• Develop engineering solutions from initial requirements through to final design
• Take modifications through the full design review and approval process
• Interpret and work from system and technical requirements
• Produce and develop robust engineering designs
• Carry out design calculations and engineering assessments where required
• Work closely with systems, manufacturing and wider engineering teams
• Support technical and design reviews
• Ensure designs comply with relevant engineering standards and project requirements
• Manage design changes and modifications throughout the engineering lifecycle
• Provide technical justification for design decisions

Requirements:

• Strong Mechanical Design Engineering background
• Proven experience using Siemens NX
• Experience working on complex engineered products or systems
• Strong understanding of engineering design principles
• Experience taking designs/modifications through formal design reviews
• Comfortable working from system and technical requirements
• Able to provide engineering input beyond simply producing drawings
• Previous Rolls-Royce experience would be a strong advantage
• Currently hold or be eligible to obtain SC Clearance
