Mechanical Integration Engineer

Mechanical Integration Engineer | Defence & Autonomous Systems | West Wales | Hybrid | Up to £75,000

We're working with a fast‑growing defence and autonomous systems company based in West Wales, developing cutting‑edge UAV and autonomous platform technology. As they scale their engineering capability, they're looking for a Mechanical Integration Engineer to step into a senior technical leadership position within the team.

This is a rare opportunity to join a business at an exciting stage of growth — where your work will have real visibility and genuine impact on the platforms being built.

The Role

You’ll be the technical authority for mechanical integration across UAV and autonomous systems programmes, leading the way on how subsystems come together as a cohesive, deployable platform. Working closely with systems, electronics, and software engineering colleagues, you’ll own the mechanical integration process from design intent through to physical delivery.

What You’ll Be Doing

• Leading mechanical integration activities across UAV and autonomous platform programmes
• Managing mechanical interfaces between subsystems, ensuring fit, form, and function across the full assembly
• Driving integration planning, defining interface control documentation, and resolving cross‑discipline clashes early
• Acting as a technical point of contact for integration challenges within a growing engineering team
• Supporting testing, build, and verification activities to ensure platforms meet programme requirements
• Collaborating with internal teams and external suppliers to maintain integration integrity throughout the development lifecycle

What We’re Looking For

• Proven experience in mechanical systems integration, ideally within defence, aerospace, or autonomous platforms
• Strong understanding of how mechanical, electrical, and software subsystems interact at a platform level
• Experience managing mechanical interfaces and contributing to or owning interface control documentation
• Comfortable operating in a hands‑on, fast‑paced engineering environment
• A natural technical leader – someone who can bring structure and clarity to complex integration challenges
• Eligibility for SC security clearance (British nationality or long‑term UK residency required)

Nice to Have

• Background in UAV, drone, or autonomous ground/air vehicle programmes
• Familiarity with MoD or defence programme environments
• Experience supporting physical build, rig, or flight test activities

What’s on Offer

• Salary up to £75,000 depending on experience
• Hybrid working with a base in West Wales
• A senior, influential role in a team that’s growing fast
• The chance to work on genuinely complex, meaningful autonomous systems technology
