Staff High-Speed I/O Test Engineer

Join Lightmatter as a Staff High-Speed I/O Test Engineer, where you will validate and architect test strategies for high-speed I/O interfaces. You will work closely with cross-functional teams, execute high-speed serial I/O characterization, and develop test software. This role offers a generous benefits package, including a commuter benefit, 401(K), and a generous vacation policy.

• Execute high-speed serial I/O characterization and validation across multiple platforms for Lightmatter products.
• 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.
• 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
• 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
• 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)
• Master’s in Electrical Engineering, Computer Engineering, or a related field
• Ph.D. with 2+ years of relevant industry experience
• Knowledge of industry specifications such as IEEE 802.3, OIF, PCIe, or USB4
• Deep knowledge of system-level SerDes design and channel analysis, including understanding insertion loss, return loss, crosstalk, and link training algorithms
• Understanding of Silicon Photonics components and optical testing methodologies
• Hands-on experience in the characterization and testing of silicon photonics components and circuits (e.g., tunable lasers, power meters, polarization synthesizers, OBR/OVA)
