As a Senior Physical Design Engineer, you will be responsible for the physical implementation of complex ASIC and interposer designs, from floorplanning to tapeout. You will work in a highly collaborative environment, leveraging Cadence design tools and Git for version control, ensuring efficient and high-quality execution. The ideal candidate is a self-starter who thrives with minimal supervision and has a strong background in advanced node physical design methodologies. Responsibilities Drive

full-chip physical implementation

of 2.5D interposer and ASIC designs, including floorplanning, placement, clock tree synthesis (CTS), routing, and optimization. Ensure design compliance with

timing, power, and area (PPA) requirements , as well as DFM, DRC, and LVS constraints. Utilize

Cadence tools

(Innovus, Virtuoso, Tempus, Voltus, Pegasus, etc.) for physical design, verification, and signoff. Develop and execute

timing closure strategies , working with STA engineers to meet performance goals. Optimize power

distribution networks (PDN)

and

electromigration (EM) reliability

in multi-die packaging environments. Work with

package and system engineers

to optimize die-to-die interconnect, bump placement, and TSV integration. Collaborate with

RTL designers, DFT engineers, and backend teams

to ensure seamless integration. Implement

ECOs (Engineering Change Orders)

and efficiently iterate design revisions. Utilize

Git-based version control workflows

for design database management and collaborative development. Identify and resolve

congestion, signal integrity (SI), and crosstalk

issues in complex designs. Ensure

successful tapeout

by running full-chip physical verification and working with foundry partners. Qualifications Required: 5+ years of experience

in physical design, specifically in

ASIC, SoC, or advanced packaging (2.5D, 3DIC)

technologies. Hands-on experience with

Git-based version control systems

for managing design revisions. Experience with

timing closure and signal integrity . Preferred: Experience in

2.5D/3DIC packaging

and heterogeneous integration. Hands-on experience with

chip-package co-design

methodologies. Prior engagement with

foundry process nodes and PDKs

for advanced packaging. Skills Required: Proficiency in

Cadence tools

for physical design, timing analysis, and signoff. Strong understanding of

RTL-to-GDSII flows , including floorplanning, power planning, place-and-route, and timing closure. Working knowledge of

parasitic extraction (PEX), power integrity (PI), and thermal analysis

in multi-die environments. Ability to

work independently

with minimal supervision and drive tasks to completion. Excellent verbal and written

communication skills

for collaboration across engineering teams. Strong

debugging skills

and ability to analyze tool reports, logs, and simulation results. Preferred: Familiarity with

high-speed die-to-die interconnect design and CoWoS/Fanout-WLP processes . Knowledge of

scripting (TCL, Python, Perl, or shell scripting)

to automate design tasks. Job Location More Information For company description, benefits package, and application instructions see the Careers Page
