Principal Structural Dynamics Engineer, Space Based Interceptors

YOUR MISSION

Lead the analysis and validation of spacecraft and/or Space Based Interceptors to ensure survivability and performance under dynamic environments, including launch, on-orbit, and mission operations.

RESPONSIBILITIES

• Perform detailed structural dynamics analyses, including modal, harmonic, random vibration, shock, and transient response simulations.
• Develop documentation and best practices across engineering team including modeling tools, process documentation, and analysis templates.
• Develop and validate finite element models (FEMs) of spacecraft and/or missile structures and subsystems, ensuring accuracy in predicting dynamic behavior.
• Define and lead dynamic testing campaigns, including vibration, shock, and acoustic testing, to verify structural integrity and correlate models with test results.
• Collaborate with cross-functional teams, including mechanical, thermal, and systems engineering, to ensure dynamic requirements are integrated into the design process.
• Provide expertise in structural dynamics during trade studies, design reviews, and critical decision-making processes.

QUALIFICATIONS

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 12+ years of experience in structural dynamics analysis for aerospace, defense, or high-reliability applications.
• Proficiency in finite element analysis (FEA) tools such as FEMAP/NASTRAN or HyperWorks/OptiStruct.
• Experience in spacecraft and/or missile defense dynamic environments, including launch loads, aero loads, vibration, and shock.
• Strong understanding of structural mechanics, fracture mechanics, material properties, and failure modes in aerospace applications.
• Hands-on experience with environmental testing, including random, sine, and sine burst vibration.

PREFERRED SKILLS AND EXPERIENCE

• Master’s degree in Mechanical Engineering.
• 15+ years of experience in structural dynamics analysis for aerospace, defense, or high-reliability applications.
• Thermal and fluid systems analysis experience
• Mastery of spacecraft-specific structural dynamics challenges, such as coupled loads analysis and dynamic coupling between subsystems.
• Mastery of missile defense-specific structural dynamics challenges, such as aerothermal loading.
• Experience working with lightweight structures, composites, and advanced materials.
• Proficiency in CAD tools, such as SolidWorks and NX for integrating FEMs with detailed vehicle assembly models – Teamcenter for PLM
• Hands-on experience with instrumentation for dynamic testing, including accelerometers, strain gauges, and data acquisition systems.
• Hands-on experience with environmental testing including shock and acoustic tests.
• Demonstrated experience with full program life cycle (capture to launch)

COMPENSATION

Base Salary: $185,000-$315,000
Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave

ADDITIONAL REQUIREMENTS

• Ability to maintain or obtain TS/SCI clearance.
• Work Location: while we observe a hybrid work environment, you will need to be onsite as the business needs require. On an average week, you can expect to spend at least 3 days per week in office at our Gravity Works facilities.
• Physical demands may include frequent standing, sitting, walking, bending, and lifting or carrying items up to 20lbs.
