Structural Engineer III

About the Company

Quantum Space is redefining mobility and autonomy beyond Earth orbit. Our Ranger spacecraft deliver high delta-V and sustained on-orbit maneuverability, enabling missions across cislunar and geostationary space that were previously out of reach.

Responsibilities

• Lead structural analysis and design efforts for spacecraft primary and secondary structures
• Perform detailed analyses including static, modal, vibration, shock, acoustic, and thermal-structural coupling
• Develop finite element models to evaluate structural margins across launch and on-orbit environments
• Build and maintain spacecraft finite element models (FEM) using tools such as NASTRAN, FEMAP, or ANSYS
• Define structural verification strategies and support testing campaigns including vibration and acoustic testing
• Collaborate with mechanical, propulsion, avionics, and thermal teams to ensure structural compatibility
• Provide mentorship and technical guidance to junior structural and mechanical engineers

Requirements

• Bachelor’s or Master’s degree in Aerospace, Mechanical, or Structural Engineering
• 7+ years of experience in structural analysis for spacecraft or launch vehicles
• Strong experience with FEA tools such as NASTRAN, FEMAP, ANSYS, or Abaqus
• Experience building structural models directly from CAD assemblies (Creo, SolidWorks, or NX)
• Expertise analyzing launch and dynamic environments including vibration, shock, and acoustic loads
• Experience supporting structural testing and model correlation using hardware test data
• Knowledge of aerospace structural materials, joints, and lightweight design techniques
• Must be a U.S. citizen, lawful permanent resident, or protected individual per ITAR regulations

Preferred Qualifications

• Experience with composite structures or thin-walled pressure vessels
• Familiarity with Python or MATLAB for analysis automation
• Experience with fracture mechanics tools such as NASGRO
• Familiarity with aerospace structural standards like NASA-STD-5001 or MIL-STD-1540
• Experience in a fast-paced startup environment
