Security Clearance: Must currently hold or be eligible for SC Clearance

We are looking for an experienced Mechanical Design Engineer to join an engineering team in Derby on an initial 12-month contract.

This is a hands-on engineering design role rather than a CAD drawing position. You will be responsible for developing engineering solutions, progressing modifications through the full design and review process, and ensuring designs meet defined system and technical requirements.

Due to the secure nature of the work, the position is office based in Derby. Candidates must either currently hold SC Clearance or be eligible to obtain it.

Key Responsibilities:

• Mechanical design and development using Siemens NX
• 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

This is a 12-month contract offering £40–£44 per hour, Outside IR35.

The role is office based in Derby due to the nature of the project, with the option to condense your working hours into a 4-day week if preferred
