Original job description

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

The Interplanetary Sciences Program was established to expand access to scientific exploration across our solar system. Its mission is to make planetary research faster, more affordable, and more capable than ever before by rethinking how science missions are designed, built, and operated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs. By creating a sustainable model for interplanetary exploration, we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge, broadens participation, and inspires the next generation of explorers.

About the Role:

Relativity Space’s Interplanetary Sciences Program is developing a privately funded science mission to Mars targeted for 2028. This mission will map shallow subsurface ice and geology, characterize Martian weather, enable next generation onboard processing and communication, and demonstrate a new philanthropic public-private partnership model for space science.

We’re hiring one Staff Assembly, Integration & Test (AI&T) Engineer to own the integration and test campaigns for the Mars orbiter. You’ll define how the spacecraft and its payloads are assembled, verified, and prepared for launch, then lead that work hands-on with the engineering team. This is a full-time position based at Relativity Space HQ in Long Beach, California.

What you’ll do:

Own the spacecraft integration flow and test campaigns, from component and subsystem testing through vehicle-level environmental testing and launch preparation.
Develop assembly and integration procedures, test plans, acceptance criteria, and verification approaches with systems and discipline leads.
Plan and lead any system level thermal, vibration, EMI/EMC, functional, and end-to-end integrated spacecraft payload tests.
Design the mechanical and electrical ground support equipment, tooling, and test setups needed for the campaign.
Identify and establish the required infrastructure for the integration campaign, from test assets to cleanrooms.
Lead test readiness reviews, execute tests, assess results, resolve discrepancies, and drive failures to root cause and closure.
Shape the spacecraft design while it is still evolving by identifying assembly, access, handling, and testability risks early.
Maintain clear hardware configuration, assembly and test records, and verification evidence through delivery and launch.

About You:

Bachelor’s degree in aerospace, mechanical, electrical, or a related engineering field
7+ years of hands-on experience integrating and testing spacecraft or similarly complex flight hardware
Experience leading spacecraft or payload integration and environmental test campaigns, including thermal vacuum and vibration testing
Ability to write and execute test plans and procedures, assess test data, and close verification requirements
Strong hardware troubleshooting skills and the judgment to make sound technical decisions under schedule pressure
Experience working across hardware, software, and systems engineering teams to take a flight system from development through delivery

Nice to haves, but not required:

Spacecraft-level AI&T ownership on a deep-space or other one-of-a-kind mission
Optical communications, precision pointing, or other tightly coupled payload integration
Electrical ground support equipment, automated test systems, and hardware-in-the-loop testing
Cleanroom operations, ESD controls, and flight hardware handling
Launch site integration or launch campaign support

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.

Hiring Range:

$164,000 - $246,000 USD

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

If you need a reasonable accommodation, please contact us at accommodations@relativityspace.com.

Please note: Relativity Space does not accept unsolicited resumes, candidate profiles, or referrals from recruitment agencies or search firms. Any unsolicited submission - via email, our website, social media, or directly to an employee - will be deemed the property of Relativity Space, and no fee will be owed absent a current, fully executed agreement with Talent Acquisition that specifically authorizes submissions for the applicable role.
