Job description

Position Responsibilities

• Leads or supports structural, dynamic, and thermal analysis for composite structures and electronics enclosures
• Leads the design and development of composite components from concept through production, including layup schedules, tooling design, and manufacturing process definition
• Develops composite structural designs using fiber‑reinforced polymers (CFRP, GFRP) and hybrid material systems
• Performs stress and fatigue analysis specific to composite materials and bonded joints
• Develops mechanical drawings and specifies dimensional tolerances with an emphasis on composite fabrication and assembly
• Develops assembly instructions, layup procedures, cure cycle documentation, and test procedures
• Develops test plans and test procedures to verify structural designs against environmental and load requirements
• Works on complex issues where analysis of situations or data requires in-depth knowledge of composite behavior and failure mechanisms
• Executes team assignments effectively following the given schedule, milestone, and available resources. May coordinate activities of other engineering and manufacturing personnel (Team Lead)
• Other duties as assigned

Basic Qualifications (Required Skills & Experience)

• Minimum 8 – 12 years of relevant technical experience in Mechanical Engineering, of which a minimum of 5 years focused on composite structure design and production for aerospace applications
