Senior Signal Integrity Engineer - High-Speed Interconnects

Amphenol Corporation; Yocumtown (PA); On-site; USD 100,000 - 140,000; Full time

Job summary

Amphenol Communications Solutions, a division of Amphenol Corporation, seeks a Senior Signal Integrity Engineer in Raleigh, NC to design and qualify high-speed RF interconnects for data center and networking applications. You will work hands-on with VNA, TDR, and BERT, plus EM simulations to ensure electrical performance at 224G/448G PAM4-like relevance.

You will collaborate across mechanical and manufacturing teams on terminations, cable construction, and interfaces, while developing automation

Qualifications

• B.S. or M.S. in Electrical Engineering or related field.
• 3+ years of signal integrity, RF/microwave, or high-speed interconnect experience.
• Hands-on with VNA, TDR/TDT, and BERT test equipment.
• Strong knowledge of transmission line theory and high-speed channel design (112G/224G NRZ/PAM4).

Responsibilities

• Perform S-parameter measurements (VNA) and TDR on coax and twinax assemblies to characterize insertion loss, return loss, crosstalk, and impedance discontinuities.
• Conduct BERT-based BER testing and eye-diagram analysis to validate SI margins across interfaces.
• Support 3D EM simulation (HFSS, CST, or equivalent) of terminations and interfaces to correlate with measurements.
• Lead root-cause analysis on SI failures and recommend design or process corrective actions.
• Collaborate with mechanical/manufacturing on cable construction, termination geometry, and mating interfaces.
• Support qualification and re-qualification tests, including differential pair testing and reliability studies.
• Develop test fixtures, automation scripts, and data pipelines (Python/MATLAB) for high-throughput characterization.
• Present findings and design recommendations to internal stakeholders and customers.
• Stay updated with IEEE 802.3, OIF-CEI standards and channel modeling for next-gen data rates.
