May be a combination of the following but not limited to:

• Manufacturing facility
• ISO 5 - ISO 7 Cleanroom
• Laboratory
• Machine shop
• Warehouse
• Office

Requirements

Must have:

• Proficiency in RF/microwave design and simulation software (e.g., HFSS, CST)
• Experience in designing and characterizing vacuum RF power amplifiers (e.g., TWT)
• Solid understanding of amplifier architectures and circuit theory
• Strong analytical skills to analyze circuit performance and troubleshoot issues
• Hands-on experience with RF test equipment (e.g., network analyzers, oscilloscopes)
• Detail-oriented with excellent problem-solving abilities
• Great communication skills and ability to work in a collaborative team environment

• Familiarity with testing protocols for RF amplifiers

Minimum Qualifications

• Bachelor's degree in Electrical Engineering or a related field with at least 6 years of relevant engineering experience in vacuum amplifier device design
• Master's degree in Electrical Engineering or a related field with at least 4 years of relevant engineering experience in vacuum amplifier device design
• Ph.D. degree in Electrical Engineering or a related field with at least 2 years of relevant engineering experience in vacuum amplifier device design
• Basic hands-on tools experience

Benefits

Benefits Include:

• Competitive salary
• Health benefits (medical, dental, vision)
• Vacation time
• A taste of the start-up life
• Exposure to cutting-edge technology in vacuum electronics, materials science, and additive manufacturing.
• Rubbing shoulders and brainstorming with multiple Ph.D. and masters-level engineers

What it’s like to work at Elve

We are a small team (for now!) on a mission to bring the next generation of high-speed wireless connectivity to a billion people worldwide. That kind of impact is not going to be achieved with incremental improvements- we are gunning for orders of magnitude advances in production capability, cost, size, and power in the mm-wave RF amplifier market. We ask “dumb” questions all the time because we always have something to learn. We work really hard, make sure to get good sleep, handle conflict intentionally, and expect great things from each other.
