Job Description

Are you a Structural Dynamics Engineer, passionate about solving spacecraft jitter, micro-vibration, and control-structure interaction challenges at the system level? On offer is the opportunity to join a high-growth space company developing next-generation satellite platforms requiring extreme pointing stability. You’ll take technical ownership of line-of-sight stability, micro-vibration prediction, reduced-order modeling, and the interaction between flexible structures and advanced GNC algorithms. You will be joining a team driving the future of precision spacecraft performance. You’ll build digital testbeds, architect structural-control workflows, and work across structural engineering and systems analysis to ensure high-fidelity behavior during demanding mission operations. This position would suit a high-end structural dynamics specialist who thrives at the intersection of FEM, GNC, signal processing, and simulation automation.

Job Responsibility

  • Lead micro-vibration and jitter analysis, predicting LoS stability impacts from reaction wheels, cryocoolers, mechanisms, and thermal transients
  • Generate and validate reduced-order flex models (e.g., Craig-Bampton superelements) for GNC time-domain simulations
  • Analyze control-structure interaction (CSI) and advise on notch filters, controller shaping, and stability margins for precision slews
  • Architect automated workflows for Coupled Loads Analysis (CLA) and sine vibration predictions to accelerate design iterations
  • Plan, support, and correlate modal survey tests, validating FEM fidelity and structural mass/stiffness properties
  • Drive methodology improvements in model reduction, damping interpretation, and dataset handling
  • Collaborate with GNC, pointing, thermal, structural, and systems teams to align performance budgets and simulation models
  • Document analytical methods, model assumptions, and verification results

Requirements

  • Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or similar field
  • 5+ years’ experience in structural dynamics, loads, and vibroacoustics for spacecraft
  • Deep expertise in Nastran or Simcenter Nastran
  • Strong understanding of signal processing and model reduction
  • Proficiency in Python, MATLAB, or DMAP for automating analysis and processing large datasets
  • Eligible for or willing and able to obtain a U.S. DoD Top Secret Security Clearance
