RESPONSIBILITIES
Develop, maintain, and validate finite element models (FEMs) for spacecraft mechanism and actuation system components and assemblies
Perform structural dynamics analyses including modal analysis, frequency response, random vibration, shock response, and quasi-static load analysis across launch and on-orbit environments
Develop and maintain mechanism-level disturbance models, including jitter and vibration disturbance budgets, and assess impacts on pointing stability and spacecraft performance
Collaborate with the GNC team to characterize and mitigate dynamic disturbances from actuation systems affecting attitude control and pointing accuracy
Define and support dynamic test campaigns including modal surveys, sine sweep, random vibration, and shock testing; correlate FEM predictions with test data
Translate analysis results into clear design recommendations and margin assessments, driving design changes where needed
Support mechanism trade studies, design reviews, and qualification activities with dynamics analysis inputs
Develop and maintain analysis documentation including model descriptions, analysis reports, and test correlation records
Mentor junior engineers and contribute to the continuous improvement of structural dynamics processes and tools
QUALIFICATIONS
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field (Master's preferred)
5+ years of professional experience in structural dynamics analysis for aerospace, defense, or high-reliability applications
Demonstrated proficiency with FEA tools for structural dynamics (NASTRAN, ANSYS, or equivalent)
Experience with modal analysis, random vibration, shock response spectrum (SRS), and frequency response analysis
Familiarity with launch vehicle interface requirements and coupled loads analysis processes
Experience supporting or interpreting dynamic environmental test campaigns and correlating results with FEM predictions
Ability to work cross-functionally with mechanical design, GNC, and systems engineering teams
Excellent written and verbal communication skills
PREFERRED SKILLS AND EXPERIENCE
Experience with spacecraft mechanism or actuation system dynamics, including jitter analysis and disturbance budgeting for precision pointing applications
Familiarity with GNC interface requirements and the impact of structural dynamics on attitude control performance
