About the role
We are seeking a Senior Signal Integrity Engineer to develop, validate, and optimize high-speed signaling solutions across blade- and rack-level architectures for advanced compute platforms. This role sits at the intersection of silicon, package, interconnect, board, and system design , with a strong emphasis on hands-on measurement, simulation correlation, and cross-functional technical communication.
What they're looking for
- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field
- Strong experience in signal integrity for high-speed digital systems
- Hands-on measurement expertise using VNAs, TDRs, BERTs, and high-speed oscilloscopes
- Experience measuring and analyzing S-parameters, impedance profiles, eye diagrams, jitter, timing margins, insertion loss, return loss, and crosstalk
- Knowledge of high-speed interfaces such as PCIe Gen4/5/6, Ethernet, DDR, SerDes , and related I/O technologies
- Experience with SI/PI simulation tools such as HFSS, ADS, Sigrity, CST, SPICE , or equivalent
