Package Design Engineer Jobs

:

ESSENTIAL DUTIES AND RESPONSIBILITIES:

• Drive ideation and innovation of advanced package solutions and specifications with vendors to advance productization efforts by Celestial AI
• Si/package/PCB/system co-design work collaborating with downstream system design teams and upstream ASIC designers to develop a portfolio of packages that meets a huge range of performance design points, while optimizing re-use in other Celestial AI products
• All aspects of package design planning at Silicon, interposer and substrate level for multi-chip SiP packaging, including design feasibility, pre/post silicon bring up, and support yield improvement activities, qualification, failure analysis, and system implementation
• All aspects of package design/layout based on Si I/O, Si PI and form factor requirements, including routing, design for reliability, thermal, mechanical, manufacturability, bumping, substrate, material selection, assembly, and support for testing
• Meeting specifications for high-speed interfaces such as HBM, DDR, PCIE and 56G/112G SerDes
• Work with cross-functional teams and support package integration and architecture efforts with vendors
• Supporting activities related to production and assembly of IC packages with OSAT and substrate suppliers
• Actively participate in qualification of package and board level assembly with sensitivity to physics of failures for high thermo-mechanical reliability

QUALIFICATIONS:

• Experience working with MCAD tools such as SolidWorks, AutoCAD and interconversion of package design databases to MCAD files
• Knowledge and insights to deliver high density/high performance interconnects in various 2.5D/3D package form factors including InFO, CoWoS, FoCoS and EMIB
• Extensive experience working with advanced packaging tools such as Cadence APD
• Familiarity with component & system level reliability, testing, and FA
• Effective communicator and comfortable engaging with internal cross functional teams as well as domestic and overseas suppliers
• 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
• Experience in project management and communicating technical and project/program status and issue resolution at all levels of the engineering organization
• Excellent problem-solving skills with strong fundamentals in science, sound engineering judgment, and analytical ability
• 10+ years of experience in Semiconductor Packaging Design, with at least 6 years of hands-on experience in Advanced Package design
• 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
• BS/MS/PhD in EE/ECE/MSE/ME/ChemE or related disciplines
• Familiarity with photonics packaging is a plus but not necessary
