Who this role is best for

Strong fit for hands-on engineers who validate signal integrity and collaborate across teams, with expertise in high-speed interconnects and a background in electrical or computer engineering.

Best fit for

Hands-on engineers with experience in high-speed interconnect validation and cross-functional collaboration
— “Validate signal integrity (SI) and power integrity (PI) for advanced compute platforms, focusing on hands-on measurement, electrical compliance, troubleshooting, and simulation correlation.”
Candidates with a background in electrical or computer engineering and a focus on SI/PI fundamentals
— “Bachelor's or master's degree in Electrical Engineering, Computer Engineering, or a related field.”
Individuals who can design and execute experiments for board-to-board and rack-level interconnects
— “Develop measurement plans and design of experiments (DOE) for board-to-board, cable, backplane, blade-, and rack-level interconnects.”

Things to consider

The role requires a strong emphasis on measurement automation and simulation correlation, which may demand advanced technical skills.
— “Correlate measurements with simulations and troubleshoot issues with silicon, package, board, and system teams”
Candidates should be prepared for a mix of hardware testing and detailed technical reporting.
— “Prepare validation and compliance reports covering methods, pass/fail results, performance margins, findings, and recommendations.”

How to stand out

Highlight experience with VNAs, TDRs, and high-speed oscilloscopes in your resume and interviews.
— “Hands-on expertise with vector network analyzers (VNAs), including performance network analyzers (PNAs); time-domain reflectometers (TDRs); bit error rate testers (BERTs); and high-speed oscilloscopes.”
Showcase your experience with PCIe 4/5/6, Ethernet, DDR, and SerDes links in your technical background.
— “Peripheral Component Interconnect Express (PCIe) generations 4/5/6, Ethernet, Double Data Rate (DDR) memory, serializer/deserializer (SerDes) links”

Signal Integrity Measurement Engineer
Location: Austin
About the Role
Validate signal integrity (SI) and power integrity (PI) for advanced compute platforms, focusing on hands-on measurement, electrical compliance, troubleshooting, and simulation correlation.
Key Responsibilities
Develop measurement plans and design of experiments (DOE) for board-to-board, cable, backplane, blade-, and rack-level interconnects.
Measure scattering parameters (S-parameters), insertion loss, return loss, impedance, crosstalk, eye diagrams, jitter, timing margins, and bit error rates.
Design printed circuit board (PCB) test fixtures; perform calibration, de-embedding, and electrical compliance testing against interface specifications and customer requirements.
Correlate measurements with simulations and troubleshoot issues with silicon, package, board, and system teams, interconnect vendors, and original design manufacturers (ODMs).
Prepare validation and compliance reports covering methods, pass/fail results, performance margins, findings, and recommendations.
Required Qualifications
Hands-on expertise with vector network analyzers (VNAs), including performance network analyzers (PNAs); time-domain reflectometers (TDRs); bit error rate testers (BERTs); and high-speed oscilloscopes.
Strong SI/PI fundamentals and experience with fixture characterization, repeatable measurements, DOE, and electrical compliance testing.
Strong written and verbal communication skills for technical reporting and cross-functional collaboration.
Bachelor's or master's degree in Electrical Engineering, Computer Engineering, or a related field.
Preferred Qualifications
Data center or hyperscale hardware experience; Python or MATLAB for measurement automation and analysis; familiarity with simulation tools and thermal or mechanical effects on SI/PI.
Tools / Technologies
Peripheral Component Interconnect Express (PCIe) generations 4/5/6, Ethernet, Double Data Rate (DDR) memory, serializer/deserializer (SerDes) links, Serial Peripheral Interface (SPI), and Inter-Integrated Circuit (I²C).
