You’ll sit at system level, challenge design, assess change impact, and manage suppliers. You’ll front milestone reviews, and when something doesn’t stack up, you’ll drive it to a resolution.

This is engineering accountability, not paperwork administration.

What you’ll be trusted with:

• Leading physical domain V&V strategy and certification activity
• Managing Design Verification Plans and requirements traceability
• Assessing design changes and technical risk
• Owning supplier technical progress and compliance reviews
• Logging, tracking and driving resolution of defects
• Supporting CE marking and regulatory documentation

If you’re an engineer who wants to work on real cutting-edge technology, not talk about it, not theorise about it, but actually build it, this is your moment.

The special projects team is not your average engineering division. This is where high-end engineering meets national importance. You will be working with experts in RF, Laser Directed Energy, and Low Observable technology. The kind of work that doesn’t just push boundaries, it redraws them.

Demand is rising, and the stakes are high. This special projects team need a Technical Lead who can step up and deliver when it matters most.

What You Bring

• Strong background in at least one of the following such as high-power RF, electromagnetic modelling, RF testing, or electronic architecture
• Proven leadership, where you have built teams, aligned people, and got results
• Degree in Physics, Electrical, Aeronautical Engineering or similar
• Project management capability, where you understand delivery, and not just design
• A willingness to undergo DV clearance at a later stage

What You Get

Bonus                                                   Up to 21.25%

Pension                                                Up to 14% combined contribution

On-site perks                                        Subsidised meals, free parking, and more

The Reality

This role isn’t for everyone. It’s complex, It’s demanding, and It’s classified. But if you’re the kind of engineer who wants their work to mean something, and you’re ready to lead at the sharp end of innovation, this is where you can step in.

• Managing defects through to successful closure
• Producing technical reports and verification evidence
• Supporting product certification and customer acceptance
• Reviewing engineering documentation and ensuring technical accuracy
• Managing your own work packages, delivering against quality, schedule and cost objectives

What we are looking for

You will likely have experience in several of the following:

• Systems Engineering
• Requirements Management
• IBM DOORS
• Verification & Validation (V&V)
• Systems Integration
• Test Planning and Test Procedures
• Requirements Engineering
• Hardware Integration
• Technical Report Writing
• Configuration Management
• Working within multidisciplinary engineering teams

You will also be confident communicating technical information with engineers, customers and stakeholders, helping drive informed engineering decisions.

What's on offer
