Job Details

RF Hardware Engineer

Tucson, Arizona, United States

Company & Role Overview

Using satellite-based ultra low frequency (ULF) radar, Lunasonde makes the underground world visible, fundamentally transforming our understanding of planet earth. We have built a system that allows us to find the resources our planet needs more efficiently and effectively than anyone else can. We're pioneering subsurface imaging while providing a sustainable approach to resource exploration.

We're looking for an RF hardware engineer that will build the technology that will power our company! You'll be directly working on our novel satellites, building the lowest frequency radars ever created. This role will have a particular focus on the RF hardware and implementations of our radar technology, both for Earth-based testing and space-borne use.

Lunasonde is a small, venture-backed startup, but we'll be growing significantly over the next few months. This role is a great opportunity for someone looking to join an early-stage company on the verge of launching a revolutionary, disruptive technology. We're looking for someone who has prior data science experience, is willing to continuously learn and improve, and wants to make a difference through their work.

Our office is in the scenic Catalina Foothills of Tucson, Arizona. You'll need to be in the office during satellite building and testing, but otherwise you're free to work from wherever you'd like. Our current team is diverse, and we intend to continue building a diverse workforce as an equal opportunity employer.

Role Responsibilities

  • Design low frequency antenna and transceiver systems for both testing and space use

  • Basic CAD skills for prototype designs and working directly with mechanical engineers
  • Extensive antenna impedance matching and electrically small antenna theory
  • Strong hands-on experience with RF systems
  • testing techniques, including using signal analyzers: Real-time Spectrum Analyzers (RSAs) and Vector Network Analyzers (VNAs)

Basic Requirements

  • Bachelor's degree in engineering or scientific discipline OR 5+ years of professional experience
