About the role

You will be focused on validating and architecting package and system-level test strategies for high-speed I/O interfaces on Lightmatter's novel product line.
In this role, you will be responsible for setting up and executing high-speed electrical characterization, driving link bring-ups, and stress-testing I/Os in system environments.
You will work closely with cross-functional teams to transition these technologies into high-volume manufacturing.

Work directly with architecture, signal integrity, and silicon design teams to understand the technology and conceptualize characterization and test techniques targeting product manufacturing.
Architect test concepts, test platforms, and design-for-test rules, providing critical feedback during the technology concept phase.
Develop Python-based test software and scripts to automate lab measurements, test execution, data analysis, and parameter extraction.
Define and develop stress testing methodologies to identify design operating limits of serial I/Os post-system integration.

6+ years of industry experience in transceiver, SerDes, or high-speed link test development on products
Experience in test system automation and data processing using Python.
Ability to convey complex technical concepts to both technical and non-technical stakeholders.

Hands-on experience in the characterization and testing of silicon photonics components and circuits (e.g., tunable lasers, power meters, polarization synthesizers, OBR/OVA).
Understanding of Silicon Photonics components and optical testing methodologies.
Knowledge of industry specifications such as IEEE 802.3, OIF, PCIe, or USB4.
Ph.D. with 2+ years of relevant industry experience.
