Photonics Engineer Intern - Summer 2027
$57 USD hourly
Design active and passive silicon photonics components using Lumerical, Tidy3D, and Cadence.
Originally posted 11 November 2026 by the employer.
About the role
This role involves designing active and passive silicon photonics devices and systems core to Lightmatter products. You will analyze device physics, create test plans and layouts, analyze experimental data, and build models.
What you'll do
- Design passive and active silicon photonics devices using commercial software such as Lumerical, Tidy3D, and Cadence.
- Develop automated inverse design of silicon photonic components.
- Develop control algorithms for photonics subsystems for real-world use cases.
- Assess fabrication variability and operational performance of Si photonic components.
- Develop and implement testing and analysis methodology for new and existing silicon photonics devices, including design-for-test, design-for-manufacturing, and design-of-experiments.
- Design and execute model creation for silicon photonics chips and subsystems based on measurement data to close the loop with design and simulations.
What you'll need
- Current enrollment in a PhD program specializing in Electrical Engineering, Physics, Photonics, or related fields.
- Understanding of silicon photonics or general photonics.
- Experience in electro-optic design of silicon photonics components.
- Exposure to developing and implementing automated design and analysis using Python scripting.
Nice to have
- Experience in design of high speed transceiver systems.
- Work with foundries.
- Exposure to designing PDK components.
