Job summary

Lumilens Inc. is seeking engineers to design high-speed silicon photonic integrated circuits, taking concepts all the way to tapeout and silicon validation.

The role suits PhD graduates through early-career engineers (0–5 years) who want to work on production-bound systems, not just simulations. You will design devices and circuits, perform multi-domain simulations, and collaborate with electronics and packaging teams to bring up and characterize silicon systems.

Qualifications

• Experience in silicon photonics design and optimization.
• Ability to perform multi-domain simulations (EM, circuit, thermal).
• Experience with tapeouts and foundry PDKs.

Responsibilities

• Design and optimize silicon photonic devices and circuits.
• Perform multi-domain simulations to meet targets in EM, circuit, thermal.
• Implement PIC layouts (GDS) using foundry PDKs and support tapeouts.
• Co-design with electronics and packaging teams for CPO/NPO systems.
• Support silicon bring-up and characterization.
• Contribute to design libraries, modeling, and methodology development.

Job description

Role Overview

You will design high-speed silicon photonic integrated circuits operating at the limits of bandwidth and integration, and take them from concept → tapeout → silicon validation.

This role is suitable for strong PhD graduates through early-career engineers (~0–5 years experience) who want to work on real, production-bound systems , not just simulations.

Roles & Responsibilities

• Design and optimize silicon photonic devices and circuits , including:

• Perform multi-domain simulations (EM, circuit, thermal) to meet targets in:

• Implement PIC layouts (GDS) using foundry PDKs and support tapeouts

• Co-design with electronics and packaging teams for CPO/NPO systems:

• Support silicon bring-up and characterization :

• Contribute to design libraries, modeling, and methodology development

Requirements

• Education

• Experience

• Technical Skills

• Implementation Skills

• System Awareness

Nice to Have

• Experience with high-speed devices (>100 GHz bandwidth or equivalent)

• Exposure to CPO/NPO or optical transceiver architectures

• Familiarity with SiPh + III-V integration

• Experience with inverse design / adjoint methods (e.g., Meep)

Why Join Us

• Work on real products at 200G/lane+ , not just research prototypes

• Direct impact on AI infrastructure and hyperscale systems

• Fast iteration cycles from design → silicon → system

• High ownership early in your career

• Comprehensive benefits package including health insurance

• Collaborative environment with world-class engineering and R&D teams
