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!

  • Cares about clear and descriptive code and naming conventions (especially for command/telemetry)
  • Cares about keeping source code and repositories organized
  • Good at spotting opportunities to generalize and/or autogenerate code
  • Willing to contribute time to necessary evils such as documentation, ground software, continuous integration, and unit testing in addition to fun flight software
  • Willing to engage in design review with others before coding up a storm
  • Can accept constructive criticism in a code review
  • Willing to listen, learn, teach, and ask for help

Additional Requirements:

  • Position may require extended work hours and weekend work.

ITAR Compliance:

  • To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Inversion Space’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past. For more information about this form or the equal employment obligations of federal contractors under Section 503 of the Rehabilitation Act, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at
