## Description

In this role, you will be responsible for the advanced platform-level validation of next-generation Lightmatter products. You will be expected to develop product-specific platform validation test plans for products from development to high-volume manufacturing. It also involves engaging with silicon design, digital verification, software, packaging, and system platform engineering teams to influence the definition of the product and to leverage the capabilities of the ecosystem from a platform validation perspective. You will be developing validation capabilities, tools, and platform-focused tests in Lightmatter. Part of the role is expected to support customer deployment and related technical issues., * Own development of overall platform-level post-silicon validation strategies and plans for our highly integrated photonics-based AI platform, our photonics chiplet communication fabric and Laser module.

 * Define validation plan for platform-level qualification and high-volume manufacturing.
 * Partner and influence design teams (hardware, software) during pre-silicon targets to ensure Pre-Si simulation meets specifications and milestone criteria. As needed, work with the design team to include validation hooks, telemetry sensors etc on Si, test vehicles and reference systems for comprehensive post-Si validation and monitoring.
 * Setting up validation capabilities, automation, and executing validation in Lightmatter facilities.
