About The Position

Quaise Energy is seeking a highly motivated early-career RF Engineer to support the design, modeling, testing, and deployment of high-power RF and millimeter-wave transmission systems for their millimeter-wave drilling technology, and further the development of high power, high efficiency gyrotron sources. This role will collaborate with other cross-functional teams to apply advanced electromagnetic theory and RF design skills in a fast-moving, multidisciplinary R&D environment, as well as troubleshoot and resolve RF-related issues.

Requirements

• Bachelor’s degree in Electrical Engineering, RF Engineering, Applied Physics, or related field is required.
• 0–3 years of relevant research or industry experience in RF, microwave, or millimeter-wave engineering.
• Strong foundation in electromagnetic theory and RF engineering principles
• Familiarity with millimeter-wave transmission systems and high-power RF components such as RF windows (e.g., diamond windows), mode converters, tapers, or high-power loads
• Understanding of wave propagation, waveguide modes, impedance matching, and microwave measurement techniques
• Familiarity with RF test equipment such as vector network analyzers (VNAs), spectrum analyzers, and power measurement systems
• Exposure to vacuum electronic devices (e.g., gyrotrons, klystrons, TWTs) or high-voltage RF environments
• Experience using electromagnetic or multiphysics simulation tools (HFSS, CST, COMSOL, MATLAB, or similar)
• Programming experience (MATLAB, Python, or similar) for data analysis, modeling, or automation
• Awareness of thermal, mechanical, and materials considerations in high-power RF systems
• Experience supporting experimental system integration, troubleshooting, or lab-to-field technology transitions
• Strong analytical and problem-solving skills with willingness to learn through hands-on experimentation
• Ability to collaborate effectively in a multidisciplinary startup environment
• Excellent written and verbal communication skills
• Strong organizational skills and attention to detail
• Proficient with Microsoft Office Suite or related software.

Nice To Haves

• PhD in Electrical Engineering, Applied Physics, RF/Microwave Engineering, or related discipline preferred.
• Experience with high-power RF systems, vacuum electronics, or gyrotron technology is a strong plus.

Responsibilities

• Support the design, simulation, and testing of RF and millimeter-wave components and transmission systems.
• Assist in development and integration of waveguide components such as bends, tapers, mode converters, and diagnostics.
• Perform electromagnetic modeling and simulation using tools such as HFSS, CST, COMSOL, MATLAB, or similar.
• Participate in laboratory experiments, hardware integration, and field testing activities.
• Analyze test data and contribute to iterative design improvements.
• Prepare technical documentation, test reports, and design notes.
• Collaborate with mechanical, electrical, and field engineering teams to support system development.
• Assist in packaging and ruggedization of RF systems for transition from laboratory to field deployment.
• Support troubleshooting of RF performance issues and system diagnostics.
• Contribute to safe lab practices and continuous improvement of engineering processes.
• Perform other related duties as assigned.
