• Troubleshoot customer test systems and measurement challenges.
• Serve as the primary technical interface between customers and internal engineering teams.

• Configure, operate, and maintain cryogenic wafer probing systems and associated instrumentation.
• Develop and execute measurement plans for semiconductor and superconducting devices.
• Perform RF, microwave, DC, low-current, and low-noise electrical characterization.
• Integrate test equipment including Vector Network Analyzers (VNAs), Spectrum Analyzers, Signal Generators, Source Measure Units (SMUs), Lock-in Amplifiers, Low-Noise Amplifiers, and Cryogenic instrumentation and temperature controllers.
• Analyze measurement results and provide recommendations to customers and engineering teams.

• Collaborate with product development teams on new applications, features, and customer requirements.
• Generate application notes, technical reports, training materials, and best-practice guides.
• Evaluate emerging measurement techniques and industry trends.
• Provide feedback from customer engagements to influence future product development.

• Conduct customer demonstrations and proof-of-concept testing.
• Support sales with technical experience
• Travel to customer sites to perform application support
• Provide training on tool usage, measurement methodologies, instrumentation, and software workflows.
• Represent the company at conferences, technical workshops, and customer technology reviews.

• Bachelor's degree in electrical engineering, Physics, Applied Physics, or related technical field.
• 5+ years of experience in semiconductor test, RF measurement, cryogenic systems, or related instrumentation.
• Strong understanding of semiconductor device physics and electrical characterization techniques.
• Experience with RF and microwave measurements through at least 18 GHz.
• Experience performing sensitive low-noise and low-current measurements.
• Hands-on experience with automated test systems and data acquisition.
• Strong troubleshooting and analytical skills.
• Excellent written and verbal communication skills.
• Experience operating cryogenic systems below 4 K.
• Experience with superconducting devices, quantum computing hardware, or cryogenic CMOS technologies.
• Familiarity with wafer probing systems and probe card technologies.
• Knowledge of S-parameter measurements, Noise characterization, Time-domain measurements, Device reliability testing, and Cryogenic RF techniques.
• Experience developing automated measurement software using Python, LabVIEW, MATLAB, or similar tools.
• Customer-facing experience in applications engineering, field engineering, or technical consulting.

• Approximately 25% travel, including domestic and international customer installations, training, and support engagements.
