partner management experience to drive company’s HPC products from concept to high volume manufacturing. You will be responsible for driving engineering activities with multiple engineering groups such as Packaging, ASIC, AMS, Photonics and external partners to ensure design for manufacturing, reliability, and cost. Responsibilities will include identification and mitigation of risk to new technologies used in product integration and ensure factory readiness through maturing product during the NPI phase. 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 address issues with a high sense of urgency. 

 

ESSENTIAL DUTIES AND RESPONSIBILITIES: 

  • Work with cross-functional teams and lead package integration and architecture efforts with vendors
  • Work with small to large scale 3rd party vendors, foundries and OSATs to bring packaging solutions from concept to prototypes and ramp to high volume manufacturing with aggressive cost reduction strategies.
  • Actively manage qualification of package and board level assembly with sensitivity to physics of failures for high thermo-mechanical reliability, while operating within established cost constraints
  • Manage internal and external resources effectively and efficiently for thermal/mechanical/electrical simulations and package layouts
  • Drive ideation and innovation of advanced package solutions and specifications with vendors to advance productization efforts by Celestial AI

 

QUALIFICATIONS: 

  • 15+ years of experience in Semiconductor Packaging Design, Process and/or Technology Development
  • Experience in project management and communicating technical and project/program status and issue resolution at the executive level
  • Expertise in advanced packaging technologies: knowledge and insight to deliver high density/high performance interconnects in various 2.5D/3D package form factors
  • Good understanding of cross-functional packaging areas: Si floor plan, package and board level layout and architecture, design rules, BOM, enabling material/process technologies, thermal, mechanical, Signal/Power Integrity, design for manufacturing, reliability, and cost
  • Familiarity with component & system level reliability, testing, and FA
  • Experience with photonics packaging is a plus but not necessary
  • Excellent problem-solving skills with strong fundamentals in science, sound engineering judgment, and analytical ability
  • Effective communicator and comfortable engaging with internal cross functional teams as well as domestic and overseas suppliers
  • Excellent attention to detail, process and operationally oriented and self-driven with the ability to work independently and take projects to completion with minimum supervision
  • MS or Ph.D. in Electrical Engineering, Mechanical Engineering, Materials Science or Physics is required

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
