About this role

Apex is hiring a Spacecraft Mechanisms Build Engineer to develop, integrate, and scale electromechanical hardware for commercial satellite buses, with focus on rotating assemblies, actuators, and motor-driven mechanisms. You'll support build, test, and qualification of flight-grade components while collaborating across mechanisms, avionics, controls, manufacturing, and test teams to enable production scalability.

What you'll do

  • Build, integrate, and qualify spacecraft electromechanical hardware and long-life rotating assemblies
  • Develop and execute component and system-level test campaigns for motor-driven spacecraft mechanisms
  • Design test setups, fixtures, and instrumentation for validating actuators and rotating hardware
  • Support manufacturing scaling of precision electromechanical components and actuator systems
  • Integrate and validate motor drive systems, sensors, and mechanism telemetry with controls and avionics teams
  • Execute environmental testing (vibration, thermal vacuum, shock, lifetime) and drive root cause investigations

What they're looking for

  • Electromechanical systems design and troubleshooting
  • Electric motor and actuator hardware expertise
  • Sensor integration (Hall effect, rotary encoders, resolvers, microswitches)
  • Hardware bring-up, integration, and test execution
  • Manufacturing process development and quality documentation
  • Vibration and thermal vacuum testing
  • Mechanical and electrical problem-solving
  • Flight or high-reliability hardware experience
