Senior Mechanisms Systems Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

TheMechanisms Teamat Relativity Space designs and delivers the complex high-performance mechanical systems that enable launch-vehicle flight landing and reusability. We own the full lifecycle of mission-critical hardwareactuators latches and thrust vector control (TVC) systemswhile partnering deeply with Guidance Navigation & Control (GNC) Avionics and Software to create integrated operable solutions. Our work spans concept development through design analysis test flight operations and recovery always balancing performance reliability and build rate.

About the Role:

As aSenior Mechanisms Systems Engineer you will be the technical and programmatic owner for large cross-discipline mechanism systems such as thrust vector control. Reporting directly to the Mechanisms team you will lead system-level design and integration guiding requirements architecture and verification across hardware and software interfaces.
You will:

• Define system concepts of operations (CONOPS) requirements and verification plans
• Lead integrated product activities across mechanical design actuators GNC avionics and software teams to ensure seamless system performance
• Drive development tests functional verification and flight readiness by authoring test plans executing tests and establishing success criteria
• Anticipate technical and logistical risks develop mitigation strategies and align priorities across engineering disciplines and schedules
• Coordinate the design manufacturing integration and test schedules for complex mechanism systems
• Take hands-on ownership of emergent challengeswhether designing test fixtures specifying sensors writing test automation or leading root-cause investigations

This role occasionally requires travel to test and launch sites and may involve shifted or weekend schedules to support critical milestones

About You:

• Bachelors degree in Mechanical Aerospace or related engineering field and 5 years of relevant experience in design manufacturing assembly or test of complex mechanical or electromechanical systems
• Proven ability to lead multi-disciplinary projects and deliver on ambitious schedules
• Strong technical judgment and the ability to communicate complex concepts across engineering and leadership audiences
• Demonstrated experience balancing requirements cost and schedule while driving system integration and verification

Nice to haves but not required:

• Background in actuator systems flight mechanisms or thrust vector control
• Experience with motor-control tuning and model-based design using MATLAB/Simulink
• Experience with integrated hardware/software testing and verification
• Familiarity with reusability and rapid-iteration development environments
