• Ownership of critical structures such as mass-efficient transportable shielding systems, container system, and high temperature graphite and metallic systems
• Conduct trade studies and develop designs to meet program requirements
• Perform detailed thermomechanical analysis (static strength, durability/fatigue) and dynamic analysis (vibration, shock) to determine structural integrity (margins of safety) using both hand calculations and finite element tools
• Develop and execute manufacturing/assembly instructions and test plans
• Create and manage a Bill-Of-Materials (BOM)
• Find and develop suppliers for components
• Own subassembly design, manufacturing, and test schedules
• Own risk analysis (FMEA) for subsystems
• Collect requirements, provide expertise and feedback to engineers in other functional areas via clear, constructive communication

Benefits

• Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans
