Senior Mechanisms Systems Engineer

Requirements

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

• 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
• 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
• 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
