Principal Mechanical Engineer

Lead Complex Engineering Projects That Make a Difference

Are you an experienced Mechanical Design Engineer looking to take the lead on technically challenging projects within the Aerospace & Defence sector?

Elevation Recruitment Group are looking for a Principal Mechanical Design Engineer to provide technical leadership across complex engineering programmes, leading a team of talented engineers while driving innovation, quality and continuous improvement. This is an excellent opportunity to influence major design projects from concept through to customer approval, working on highly engineered mechanical systems in a collaborative, multi-disciplinary environment.

If you enjoy solving complex engineering challenges, mentoring others and delivering first-class technical solutions, we'd love to hear from you.

As Principal Mechanical Design Engineer, you'll take ownership of major design programmes, providing both technical direction and people leadership. You'll oversee the delivery of innovative mechanical solutions while ensuring projects meet customer expectations for quality, cost and timescales.

Working closely with internal teams and customers, you'll champion engineering excellence, support continuous improvement initiatives and play a key role in developing the next generation of engineers.

• Lead and manage a team of Mechanical Design Engineers, supporting their technical development and day-to-day workload.
• Deliver complex mechanical design projects from concept through to customer approval.
• Provide technical leadership across multi-disciplinary engineering teams.
• Drive continuous improvement initiatives, particularly around non-conformance reduction and root cause analysis.
• Produce and review mechanical specifications, calculations, drawings and technical documentation.
• Ensure designs meet relevant engineering standards, customer requirements and quality expectations.
• Lead design reviews both internally and with customers.
• Coordinate mechanical activities alongside Process, Transmission Systems and Marine Engineering disciplines.
• Develop engineering best practice, processes and technical standards across the business.
• Mentor and coach junior engineers to support long-term capability development.

We're looking for a technically strong engineering leader with experience delivering complex mechanical design solutions within a highly regulated engineering environment.

You'll ideally have experience in:

• Transmission systems, gearboxes, gears and heavy mechanical equipment.
• Aerospace, Defence, Marine or other complex engineering sectors.
• Mechanical calculations, specifications, drawings and design documentation.
• Root cause analysis and design improvement methodologies.
• Leading technical teams and managing multiple engineering projects.
• Customer-facing design reviews and technical presentations.
• CAD software such as Siemens NX, Solid Edge and AutoCAD.

• Degree qualified (Bachelor's or Master's) in Mechanical Engineering or a related discipline.
• Chartered Engineer status (or working towards) would be advantageous.
• Experience within Aerospace & Defence or another highly regulated engineering environment.
• Strong understanding of quality management systems such as AS9100 and ISO 9001.

Due to the nature of the work, applicants must be Sole UK Nationals and able to satisfy relevant security clearance requirements.

This is an opportunity to join a highly skilled engineering team working on technically challenging, high-profile programmes where you'll have genuine influence over engineering decisions and project delivery.

You'll benefit from:

• Working on complex, innovative engineering projects.
• Leading and developing a talented engineering team.
• A collaborative environment that encourages continuous improvement and innovation.
• Excellent opportunities for career progression and professional development.
• Competitive salary and benefits package.

If you're an experienced Mechanical Design Engineer ready to step into a senior technical leadership role, we'd love to hear from you.
