• Experience supporting prototype development, validation testing, and New Product Introduction (NPI) activities.
• Experience working in laboratory and/or cleanroom environments with appropriate safety and ESD controls.

Education Requirement:

• 6+ years of related hands‑on experience supporting electrical, RF, electromechanical, or semiconductor equipment in a lab, manufacturing, or R&D environment.
• Associate’s degree, technical certificate, diploma, or higher education in electronics, RF engineering, electrical engineering, or a related technical field.

Responsibilities:

• Perform advanced testing, checkout, calibration, and troubleshooting of RF, electrical, electromechanical, and vacuum systems using schematics, diagrams, layouts, and defined test plans.
• Assemble, configure, test, and diagnose high‑power, high‑voltage RF subsystems, including RF matching networks, sensors, power delivery components, and associated electronics.
• Conduct system‑level and PCBA‑level troubleshooting, fault isolation, and root‑cause analysis for electrical, mechanical, and RF‑related failures.
• Utilize electronic and RF test equipment such as VNAs, oscilloscopes, signal generators, power meters, DMMs, and specialized diagnostic tools to support characterization and debug.
• Inspect materials, components, and assemblies for defects; perform measurements using precision instruments, microscopes, and standard lab procedures.
• Support prototype hardware bring‑up, integration, modification, and validation in close collaboration with development engineers.
• Assist engineering teams with experimental setups, data collection, and validation testing for concept, feasibility, and NPI activities.
• Perform component‑level rework, repair, and replacement, including soldering and SMD rework, in accordance with lab and ESD standards.
• Maintain accurate documentation including test results, procedures, build records, and troubleshooting notes.
