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
