About the role
Senior Mechanisms Engineer responsible for owning a critical vehicle mechanism subsystem from concept through flight, with potential focus areas including separation systems, landing gear, aero control surfaces, or electromechanical actuation. Hands-on role interfacing with propulsion, structures, avionics, GNC, and launch operations.
Responsibilities
- Own your mechanism subsystem from concept through design, analysis, test, and flight.
- Drive structural and kinematic design for minimum mass while meeting strength, stiffness, fatigue, and operational-life requirements across ascent, entry, landing, and reuse environments.
- Balance performance, manufacturability, cost, and schedule in every design decision
- Perform analysis — hand calculations, FEA, tolerance stack-ups — and validate predictions with test and flight data.
- Define and execute qualification and acceptance test campaigns; author procedures, acceptance criteria, and anomaly dispositions.
- Develop and maintain engineering drawings, models, and release documentation.
- Work directly on the factory floor with manufacturing to iterate quickly and resolve build issues in real time.
- Troubleshoot hardware anomalies, perform root cause analysis, and implement design improvements.
- Support launch operations, post-flight inspection, and refurbishment planning.
Qualifications
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field.
- 5+ years of experience designing mechanisms or mechanical systems for flight vehicles or high-performance hardware.
- Experience taking hardware from concept through build, integration, and test.
- Strong fundamentals in structural mechanics, kinematics, materials, and manufacturing processes.
- Proficiency with CAD (NX, SolidWorks, CATIA, or Creo) and creating engineering drawings to ASME Y14.5 GD&T standards.
- Proficiency with FEA tools (ANSYS, Nastran, or Abaqus) for mechanism load-path and dynamic problems.
- Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
