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 Mechanisms Team at 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 hardware—actuators latches and thrust vector control (TVC) systems—while 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 a Senior 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 challenges—whether 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:
- Bachelor’s 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
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.
