R&D Engineer, Signal Integrity - US-CA-Calabasas, United States
$124,420 - $207,370 USD yearly
Originally posted 29 May 2026 by the employer.
Design and validate high-speed serial interfaces operating at 100G/200G PAM4 and above for test and measurement systems.
About the role
This role involves the design and validation of high speed serial interfaces, including selecting materials, design structures, and methodologies to achieve design specifications and SI margins. The position sits within Keysight Network Test, focusing on high-frequency PCB designs and subsystem solutions for test and measurement products.
What you'll do
- Model and optimize high-frequency PCB, IC packages, substrates, and high-speed digital I/O interconnects operating at 100G/200G PAM4 and above. - Collaborate with system, hardware, board design, and test teams to define hardware requirements and performance needed to satisfy SI requirements. - Identify design structures, geometries, and stackups to satisfy insertion loss, return loss, and SI requirements. - Support and investigate materials and stackups/process in PCB fabrication to meet SI needs. - Collaborate with internal and external supply chain manufacturing partners to develop, deploy, and execute processes and materials. - Work with development, test, and reliability teams on the characterization and qualification of PCBA materials.
What you'll need
- BS or MS degree in Electrical Engineering or equivalent. - Minimum 7+ years of experience (or MS with 5 years) in hardware/circuit and IC package design, high-frequency modeling/optimization, or high-power density design. - Understanding of Electrical Engineering principles, Signal Integrity, RF/Microwave theory, and high frequency circuit design methodologies. - Fluent or experienced in ANSYS HFSS, 3D-Layout, and Polar Instruments. - Familiarity with Allegro. - Experience with semiconductor, packaging, substrates, and printed circuit board technologies, associated materials and copper roughness, manufacturing processes, and design methodologies.
Nice to have
- Understanding/familiarity with PCB design methodologies, processes, and workflows.
