Responsibilities

• Develop and execute characterization test plans for RF semiconductor devices.
• Perform RF measurements including S-parameters, load pull, pulsed RF, power sweep, harmonics, ACPR, and modulation testing.
• Operate, calibrate, and maintain RF test equipment including vector network analyzers, spectrum analyzers, signal generators, oscilloscopes, power meters, source measure units, and load pull systems.
• Analyze measurement data and prepare technical reports summarizing device performance.
• Troubleshoot hardware, software, instrumentation, and measurement-related issues.
• Develop and maintain automated test and data analysis tools using Python, Excel VBA, MATLAB, or similar programming languages.
• Support on-wafer and fixtured RF characterization activities.
• Collaborate with design and product engineering teams to investigate device performance and resolve technical issues.
• Document test procedures, calibration methods, and characterization results.
• Assist in the development of new measurement techniques, test fixtures, and laboratory capabilities.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Electronics Engineering, or related field.
• 5+ years of experience in RF test engineering, device characterization, or semiconductor product development.
• Strong understanding of RF fundamentals including S-parameters, gain compression, load pull, efficiency, harmonics, ACPR, and modulation measurements.
• Hands-on experience with RF test instrumentation including vector network analyzers, spectrum analyzers, signal generators, power meters, oscilloscopes, and power supplies.
• Experience with RF load pull systems and power amplifier characterization.
• Experience developing automated test solutions and data analysis tools using Python, Excel VBA, MATLAB, or similar tools.
• Strong analytical and problem-solving skills.
• Excellent verbal and written communication skills.
• Ability to work effectively in a team environment while managing assignments with limited supervision.

Preferred Qualifications

• Experience with RF semiconductor technologies such as GaN, GaAs, SOI, or silicon-based devices.
• Experience with on-wafer RF measurements and calibration techniques.
• Familiarity with pulsed IV characterization and nonlinear device testing.
• Experience working in a semiconductor characterization or product development laboratory.
• Knowledge of statistical data analysis and database-driven measurement systems.
