About the Role
This team is designing active and passive Silicon Photonics devices and systems that are at the frontier of the technology and core to Lightmatter products. This job will require diving deep into the physics and working principles of all kinds of device designs, creating test plans, and layouts, analyzing data and experiments and creating models.
Key Responsibilities
- Design high-performance passive and active Silicon Photonics devices with commercial software such as Lumerical, Tidy3D, 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 and close the loop with design and simulations.
Requirements & Tech Stack
- Currently enrolled in a PhD program, specializing in Electrical Engineering, Physics, Photonics, or related fields.
- Good understanding of Silicon Photonics or General Photonics.
- Experience in electro-optic design of silicon photonics components.
- Demonstrate problem-solving skills in problems that do not have obvious solutions.
- Exposure to developing and implementing automated design and analysis using Python scripting.
- Data-driven and analytical; translates numbers into actionable strategies.
- Process-oriented and programmatic: builds structure through processes.
- Excellent written and verbal communication skills.
- Interest in Photonics Design.
- Willingness and curiosity to learn from an exciting team.
Preferred Qualifications
- Experience in design of high speed transceiver systems.
- Work with foundries.
- Exposure to designing PDK Components.
Other Information
- Hourly Rate in USD: $57 — $65 USD.
- Candidates should have capacity to comply with the federally mandated requirements of U.S. export control laws.
