Senior I/O Layout Engineer

Location: Bengaluru, India

Experience: 4–12 Years

Technology Nodes:

- TSMC: A14 (14Å), N2 (2nm), N3 (3nm), N5 (5nm)
- Samsung: SF2 (2nm), 4nm

Role Overview We are seeking highly skilled I/O Layout Engineers with solid hands-on expertise in full-custom I/O layout design across advanced technology nodes. The ideal candidate will have experience in I/O cell development, transistor-level layout, physical verification, and PPA optimization, with a deep understanding of FinFET and GAA/nanosheet technology constraints.

Key Responsibilities

- Develop and optimize full-custom layouts for I/O cells, GPIO, bidirectional buffers, level shifters, and ESD protection circuits.
- Implement layouts for I/O drivers, receivers, high-voltage-tolerant interfaces, and power/ground I/O cells.
- Drive transistor-level floorplanning, device placement, routing, and layout optimization.
- Optimize layouts for area, parasitics, signal integrity, electromigration, and reliability.
- Ensure compliance with advanced-node foundry design rules and I/O-specific electrical constraints.
- Perform physical verification, including DRC, LVS, ERC, antenna checks, and latch-up-related checks.
- Execute parasitic extraction (PEX) and support post-layout simulation and design closure.
- Address advanced-node challenges involving restricted routing, layout-dependent effects (LDE), density rules, and device matching.
- Collaborate with circuit design, ESD, reliability, and physical verification teams to achieve tape-out readiness.




- Own block-level layout development from schematic handoff through physical verification sign-off.

Required Technical Skills

- 4–12 years of hands-on experience in full-custom I/O layout design.
- Strong expertise in I/O cell layout, GPIO, I/O buffers, level shifters, and ESD structures.
- Experience with advanced technology nodes, preferably TSMC 5nm/3nm/2nm/A14 or Samsung 4nm/2nm.
- Strong understanding of FinFET and GAA/nanosheet layout methodologies, including foundry-specific design rules.
- Proficiency in Cadence Virtuoso Layout Suite.
- Hands-on experience with Siemens Calibre / Cadence Pegasus / Synopsys IC Validator or equivalent physical verification tools.
- Strong expertise in DRC/LVS debugging, parasitic extraction, and layout sign-off.
- Understanding of ESD protection, latch-up prevention, power routing, and I/O reliability requirements.
- Experience with multi-voltage-domain layout, guard rings, isolation, and noise-sensitive routing.

Preferred Qualifications

- Direct layout experience on TSMC N5/N3/N2/A14 or Samsung 4nm/2nm processes.
- Experience in advanced-node I/O libraries, pad-ring integration, and I/O macro development.
- Exposure to ESD-aware layout, high-current I/O structures, and reliability verification.
- Knowledge of high-speed I/O or mixed-signal interface layout.
- Experience with complete layout ownership, physical verification closure, and tape-out.
- B.E./B.Tech or M.E./M.Tech in Electronics, Electrical Engineering, Microelectronics, or related disciplines.
