Job Title : Specialist, Structural Engineer

Job Code : 29030

Job Location : Huntsville, AL

Job Schedule : 9 / 80 : Employees work 9 out of every 14 days – totaling 80 hours worked – and have every other Friday off

Job Description :

In this role, you will perform structural analysis to verify product designs meet structural performance requirements and assist with preliminary design verification. This role requires an experienced structural engineer with a strong technical foundation in aerospace structures, particularly rocket propulsion, a proactive mindset, and a passion for solving problems that can be but are not typically complex in high-performance environments.

As a key contributor, you will manage and / or support structural modeling and analysis efforts for solid rocket motor (SRM) components throughout the product lifecycle—from early development through qualification and production. You will collaborate closely with cross-disciplinary teams, interface with customers, and drive technical excellence. Work will be performed under general oversight.

Why This Role Matters

You won't be just running models - you'll be influencing major design decisions and contributing directly to flight-critical hardware. This position is a unique opportunity to work on cutting-edge propulsion technologies that drive national defense initiatives.

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.

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.

Collaborate with thermal, CFD, and performance teams to establish pressure, thermal gradient, and mechanical loading conditions. In some cases, derive boundary conditions and load cases based on mission and design requirements.

Apply classical methods to validate and supplement numerical results, especially for preliminary design trades or quick-turn assessments.

Import and simplify solid CAD models from design teams to develop robust, clean geometry suitable for analysis.

Determine margins of safety against yield, ultimate failure, buckling, HCF, LCF, and fracture using established industry standard practices and internal allowables.

Produce high-quality technical reports, stress notes, and presentations that clearly outline methods, assumptions, and conclusions for both internal reviews and external customer delivery.

Participate in formal and informal design reviews. Communicate results, trade-offs, and risk areas effectively to multidisciplinary audiences, including program management and external customers.

Contribute to internal tool development, analysis automation, and knowledge capture to enhance team efficiency and standardization.
