5+ years expEngtal is seeking a Senior Structural Dynamics Engineer to lead the prediction, management, and verification of Line-of-Sight (LoS) stability for next-generation satellite platforms. This role involves architecting workflows that define GNC algorithms' interactions with flexible spacecraft hardware and ensuring high-performance satellites remain stable during precision maneuvers.

Responsibilities
Micro-Vibration Analysis: Lead frequency-domain and time-domain jitter analyses, predicting LoS errors caused by internal disturbances (RWAs, cryocoolers) and thermally induced structural transients (e.g., snap, stick-slip)
GNC Flex Model Generation: Generate and validate reduced-order models (e.g., Craig–Bampton superelements) for GNC teams, ensuring accurate capture of high-frequency flexible modes and residual stiffness
Control–Structure Interaction (CSI): Analyze spacecraft control stability in the presence of flexible modes; advise on filter design and notch placement to prevent resonance during slews
Methodology Development: Architect automated workflows for sine vibration predictions and Coupled Loads Analysis (CLA) to rapidly assess design iterations
Test Correlation: Design and support modal survey testing, applying correlation techniques to statistically validate analytical models against physical hardware
Qualification
Required
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field
5+ years of experience in structural dynamics, loads analysis, or vibroacoustics for spaceflight systems
Deep expertise in Simcenter Nastran or advanced proficiency with Nastran SOL 111/112 with the ability to transition quickly
Strong foundation in signal processing (FFT, PSD, windowing techniques)
Solid understanding of model reduction physics (modal effective mass, residual vectors)
Demonstrated ability to use Python, MATLAB, or DMAP to process large engineering datasets (e.g., .op2 files) and manage complex CLA inputs
Preferred
Master's or PhD in Engineering with a focus on Structural Dynamics or Controls
Experience defining predictive damping schedules and correlating Q-factors from modal surveys or tap tests
Hands-on experience stabilizing high-bandwidth control loops on flexible spacecraft, including notch filters and input shaping
Experience developing custom solver logic or simulation kernels (C/C++) for novel physics problems (e.g., slosh, complex damping)
Prior ownership of a critical subsystem test campaign (e.g., micro-vibration characterization or modal survey)
Benefits
Comprehensive medical, dental, and vision coverage
401(k)
Flexible vacation policy and paid holidays
Family leave, pregnancy leave, and military service leave
Inclusive, equal-opportunity workplace with reasonable accommodations available
