IC Layout Engineer – Optical Engine Silicon
Singapore. Posted a month ago
The role
You will own the layout for electronic and photonic integrated circuits. This includes device placement, routing high-speed signal paths, and managing the integration of electronic and photonic dies.
What you will do
- Own layout for assigned analog and mixed-signal blocks including placement, matching, shielding, and routing.
- Execute parasitic-aware layout and run extraction.
- Route high-speed signal paths with attention to impedance, coupling, and return paths.
- Lay out passive and electromagnetic structures under senior direction.
- Run and close DRC, LVS, antenna, and density checks.
- Support electromigration and IR drop analysis.
- Support top-level assembly and chip finishing activities through tape out.
- Support PIC layout including waveguide and curvilinear structures.
- Lay out photonic components and waveguide routing.
- Run photonics-specific verification and clean GDS stream-out for tape out.
Required qualifications
- Diploma, BS, or MS in Electrical or Electronics Engineering, or equivalent hands-on layout experience.
- 1–3 years in custom analog, RF, or mixed-signal IC layout.
- At least one tapeout contributed to through to silicon.
- Solid working experience with Cadence Virtuoso, including Layout XL and constraint-driven flows.
- Parasitic awareness in practice.
- Fundamentals in electromigration and IR drop.
- Fundamentals in electromagnetics for on-chip structures.
- Physical verification experience: Calibre or PVS DRC/LVS, and parasitic extraction with QRC, StarRC, or equivalent.
- Some scripting for layout automation: SKILL, Python, or both.
- Willingness to overlap with US and India hours during tape out crunch.
Nice to have
- SiGe BiCMOS layout experience
- Advanced FinFET CMOS layout at 7nm and below
- Photonic IC layout exposure
- Experience with parametric photonic cells (PCells) in Virtuoso SKILL or Python-based photonic layout tools
- Familiarity with silicon photonics building blocks
- Exposure to 2.5D and 3D integration, interposers, or micro-bump and copper pillar arrays
- Layout on optical front ends specifically
