Kerja Sepenuh Masa, Senior Silicon Photonics Engineer di Lumilens - Maukerja

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:

  • High-speed modulators (MZI, ring, advanced structures)

  • Photodetectors and receiver building blocks

  • Passive components (couplers, filters, routing)

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

  • Bandwidth (200G/lane+)

  • Insertion loss, extinction ratio, efficiency

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

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

  • RF effects, parasitics, signal integrity, and thermal constraints

• Support silicon bring-up and characterization:

  • Correlate measurement vs simulation

  • Drive design iterations and improvements

• Contribute to design libraries, modeling, and methodology development

Requirements

• Education

  • PhD in Electrical Engineering, Physics, or related field (silicon photonics or closely related area)

• Experience

  • 0–5 years of relevant experience (including fresh PhD graduates)

• Technical Skills

  • Experience in design and simulation of silicon photonic devices or PICs

  • Strong understanding of guided-wave optics and device physics

  • Familiarity with tools such as Lumerical, COMSOL, or equivalent

• Implementation Skills

  • Exposure to PIC layout and tapeout flows (PDK, DRC/LVS)

• System Awareness

  • Basic understanding of optical communication systems and/or RF effects

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
