The Rundown AI, Inc.
ABOUT THE ROLE
We are seeking an experienced Silicon Packaging Layout Engineer with expertise in heterogeneous integration. The ideal candidate will have a strong background in semiconductor packaging design to drive Celestial AI’s Photonic Fabric Package solutions. This role requires cross-functional design collaboration with multiple engineering groups, such as Packaging, ASIC, AMS, Photonics, and external partners to ensure design for manufacturing, assembly, reliability, and cost.
ESSENTIAL DUTIES AND RESPONSIBILITIES
2.5D and 3D Design Planning and Execution:
Support Silicon interposer and RDL based design planning and execution for advanced packaging architectures. Support bumpmap and test collateral release for test vehicle and product designs. Netlist management for heterogeneous chiplet assemblies using latest EDA solutions.
Layout Expertise:
Support all aspects of silicon layout based on 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. Support cross-functional silicon layout needs.
Fab and OSAT Engagement:
Support activities related to silicon manufacturing such as fab design reviews and tape-out aligned with OSAT requirements. Actively support test vehicle definition and design for assembly test vehicles.
QUALIFICATIONS Education:
BS in EE/ECE/MSE/ME/ChemE or related disciplines. Experience:
4 years of experience in silicon interposer and RDL designs for heterogeneous architectures. Technical Expertise:
Experience working with design tools such as Cadence Virtuoso and Klayout. Familiarity with AutoCAD tools and file formats. Layout experience for various 2.5D/3D packaging technologies including InFO, CoWoS, FoCoS and EMIB. Familiarity with cross-functional packaging areas: Si floor plan, package, assembly design rules, BOM, enabling material/process technologies, thermal, mechanical, Signal/Power Integrity, design for manufacturing, assembly, reliability, and cost. Familiarity with photonics packaging is a plus but not necessary.
Foundry and OSAT Engagement:
Experience working with wafer foundries to meet design for manufacturing, yield, and reliability. Experience working with OSATs to meet assembly requirements.
Industry Knowledge:
Familiarity with latest advanced packaging architectures. Soft Skills:
Strong analytical, problem-solving, cross-functional collaboration, project management, and technical presentation skills. PREFERRED QUALIFICATIONS Experience in silicon layout for heterogeneous integration, fan-out packaging, chiplet architectures – co-design, physical layout, and netlist management. Experience with fab and assembly design rules. Experience in foundry and OSAT assembly engagement to meet manufacturing and assembly requirements. LOCATION
: Santa Clara, CA For California Location: As an early stage start up, we offer an extremely attractive total compensation package inclusive of competitive base salary, bonus and a generous grant of our valuable early-stage equity. The target base salary for this role is approximately $165,000.00 - $205,000.00.
