Senior Mechanisms Systems Engineer Verified today

Relativity Space · Long Beach, CA · Space Systems · first seen 2026-09-05

About the Team

The Mechanisms Team designs and delivers complex, high-performance mechanical systems that enable launch-vehicle flight, landing, and reusability. You will own the full lifecycle of mission-critical hardware such as actuators, latches, and thrust vector control systems, partnering with Guidance, Navigation & Control, Avionics, and Software teams. Your work spans concept development through design, analysis, test, flight operations, and recovery.

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. You will report directly to the Mechanisms team and lead system-level design and integration, guiding requirements, architecture, and verification across hardware and software interfaces.

You will:

  • Define system concepts of operations, 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 design, manufacturing, integration, and test schedules for complex mechanism systems
  • Take hands-on ownership of emergent challenges such as 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.

Requirements

  • 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 Have

  • 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 $198,000 USD. Compensation determined by experience, qualifications, and job-related factors. Relativity Space offers competitive salary and equity, generous PTO and sick leave, parental leave, and an annual learning and development stipend.
