Senior High-Speed Photonics Design Engineer (200 Gbit/s)

Neara; Santa Clara (CA); Hybrid; USD 225,000 - 305,000; Full time

Job summary

OpenLight is seeking a Principal High-Speed Photonics Design Engineer to lead the development and integration of high-speed optoelectronic devices on a silicon-IIIV platform. You will design modulators and detectors, simulate with industry tools, and collaborate across fabrication, packaging, and systems teams to validate devices and contribute to OpenLight’s PDK models.

The role requires a PhD with 10+ years in Si-Ge/III-V modulators, strong RF device physics knowledge, and hands-on experience

Qualifications

• PhD in Electrical Engineering, Materials, Physics, or related field.
• 10+ years in designing Si-Ge and/or III-V high-speed modulators/detectors for transceivers.
• Strong background in semiconductor high-speed device physics (SiGe/III-V).
• Hands-on experience with high-speed device simulations and circuit design tools (e.g., Ansys HFSS, CST, ADS, Sentaurus TCAD, Crosslight).
• Experience with RF characterization of photonic devices (transceivers a plus).
• Knowledge of fabrication processes for semiconductors.
• Strong analytical and problem-solving skills in a fast-paced, collaborative environment.
• Excellent written and verbal communication for technical documentation.

Responsibilities

• Design and optimize high-speed III-V optical modulators and detectors (EAM, MZI, IIIV PIN, UTC).
• Analyze results vs simulations; refine designs and generate compact models for PDK.
• Publish and maintain equivalent circuit models; document OpenLight PDK materials and models.
• Collaborate with layout/fabrication to define masks and process flows for devices.
• Work with system engineers to integrate modulators into high-speed validation hardware.
• Support test engineers with high-speed device test development and characterization.
• Stay current with silicon photonics and III-V high-speed interconnect trends.
• Publish in journals/conferences and contribute ideas for patents.
