Senior Mechanical Engineers
Mechanical Engineer – Defence & Engineering Projects
About the Role
We are recruiting and developing career-minded professionals to strengthen our multi-discipline engineering delivery capability within the UK’s defence industry. Our projects span nuclear submarine fleet solutions, air, land, and sea defence systems, and manufacturing facility development—all within complex and evolving environments.
As part of a >/ 300-strong team across the UK, you’ll provide mechanical engineering support to key client projects within a growing team based in Glasgow, Bristol, or Reading.
This is an exciting opportunity for an engineer who seeks exposure to a diverse range of engineering disciplines and project phases. With projects expanding nationally, you’ll have the chance to shape your career path while contributing to high-impact challenges.
Experience in defence-related engineering is helpful, but we also welcome mechanical design professionals eager to transition into a technically demanding sector.
Key Responsibilities
- Provide mechanical engineering support during the development and analysis of mechanical systems and equipment.
- Produce comprehensive technical documentation, including:
- Diagrams
- Technical specifications
- Supporting calculations and analysis
- Design evidence and justifications
- Demonstrate leadership and problem-solving to influence key design decisions.
- Deliver a professional engineering service to clients, including:
- Conducting design reviews
- Presenting findings
- Liaise with cross-disciplinary engineering teams and stakeholders.
- Mentor and develop less experienced engineers within the team.
