Inversion was founded in 2021 with the mission to build the first affordable, high cadence return capability for the commercial and defense space industries. With launching to space becoming cheap and frequent, comparable options for return must become available to allow for a robust economy in space. We believe in a future where returning from space is as common as launching to space. Inversion is building reentry vehicles faster and cheaper than ever before through a focus on simplicity.
Embedded Software Engineer
Flight software is the magic that interfaces people and hardware to make a spacecraft come alive. Each step of every mission we fly, from orbit to landing, must be planned and executed by flight software. If it doesn't work or is difficult to operate, then you’ve just built and launched a very expensive brick. Nobody likes a brick, but everyone likes a successful mission! At Inversion, success means bringing the vehicle back down to Earth. As a flight software engineer, you'll work across engineering disciplines to design, develop, and test robust flight software that can function in an extreme environment. Have complete ownership of systems from cradle-to-grave, and help us build a new class of space vehicle set to change how humanity utilizes space!
