3+ Years Location:

Bangalore Employment Type

Full-time Industry:

Semiconductors / ASIC / VLSI / IO & ESD Design Job Summary: We are looking for a highly motivated and experienced

IO Layout Engineer to join our custom layout team. The candidate will be responsible for full-custom layout of IO cells, ESD protection structures, and high-voltage interfaces for ASIC/SoC applications in deep submicron and FinFET technologies.

Key Responsibilities

Perform transistor-level custom layout of various types of IO cells including: Standard IOs (CMOS, LVTTL, LVCMOS, SSTL, HSTL) High-speed and specialty IOs (DDR, USB, PCIe, HDMI, etc.) ESD structures, pad rings, and protection circuits Work closely with IO circuit designers to interpret schematics and design intent.

Ensure robust layout practices for: ESD compliance Latch-up prevention Electromigration (EM) Voltage isolation and guard ring planning Ensure layout meets foundry-specific DRC, LVS, and antenna rules. Run and close physical verification (DRC, LVS, ERC, ANT) using industry-standard tools. Participate in floorplanning of IO ring and integration with analog/digital blocks. Coordinate with packaging,



ESD, and reliability teams to support silicon tapeout.

Required

Skills and Experience: B.E/B.Tech or M.E/M.Tech in Electronics, Electrical Engineering, or VLSI. 3+ years of hands-on experience in IO and/or ESD layout. Robust understanding of ESD protection concepts and latch-up avoidance. Expertise in Cadence Virtuoso for layout design and implementation.

Experience with DRC/LVS tools (Calibre, Assura, PVS). Familiarity with advanced process technologies (28nm, 16nm, 7nm, FinFET, etc.). Good knowledge of layout-dependent effects (LDE), IR drop, and reliability constraints. Attention to detail and strong debugging/problem-solving skills.

Preferred Qualifications

Experience in high-voltage or multi-voltage IO layout (1.8V/3.3V/5V interfaces). Experience with IO ring planning and integration in complex SoC floorplans. Familiarity with power grid design, bump/ball map coordination, and ESD co-design. Scripting experience in SKILL, Tcl, or Python for layout automation.
