Staff/Senior Staff Physical Design Floorplan

Experience: 10–14 Years

Location: Bangalore/2 days to work

Department: RTL-to-GDSII / Physical Implementation

Role Overview

We are seeking a high-caliber Staff or Senior Staff Physical Design Engineer with a specialized mastery of Floorplanning design. You won’t just be pushing buttons; you will be the architectural bridge between RTL/Systems and the final GDSII. This role requires a visionary who understands how a single floorplan decision ripples through the entire PPA (Power, Performance, Area) spectrum.

As a technical lead, you will own the chip-top floorplan for complex, large-scale SoCs or Sub-chips, driving strategies that balance aggressive performance targets with robust power integrity.

Key Responsibilities

• Architectural Floorplanning: Lead chip-level floorplanning, including macro placement, pin assignment, and partition definition for multi-million gate designs.
• EMIR Mastery: Perform exhaustive IR-drop (Static/Dynamic) and Electromigration (EM) analysis. You must be able to diagnose root causes and propose architectural or physical fixes that don't compromise timing.
• Cross-Functional PPA Trade-offs: Collaborate directly with RTL and Architecture teams. You will use "Design Thinking" to influence the micro-architecture, suggesting changes to bus widths, pipeline stages, or memory configurations to optimize physical outcomes.
• Methodology Development: Establish best practices and automated flows for floorplanning and PDN synthesis to be used by the wider implementation team.

Technical Requirements

• Core Experience: 10+ years in Physical Design with a proven track record of multiple successful tape-outs at advanced nodes (7nm, 5nm, or 3nm).
• PDN Expertise:Ability to model complex power-up sequences and multi-voltage domains.
• Floorplanning Savvy: Deep proficiency in hierarchical physical design and top-level integration using industry-standard tools (Innovus or IC Compiler II).
• Analysis Skills: Strong understanding of thermal-aware PDN and the physical implications of high-current density paths.
• Scripting: Advanced proficiency in Tcl, Python, or Perl to automate complex floorplanning tasks and data analysis.

Behavioral Attributes

• Critical Thinker: You don't just follow a recipe. You question constraints and look for "hidden" PPA gains.
• Design Thinking: Ability to empathize with the challenges of upstream (RTL) and downstream (Sign-off) teams to create a holistic solution.
• Influence: You can articulate technical trade-offs to stakeholders,

Education

• B.Tech/M.Tech in Electrical/Electronic Engineering or equivalent.
