Job Description:

Join our team shaping the next generation of solid rocket propulsion systems. We are seeking aSr. Specialist Structural Engineer (Structures and Dynamic) for our Sacremento CA or Huntsville AL this role you will perform structural analysis to verify product designs meet structural performance requirements and assist with preliminary design verification. We are seeking an experienced structural analyst with a strong technical foundation in aerospace structures particularly rocket propulsion a proactive mindset and a passion for solving complex problems in high-performance environments.

As a key contributor you will lead and support structural modeling and analysis efforts for solid rocket motor (SRM) components throughout the product lifecyclefrom early development through qualification and production. You will collaborate closely with cross-disciplinary teams interface with customers and drive technical excellence.

Essential Functions:

• Structural Analysis Ownership: Drive analysis tasks for SRM components including metallic and composite motor cases nozzles insulation and propellant grains. Ensure structural integrity across all phases of flight and ground handling.
• FEA Modeling & Execution: Build and execute finite element models using ANSYS ABAQUS or comparable tools. Model components using isotropic orthotropic and viscoelastic material definitions with nonlinear and temperature-dependent properties.
• Load Development: Collaborate with thermal CFD and performance teams to establish pressure thermal gradient and mechanical loading some cases derive boundary conditions and load cases based on mission and design requirements.
• Closed-Form Support: Apply classical methods to validate and supplement numerical results especially for preliminary design trades or quick-turn assessments.
• CAD & Geometry Integration: Import and simplify solid CAD models from design teams to develop robust clean geometry suitable for analysis.
• Margin of Safety Evaluation: Determine margins of safety against yield ultimate failure buckling HCF LCF and fracture using established industry standard practices and internal allowables.
• Documentation & Reporting: Produce high-quality technical reports stress notes and presentations that clearly outline methods assumptions and conclusions for both internal reviews and external customer delivery.
• Design Integration: Participate in formal and informal design reviews. Communicate results trade-offs and risk areas effectively to multidisciplinary audiences including program management and external customers.
• Process Improvement: Contribute to internal tool development analysis automation and knowledge capture to enhance team efficiency and standardization
• Ability to obtain a US Security Clearance.

Qualifications:

• Bachelors Degree and minimum 6 years of prior Structural Enginering engineering experience.Graduate Degree and a minimum of 4 years of prior Structural Enginering engineering experience.In lieu of a degree minimum of 10 years of prior Structural Enginering engineering experience.

Preferred Additional Skills:

• Masters degree strongly preferred
• Proven experience in linear nonlinear and dynamic structural analysis supporting design and qualification of solid rocket motors.
• Proficiency with FEA tools such as ANSYS Mechanical; experience with ANSYS MAPDL or Python scripting is highly desirable.
• Familiarity with structural assessment and design of filament-wound composite pressure vessels is a strong asset.
• Demonstrated ability to interpret aerospace structural requirements and coordinate load development with cross-functional teams.
• Working knowledge of structural instabilities material nonlinearities and coupled load environments.
• Exposure to full lifecycle aerospace SRM propulsion product development from design through manufacturing and test.
• Strong technical communication skills and proficiency with Microsoft Office (Word Excel PowerPoint).
• Ability to work under general oversight.
