Job summary

MatX is seeking a hands-on SIPI Engineer to own electrical characterization of high-speed SerDes interfaces and PDN on AI accelerator compute systems. You will build scalable test automation and collaborate with SIPI engineers and board designers from concept to production.

The role requires 5–10 years hardware characterization, a degree in Electrical Engineering, and strong knowledge of SerDes, impedance, and PDN design.

Qualifications

• 5–10 years of industry experience in hardware characterization, SI/PI engineering.
• Bachelor's degree or higher in Electrical Engineering; advanced degree a plus.
• Deep understanding of high-speed SerDes architecture and operation — PHY layer fundamentals, equalization, jitter decomposition, and link margin analysis.
• Strong grasp of transmission line theory — wave propagation, impedance matching, reflections, skin effect, and dielectric loss.
• Hands‑on proficiency with lab equipment and test automation scripting in Python (preferred).

Responsibilities

• Characterize high-speed SerDes interfaces (PCIe, Ethernet, custom protocols) including BER testing, eye diagram analysis, and PVT characterization.
• Tune and optimize SerDes Tx and Rx equalization settings.
• Perform channel characterization including insertion loss, return loss, and crosstalk measurements using VNA and TDR.
• Develop and execute correlation methodologies to align simulation predictions with measured results; drive feedback loops to improve modeling accuracy.
• Measure and analyze high-current power rail transient noise and dynamic voltage droop on complex accelerator power delivery networks.
