Senior Test Development Engineer

About the role

Development of H/W and S/W for RF projects including Broad Band, Base Station, and RF Beam Forming. This role involves demonstrating strong expertise in RF ATE platforms such as DMDX, LTX-AC, or equivalent RF ATE, including test program development, debug, optimization, and production deployment.

Key responsibilities

• Demonstrate strong expertise in RF ATE platforms such as DMDX, LTX-AC, or equivalent RF ATE, including test program development, debug, optimization, and production deployment
• Collaborate with RF design teams to drive Design-for-Test (DFT) requirements, improve testability, and support product transition from design validation through high-volume manufacturing
• Apply in-depth knowledge of RF and microwave measurements, including S-parameters, gain, output power, insertion/return loss, noise figure, harmonics, linearity, phase noise, EVM, and calibration methodologies to correlate on RF loss
• Demonstrate proficiency in the operation, troubleshooting, and correlation of RF test instrumentation, including Vector Network Analyzers (VNA), Spectrum Analyzers, Signal Generators, Power Meters, Noise Figure Analyzers, Oscilloscopes, and related measurement systems
• Lead cross-functional and global project teams to drive test development initiatives, align technical requirements, manage project execution, and ensure successful product introduction and manufacturing readiness
• Develop and maintain automated test solutions using Python, C#, LabVIEW, MATLAB, or similar programming languages to improve test coverage, measurement repeatability, manufacturing yield, and production efficiency

About you

• Bachelor's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related discipline, with a strong understanding of RF, microwave, and semiconductor test technologies
• 5+ years of hands-on experience in RF product development and test engineering, including RF test hardware design, fixture development, product characterization, qualification, and production test implementation from concept through production release
• Experience with Cohu LTX-ac tester platform / Cohu LTX-Pax and DMDX tester platforms
• Advanced understanding of RF test items such as S-parameters, gain, output power, insertion/return loss, noise figure, harmonics, linearity, phase noise, EVM
• Knowledge to control SA (Spectrum Analyzer), VNA (Vector Network Analyzer), PM (Power Meter)
• Strong technical ability and knowledge of test instrumentation devices such as signal generators, oscilloscopes, spectrum analyzer, switching, frequency counters and power meters
