Signal Integrity Test Engineer (CBS)

The Signal Integrity Test Engineer is responsible for working in collaboration with Design Engineering, Manufacturing, and Quality teams to own the development, deployment, and sustaining support of high-speed signal integrity test systems for cable assemblies and interconnect products — with particular emphasis on bit-error-rate performance and PRBS-based stress testing.

Responsibilities:

• Define robust production test methods, limits, calibration requirements, correlation plans, and acceptance criteria for VNA, TDR, BERT, and oscilloscope-based measurements.
• Perform empirical signal integrity evaluations of cables, connectors, and interconnect assemblies, correlating production measurements with customer data and reference equipment to ensure repeatable and defensible test outcomes.
• Provide expert troubleshooting for electrical and signal-integrity issues, diagnosing pattern-lock failures, loss of signal, lane-specific errors, jitter sensitivity, crosstalk, insertion-loss impacts, fixture degradation, and correlation gaps between test platforms.
• Establish preventive maintenance, calibration, verification, and spare-parts programs for SI test assets; anticipate obsolescence and capacity needs and provide technical inputs for capital planning.
• Collaborate with Process Engineering and Quality to improve FPY, RTY, scrap, retest rate, downtime, and test escape performance, analyzing BER by lane, data rate, pattern, fixture, and tester to optimize screening limits.
• Create and maintain test specifications, work instructions, validation reports, correlation studies, equipment standards, and change-control records; train technicians and engineers on standardized test practices.
• Support new product introductions, pilot builds, equipment installations, process validations, customer investigations, and global manufacturing-site deployments.
• Prepare status reports and present test performance updates to leadership.
