How to Become a Structures & Mechanisms Engineer
Build hardware that survives launch and still opens on command in orbit.
Role Overview
Structures & mechanisms engineers design the physical skeleton of a spacecraft and the moving parts that must deploy flawlessly after months in storage. The role bridges analytical and handsโon work: you run FEA Monday and inspect a test article on the shaker Wednesday.
Key Responsibilities
- Perform finite element analysis (FEA) in Nastran, Abaqus, or ANSYS.
- Design composite layup for CFRP, GFRP, and titanium fittings.
- Lead vibration, acoustic, shock test campaigns on a shaker table.
- Develop kinematic designs for hinges, latches, solar array drives, antenna gimbals, payload doors, and separation systems.
- Conduct launch load analysis using coupled loads analysis (CLA) methodology per NASAโSTDโ5002.
- Perform mechanism kinematic and force analysis with CATIA DMU Kinematics or Adams Multibody.
- Correlate vibration test data with FEA models and adjust models to meet specifications.
- Prepare stress analysis reports and lead test readiness reviews.
Qualifications
- Bachelorโs degree in Aerospace, Mechanical, or Civil Engineering (or related).
- Proficiency with FEA tools and composite material design.
- Experience with launch load environments and launch vehicle testing.
- Strong engineering judgement and ability to translate physical load paths without excessive reliance on software.
- Handsโon experience with torque wrenches, strain gauges, and test equipment.
Desired Experience
- Graduate study or professional experience in structural dynamics, aeroelasticity, or aerospace structures.
- Leadership of subsystem ownership in structures or mechanisms projects.
- Previous involvement in vibration and acoustic preโtest prediction reviews.
Benefits & Compensation
- USโcentric salary ranges: Entry level $88Kโ$135K, Senior level $200K.
- Opportunities in commercial and agency/civilian roles worldwide.
Career Progression
Typical career path spans 5โ8 years from Junior Through Principal Structures Engineer, including opportunities to lead up to 20 engineers.
Reality Check
- Good fit if you enjoy translating load paths mentally before using FEA software, moving between CAD screens and test floors, selecting materials, and conducting handsโon hardware work.
- Bad fit if you prefer purely software work, dislike handsโon hardware, or seek rapid lateral moves.
