Job Description

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.
