About this RoleYou 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. We are looking for an engineer with a proven track record of testing real-world industry products. You will be part of a growing interdisciplinary team with a lot of opportunities to learn and make a big impact.
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.
Requirements- 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 Qualifications- 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.
