Senior RF & Plasma Systems Engineer

Applied Angstrom Technology Pte Ltd; Singapore; On-site; SGD 90,000 - 130,000; Full time

Job summary

Applied Angstrom Technology Pte. Ltd. is seeking a Senior RF Engineer to lead RF delivery architecture and plasma source characterization for next‑gen ALE chambers.

You will drive clean-sheet design and dynamic impedance matching to achieve sub-angstrom precision in plasma etching. The role requires deep expertise in high-frequency electronics, plasma physics, and system integration (PLCs, IoT, edge, safety).

Qualifications

• Masters or PhD in science or engineering with emphasis on high frequency electronics or plasma physics.
• Experience with a wide range of plasmas (DC~MW, various pressure and gas conditions).
• Knowledge of unique challenges in large area plasma production and the techniques used in the industry.
• Knowledge in plasma diagnostics (Langmuir probes, optical diagnostic, microwave diagnostic etc.).
• Knowledge in Etch or CVD technology, applications, and film metrology.
• Experience in mechanical design (manufacturability, mechatronics, material properties, vacuum systems, gas flow etc.).
• Experience with system design and module integration on system level (PLCs, IoT, Edge, safety).
• Solid background in RF power delivery, impedance matching, RF sensors, transmission line theory, electronic circuits, amplifiers, sensors etc.

Responsibilities

• Support RF & Plasma tool development/qualification and implementation in Plasma Etch chambers for R&D and Production applications.
• Conduct experiments and characterizations of RF & Plasma systems and components at bench and tool levels using instruments like Network Analyzers, Spectrum Analyzer, Plasma Probes, and DAQ controllers.
• Develop methods to distribute RF through antennas and networks to ignite stable plasmas across frequencies and generators.
• Develop RF & Plasma arc detection and diagnostic methods for R&D and Production.
• Collaborate with Process Engineers and Field/Customer teams to troubleshoot RF & Plasma issues on-site.
