About the Team

The Mechanisms Team designs and delivers the complex, high-performance mechanical systems that enable launch-vehicle flight, landing, and reusability. You will own the full lifecycle of mission-critical hardware including actuators, latches, and thrust vector control (TVC) systems, partnering deeply with Guidance, Navigation & Control (GNC), Avionics, and Software to create integrated, operable solutions.

About the Role

As 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 including designing test fixtures, specifying sensors, writing test automation, and 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
  • 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 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

  • 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

Compensation

Hiring range: $132,000 to $181,500 USD. Compensation determined based on experience, qualifications, and job-related factors. Benefits include competitive salary and equity, generous PTO and sick leave, parental leave, and annual learning and development stipend.
