Spacecraft/Radar Engineer



Tucson, AZ, USA
Posted on Friday, June 30, 2023

Company & Role Overview
Using satellite-based ultra low frequency 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 a Spacecraft/Radar Engineer to help build the satellites that will power our company! You’ll be directly working on our novel satellites, building spaceworthy hardware and software that will collect the first ever images of the deep subsurface. This role will have a particular focus on command, control, and data handling (CC&DH), telemetry tracking and command (TT&C), and electrical power subsystems (EPS).

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 spacecraft engineering experience, is willing to continuously learn and improve, and wants to make a difference through their work.

Our office is in the 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.
