Applications Engineer - RF Power

About the role

To complement our team, we are looking for a customer- and team-oriented individual for our division Plasma Control Technologies at the San Jose site as an Applications Engineer - RF Power. For over 75 years, Comet has followed its curiosity, becoming a leading Swiss technology company worldwide. We develop and produce innovative high-tech components and systems based on X-ray and radio-frequency technology, contributing to safer, more efficient, and more sustainable production, mobility, and communication. In the Plasma Control Technologies division, we manufacture specialized components required for precise control of plasma processes used in the production of memory chips or touch screens for sensors, smartphones, or tablets.

Summary: Provide advanced RF engineering support for integration, optimization, and troubleshooting of RF Matching Networks, RF Generators, and related RF subsystems. Utilize hands-on fabrication, machining, and mechanical engineering capabilities to support fixturing, prototype development, and practical problem‑solving during customer tool integration.

Responsibilities

• Integrate RF subsystems into semiconductor manufacturing equipment and verify performance.
• Perform RF characterization, impedance matching, and power delivery optimization.
• Design, modify, or fabricate fixtures, brackets, mechanical interfaces, and test assemblies to support lab evaluation or customer integration (including the operation of machine shop tools such as mill, lathe, drill press, band saw) for quick‑turn prototyping.
• Build, assemble, or modify mechanical components required for RF experiments or tool fit checks.
• Conduct lab testing, data analysis, and troubleshooting, including root‑cause investigation combining RF and mechanical considerations.
• Support pre‑sales and post‑sales efforts with technical presentations, demonstrations, and customer training.
• Provide actionable customer feedback to R&D for both RF and mechanical interface improvements.
• Generate documentation, application notes, build instructions, and technical illustrations.
• Provide on‑site and remote customer support, including hands‑on adjustments and mechanical modifications.
