Job Title: Sr Specialist, Structural Engineer Job Code: 33382 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.
