About the Project We are seeking an experienced Signal Integrity (SI), Power Integrity (PI) and Telecom Timing Validation Consultant to support validation and compliance activities for an advanced networking platform targeting telecom, vRAN and time-sensitive networking applications. The project includes validation of: 1G / 10G / 25G Ethernet interfaces SyncE (Synchronous Ethernet) IEEE 1588 PTP GNSS-disciplined timing DPLL and clock-generation subsystems OCXO holdover architectures PPS and ePPS interfaces Telecom synchronization compliance, including G.8262 and G.8262.1

Key Responsibilities Signal Integrity Validation

• Execute Ethernet compliance and characterization testing at 1G, 10G and 25G.
• Perform eye-diagram analysis and jitter decomposition.
• Characterize channel performance, insertion loss, return loss and crosstalk.
• Support debugging of PHY, SerDes and recovered-clock issues.
• Validate DAC, AOC, optical and breakout-cable configurations.

Telecom Timing Validation

• Execute and document SyncE clock characterization.
• Perform MTIE and TDEV measurements.
• Run wander generation and tolerance testing.
• Perform noise-transfer and holdover characterization.
• Validate reference switching and PPS/ePPS timing.
• Characterize DPLL and OCXO performance.

Laboratory Execution and Reporting

• Develop and execute compliance procedures and automated data capture.
• Produce test reports, evidence packages and calibration traceability records.
• Maintain complete audit-ready evidence for telecom timing compliance programs.

Essential Experience Must Have

• 10+ years of high-speed digital hardware validation experience.
• Strong SI background with Ethernet interfaces from 1G to 25G.
• Extensive jitter analysis, eye-diagram and compliance-testing expertise.
• Experience operating high-end oscilloscopes and BERT equipment.
• Strong, independent laboratory debugging skills.
