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
