Job Title: IO Layout Engineer
Experience: 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.
- Strong 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 interfa
