Staff High-Speed I/O Test Engineer

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.

Hands-on experience in the characterization and testing of silicon photonics components and circuits (e.g., tunable lasers, power meters, polarization synthesizers, OBR/OVA).

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.

We are looking for an engineer with a proven track record of testing real-world industry products.

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.
