This is an exceptional opportunity to showcase your engineering skills in a dynamic, fast-paced environment that fosters innovation and operates at the forefront of technology.
 
High-Speed Digital Design
  • Develop high-speed digital layouts, including DDR and other high-speed interfaces.
  • Expertise in floor planning, bump planning, routing, power grid design, clock design/distribution, and optimization for high-speed digital circuits.
  • Optimize layouts to minimize signal integrity issues, reduce power consumption, and meet timing, power, and manufacturability requirements.
  • Coordinate with PHY vendors for hardening activities and deliverables.
  • Estimate effort and timelines for PHY hardening tasks and provide feedback on timing/PDV.
Chip-Level Physical Design
  • Perform chip-level tasks such as floor planning, partitioning, and power/clock distribution.
  • Handle chip assembly and ensure seamless integration of multiple IP blocks into the top-level design.
  • Proficiency in using EDA tools for chip-level physical verification (DRC, LVS, ERC).
  • Collaborate with the packaging team to refine bump placement and package routing considerations.
Signal and Power Integrity
  • Familiarity with signal and power integrity concepts in high-performance memory systems.
  • Expertise in managing high-speed signals to mitigate issues like crosstalk, reflection, and signal degradation.
  • Perform thermal and power integrity analysis to ensure reliable designs.
  • Knowledge of advanced packaging techniques and considerations, an added plus
Design-for-Test (DFT)
  • Basic understanding of DFT structures, including scan chains, MBIST, and loopback mechanisms.
  • Contribute to DFT-based timing closure activities.
About you:
  • Expertise in floor planning, bump planning, routing, power grid design, clock design/distribution, and optimization for high-speed digital circuits
  • Experience developing high-speed digital layouts, including DDR and other high-speed interfaces
  • Handling chip assembly and ensure seamless integration of multiple IP blocks into the top-level design
  • Proficiency in using EDA tools for chip-level physical verification (DRC, LVS, ERC)
  • Worked with architects and RTL teams to develop physical constraints and optimize their design
  • Integrate PHYs, controllers, and memory stacks into the top-level design
  • Expertise in managing high-speed signals to mitigate issues like crosstalk, reflection, and signal degradation
  • Experience with advanced packaging technologies, such as 2.5D/3D integration, TSV, and interposer-based designs
  • Handle micro-bump design to ensure proper alignment and minimize resistance
  • Understand the SIPI impacts of bump placement
  • Basic understanding of DFT structures, including scan chains, MBIST, and loopback mechanisms
  • Strong communication and articulation skills are required to excel in this role
  • Electrical or Computer Engineering - Bachelor's degree & 8 years of related experience; or Master's degree & 6 years; or PhD & 3 years
