Senior/Staff/Principal IC Layout Engineer – Optical Engine Silicon

The role

You will own the layout for electronic and photonic integrated circuits. You will manage floorplans, high-speed signal routing, and chip finishing for high-speed analog and mixed-signal blocks.

What you will do

• Own floorplan and layout for high-speed analog and mixed-signal blocks
• Execute device-level matching and symmetry
• Route high-speed signal paths with control over impedance, coupling, and return paths
• Lay out passive and electromagnetic structures
• Own chip finishing including pad ring, bump and pillar maps, seal ring, density fill, and top-level assembly
• Drive parasitic-aware layout through iteration with designers
• Own electromigration and IR drop closure
• Take blocks through DRC, LVS, antenna, DFM, and ESD and latch-up checks to sign-off
• Support PIC layout including waveguide and curvilinear structures
• Own the EIC-PIC integration

Required qualifications

• Diploma, BS, or MS in Electrical or Electronics Engineering, or equivalent hands-on layout experience
• 8+ years in custom analog, RF, or high-speed mixed-signal IC layout
• Multiple tape outs seen through to silicon
• Expert-level Cadence Virtuoso, including Layout XL and constraint-driven flows
• Deep parasitic awareness
• Working command of electromigration and IR drop fundamentals
• Electromagnetics fundamentals for on-chip structures
• Physical verification fluency: Calibre or PVS DRC/LVS, and parasitic extraction with QRC, StarRC, or equivalent

Nice to have

• SiGe BiCMOS layout experience
• Advanced FinFET CMOS layout at 7nm and below
• Photonic IC layout exposure
• Hands-on silicon photonics layout on a foundry platform
• Understanding of how layout drives photonic performance
• 2.5D and 3D integration, interposers, micro-bump and copper pillar arrays, and co-packaged optics assemblies
• Layout for optical front ends specifically
• Experience standing up layout methodology for a product line in its first generation
• Scripting for layout automation — SKILL, Python, or both
