About the role

As a Laboratory Service Engineer 3 – RF Systems, you will support and advance RF and plasma technology development in an R&D lab environment. You will work hands-on with high-power RF subsystems, vacuum hardware, and prototype semiconductor equipment used in etch and deposition applications.

What you'll do

- Perform preventive and corrective maintenance, troubleshooting, upgrades, and calibration of RF, electrical, electromechanical, and vacuum equipment in an R&D laboratory. - Assemble, test, calibrate, and diagnose high-power, high-voltage RF subsystems, including RF matching networks, sensors, and associated electronics. - Conduct system-level to PCBA-level failure analysis, including board-level validation, functional testing, and SMD rework. - Utilize laboratory instrumentation including VNAs, oscilloscopes, power meters, and digital multimeters to support RF characterization and troubleshooting. - Diagnose and repair mechanical, electrical, fluidic, and vacuum-based subsystems used in semiconductor processing equipment. - Support prototype equipment installation, bring-up, and validation while developing procedures, test plans, and technical documentation.

What you'll need

- Bachelor’s degree in Electronics, Electrical Engineering, or a related technical field with 2+ years of relevant experience; or an Associate’s degree in a technical field (electronics, RF, or equivalent) or equivalent military training with 4+ years of relevant hands-on experience; or equivalent industry experience supporting RF, electrical, or semiconductor equipment in an R&D or lab environment. - Hands-on experience troubleshooting electrical, electromechanical, or vacuum equipment. - Experience with RF subsystems or laboratory instrumentation.

Nice to have

- Strong hands-on experience with high-power RF subsystems, RF matching networks, sensors, and calibration techniques. - Proven ability to troubleshoot complex electrical, electromechanical, fluidic, and vacuum systems at both system and board level. - Proficiency with lab and test equipment including VNAs, oscilloscopes, power meters, DMMs, and related RF instrumentation. - Experience performing board-level debug, component-level rework, and root-cause failure analysis. - Familiarity with semiconductor capital equipment, RF power delivery systems, or plasma processing tools. - Experience supporting prototype development, validation testing, and New Product Introduction (NPI) activities. - Experience managing lab assets, calibration schedules, and engineering testbeds.
