Lightmatter Staff High-Speed I/O Test Engineer at Lightmatter focuses on validating and architecting package and system-level test strategies for high-speed I/O interfaces. Responsibilities include high-speed electrical characterization, link bring-ups, and stress-testing I/Os in system environments.

Responsibilities

Execute high-speed serial I/O characterization and validation across multiple platforms for Lightmatter products.
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.
Set up and operate a wide range of high-speed lab equipment, including oscilloscopes, BERTs, AWGs, TDRs, and VNAs/PNAs.
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.
Troubleshoot and triage complex issues with compliance test hardware, fixtures, software, and the Device Under Test (DUT).
Work with vendors to specify and procure state-of-the-art test equipment.

Qualification

Master’s in Electrical EngineeringPh

Required

Master’s in Electrical Engineering, Computer Engineering, or a related field.
6+ years of industry experience in transceiver, SerDes, or high-speed link test development on products
Extensive hands-on lab experience and familiarity with high-speed equipment, including oscilloscopes, BERTs, PPGs, VNAs, and spectrum analyzers.
Strong familiarity with high-speed interfaces and analog building blocks (e.g., PLL, CDR, CTLE, DFE, FFE, and FEC).
Experience in test system automation and data processing using Python.
Strong analytical and debugging skills to identify and solve hardware and signal integrity issues during the testing process.
Ability to convey complex technical concepts to both technical and non-technical stakeholders.

Preferred

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.
Deep knowledge of system-level SerDes design and channel analysis, including understanding insertion loss, return loss, crosstalk, and link training algorithms.
Knowledge of industry specifications such as IEEE 802.3, OIF, PCIe, or USB4.
Ph.D. with 2+ years of relevant industry experience.
