Flight Sciences Multi-Body Dynamics Engineer; Level 4

Basic Qualifications

• Bachelor's degree in Aerospace, Structural, or Mechanical Engineering or similar technical field
• 8 years of professional work experience performing rigid body kinematics and/or dynamics simulation
• 3 years of experience performing multi-body dynamics using MSC ADAMS or equivalent
• Experience leading kinematics/dynamics analyses while collaborating effectively with adjacent disciplines in a highly integrated team environment
• Experience building and correlating multi-body dynamics models with test data for model validation
• Proficiency in programming and scripting using Matlab, Python, or equivalent
• Ability to obtain and maintain a Secret security clearance, thus US citizenship is required.

• Lead structural dynamics analyses that shape the performance and survivability of missile and spacecraft flight hardware, from early concept through flight.
• Develop, refine, and own high-fidelity dynamic models using both in-house and industry-standard tools to simulate mechanical loads, deployment mechanisms, and complex separation events.
• Drive loads development at both the component and system level, translating real-world environments into actionable design criteria and validated engineering solutions.
• Plan and execute dynamic and static test campaigns—including separation events—then synthesize results into clear, data-driven insights that influence design decisions.
• Partner across a multidisciplinary engineering team to perform design trades, guide architecture decisions, and ensure structural integrity throughout the product lifecycle.
• Define and support dynamic test requirements, oversee test execution, and lead data reduction and correlation efforts to ensure alignment between analysis and test.
• Communicate complex technical findings with clarity and confidence, delivering high-quality documentation and presenting to internal teams, customers, and program leadership at key design reviews and technical forums.

• This position is full-time onsite at our Huntsville, AL, Sunnyvale, CA or Littleton, CO campuses
• The ability to obtain and maintain a Secret security clearance, thus US citizenship is required.

• Master’s degree or PhD in Aerospace, Structural, or Mechanical Engineering with 10 years of rigid body kinematics and/or dynamics simulation experience
• Experience mentoring and training junior engineers in multi-body dynamics simulation techniques and best practices
• Proficiency performing kinematic/dynamic analysis of mechanisms, test support equipment, and stage separation
• Proficiency building and correlating multi-body dynamics models with test data for model validation
• Experience using NX/Nastran, Abaqus, ADAMS, LS-Dyna, Matlab, Mathcad and CREO for analysis of spacecraft, aircraft, or missiles
• Experience in the planning and execution of static, vibration, acoustic, modal, and shock testing for aerospace flight hardware
• Excellent communication skills—both written and verbal, self-motivated, and able and willing to support multiple projects.
