## Description

We are hiring a Principal Electro-Optic Systems Architect. The selected candidate will partner with external facing teams at Lightmatter and internal engineering teams to deliver groundbreaking products to the market. In this role, you will be responsible for ensuring that Passage's electrical-optical-electrical links are performant and meet customer requirements. You will engage with our cross-disciplinary engineering teams to model and analyze solutions. You may also test and measure prototypes to validate the models. This role requires a solid understanding of leading-edge CMOS, advanced silicon photonics, high-speed (40+ GHz) electro-optic interfaces, and 3D integration. The role also requires creativity, analytical skills, and clear communication skills. You are encouraged to represent the company at technical conferences as an example of our technical leadership., * Be the architecture owner of the electro-optic performance of a Lightmatter's Passage product.

 * Electro-optic system modeling using Cadence photonics-analog simulators (Verilog-A, Spectre, Virtuoso), VPI Photonics, and Keysight ADS
 * Design the end-to-end electrical-optical-electrical system-level link to meet the customer requirements.
 * Co-design the analog and photonic devices with the engineering design teams based on the end-to-end simulation results.
 * Validate the models by designing high-speed RF experiments, conducting proof-of-concept experiments, and analyzing existing data.
 * Author, review, and validate architectural specifications.
 * Collaborate with the product team to develop the technological and product roadmap in the context of the industry trends
 * Identify possible pitfalls or difficulties, as well as mitigation strategies, around the execution of the proposed architecture.
