The ideal candidate will bring deep technical expertise, creativity, and the ability to work independently on complex engineering challenges.
Key Responsibilities
- Lead complex dynamic analysis of space vehicles and subassemblies.
- Develop and manage the design loads process.
- Build finite element models from geometry and ensure best practices.
- Perform Coupled Loads Analysis (CLA) model preparation and result assessment.
- Provide recommendations on model size and runtime limits, including trade-offs.
- Support design teams with timely analysis and technical insights.
- Assist in environmental criteria development and support shock, acoustics, and vibration testing.
Qualifications
Education:
Bachelor’s degree in mechanical engineering or a related technical field.
Experience:
Minimum of 5 years hands-on experience in mechanical/structural dynamics analysis of spacecraft.
Preferred Qualifications
- Advanced degree in Mechanical Engineering or related field with an emphasis in dynamics.
- Familiarity with Statistical Energy Analysis (SEA) methods for predicting high-frequency dynamic environments.
Soft Skills
- Strong interpersonal skills and ability to collaborate within multidisciplinary teams.
- Excellent written and verbal communication skills.
- Meticulous attention to detail for accuracy in documentation and deliverables.
- Flexibility and adaptability in a fast-paced environment.
- Proven ability to work independently on complex problems.
Technology Stack

- Advanced coding in supporting programs (FEMAP API, MATLAB, Python).
- Strong proficiency in MS Excel (including macros) and MS Office tools.
- Ability to run NASTRAN outside of pre/post systems.
Physical Requirements
- Ability to work in a standard office environment and use a computer for extended periods.
- Remote work capability with approximately 20% travel (domestic and international).
Additional Requirements
Must be a U.S. person (compliant with ITAR regulations).
