About the role

Job description:

Manage the complete custom layout process for SRAM bitcell arrays, memory periphery, test structures, and memory macros in advanced CMOS technologies.
Develop and improve floorplans for SRAM and memory blocks, covering array layout, periphery positioning, power grid design, routing channels, and macro assembly.
Carry out, debug, and complete DRC, LVS, ERC, antenna, and associated physical verification checks with tools such as Calibre, ICV, or similar workflows.
Support EM/IR review, power integrity, density/fill, DFM, dummy insertion, layout-dependent effects, and other requirements for tapeout.
Collaborate with circuit designers to convert schematics into layouts, ensuring matching, symmetry, shielding, parasitic targets, and reliability constraints are maintained.
Collaborate with PnR and integration teams to resolve top-level DRC/LVS, pin access, boundary, routing, power-grid, and macro-integration issues.
Implement and advance layout methodology, checklists, reusable practices, and quality standards for consistent memory IP delivery.
Collaborate with foundry, CAD, and methodology teams on rule interpretation, deck behavior, waivers, and advanced-node process constraints.
Review layouts, mentor junior engineers, and help raise layout quality and execution rigor across the team.
Key required skills:
Have a BSEE or equivalent experience 10 years of custom IC layout experience, including 5 years in SRAM, memory compiler, or full-custom memory IP layout.
Hands-on participation in advanced CMOS technology initiatives, preferably concentrating on FinFET or GAA nodes at 5nm, 3nm, or smaller dimensions.
Solid grasp of SRAM and memory layout principles.
Extensive experience in Cadence Virtuoso applied to custom layout creation and assessment.
Extensive experience in DRC/LVS debugging using Calibre, ICV, or similar physical verification tools.
Experience with floorplanning, block-level routing, macro assembly, pin planning, boundary/interface management, and top-level physical verification.
Direct familiarity with advanced-node layout limitations and layout-dependent phenomena, including LOD, density/fill, matching, symmetry, shielding, electromigration, IR drop, and DFM or similar expertise.
Ability to work effectively with circuit build, physical build, integration, CAD, and foundry teams.
Clear communication, strong ownership, good judgment, and the ability to mentor other engineers.
Knowledge of layout automation or AI tools is a definite plus.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
