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

The role

Lumilens builds optical interconnect for AI data centers: silicon photonics, mixed-signal ICs, electrical-optical interposers, and the systems around them. Our silicon ships in production AI clusters today, and volume is climbing fast.

You will own layout for our electronic ICs (EICs) and photonic ICs (PICs). These are high-speed analog blocks where the layout is the design: a parasitic you did not anticipate, a return path you did not control, or a current density you did not check will cost the part its margin.

You will also support photonic IC (PIC) layout as our schedule demands, and own the integration of electronic and photonic dies as they come together.

Singapore puts you close to the assembly and test supply chain we depend on, partnering with design teams across the US, India, and Singapore. You will be the senior layout voice on the ground here.

Responsibilities

Block and top-level layout

• Own floorplan and layout for high-speed analog and mixed-signal blocks: TIAs, drivers, SerDes front ends, PLL and clocking, references and bias.

• Execute device-level matching an
