Senior Signal Integrity Engineer — High‑Speed Data Center

Amphenol Communications Solutions; Yocumtown (PA); On-site; USD 120,000 - 150,000; Full time

Job summary

Amphenol Communications Solutions (ACS), a division of Amphenol Corporation, seeks a Senior Signal Integrity Engineer in Valley Green, PA to design, characterize, and qualify high‑speed RF coaxial and twinaxial cable assemblies for data center interconnects.

The role blends hands-on measurements (VNA, TDR, BERT) with simulations and cross‑functional collaboration to meet electrical performance targets at data rates up to 224G/448G PAM4.

Qualifications

• Hands-on measurements with VNA, TDR/TDT, and BERT equipment.
• Strong understanding of transmission line theory and high-speed channel design (112G/224G)

Responsibilities

• Perform S-parameter measurements (VNA) and TDR on coax and twinax cable assemblies to characterize insertion loss, return loss, crosstalk, and impedance discontinuities.
• Conduct BERT-based bit‑error rate testing and eye-diagram analysis to validate SI margins across interfaces.
• Support 3D EM simulation (HFSS, CST, or similar) to correlate simulated vs. measured performance.
• Drive root‑cause analysis on SI failures and recommend design or process corrective actions.
• Collaborate with mechanical and manufacturing engineering on cable construction, termination geometry, and connector interfaces.
• Support qualification test plans and re‑qualification workflows, including differential pair testing and reliability studies.
• Develop and maintain test fixtures, automation scripts, and data analysis pipelines for high-throughput characterization.
• Present findings and design recommendations to internal stakeholders and customers, including executive-level summaries of qualification status and risk.
• Stay current with industry standards (IEEE 802.3, OIF-CEI) and channel modeling methodologies for next-gen data rates.
