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, working alongside a senior layout engineer and partnering with design teams across the US, India, and Singapore.

Responsibilities

• Own layout for assigned analog and mixed-signal blocks: device placement, matching and symmetry, shielding, guard rings, and routing, from floorplan through to clean sign-off.

• Execute parasitic-aware layout — build to the constraints given by designers, run ext
