Cold Test Technician; RF​/Electronics

Build Mission-Critical RF Systems That Power Aerospace and Defense

Join Microwave Power Products as a Cold Test Technician (Radio Frequency/Electronics) and play a key role in preparing high-performance vacuum electronic devices for final manufacturing production and electrical testing. This hands‑on role combines precision mechanical assembly, diagnostic measurement, and technical problem‑solving in a collaborative manufacturing environment.

For over 70 years, Microwave Power Products (MPP) has designed and manufactured RF and microwave technologies used in aerospace, defense, medical, and scientific applications. Our products support mission‑critical systems where reliability, precision, and performance matter most.

Located in Palo Alto, California, MPP joined Trans Digm Group (NYSE: TDG) in 2024, providing the stability and resources of a global aerospace organization while maintaining our fast‑moving, team‑focused culture. We offer hands‑on technical careers, opportunities to grow specialized skills, and the chance to work alongside experienced engineers and technicians building advanced hardware.

Cold Test Technicians support the klystron manufacturing process by assembling, inspecting, measuring, and verifying subassemblies and full units prior to high‑power electrical testing. This role focuses on ensuring mechanical integrity, alignment, vacuum readiness, and preliminary electrical characteristics of complex RF hardware.

The technician works with precision instruments and diagnostic equipment while collaborating closely with engineering, quality, and production teams to identify discrepancies and ensure product readiness. This position requires strong attention to detail, technical judgment, and comfort working with both mechanical assemblies and electronic test equipment.

• Assemble, configure, and prepare klystron subassemblies and full units using engineering drawings, schematics, and manufacturing documentation.
• Perform cold testing and verification activities including dimensional checks, continuity testing, vacuum integrity verification, alignment validation, and mechanical fit assessments prior to high‑voltage or RF testing.
• Operate diagnostic and measurement equipment such as network analyzers, oscilloscopes, RF signal measurement instruments, gauges, and precision torque tools to evaluate hardware condition and readiness.
• Interpret test results, identify discrepancies, and collaborate with engineering and manufacturing teams to troubleshoot and resolve issues.
• Record inspection data, measurements, and part traceability accurately within manufacturing documentation or digital systems.
• Handle, move, and position production hardware using carts, fixtures, cranes, or lifting devices while maintaining equipment safety and product integrity.
• Support contamination control, cleanroom practices, and safety protocols associated with high‑value vacuum electronic hardware.
• Assist with evaluation of non‑conforming or returned hardware and support root cause investigations as needed.
• Collaborate with engineering and quality teams to troubleshoot and resolve build or test discrepancies.
• Maintain organized work areas, tools, and equipment to support production efficiency and quality standards.
• Contribute to continuous improvement initiatives related to assembly, testing, and manufacturing processes.
• Develop technical knowledge across products, RF systems, and manufacturing equipment.
• Perform other operational and production duties as assigned.

• Typically 3‑5 years of experience in electro‑mechanical assembly, electronics maintenance, RF systems, military technical roles, or a related manufacturing environment; or an AA degree in electronics or technical field.
• Experience troubleshooting or maintaining electronic, RF, radar, avionics, or similar technical systems is highly valued.
• Familiarity with diagnostic instruments such as oscilloscopes, network analyzers, signal analyzers, multimeters, or other electronic measurement equipment.
• Ability to read and…
