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
