Contract Manufacturing Engineer

Job Title: Contract Manufacturing Engineer - NPI

Location: Loudwater, Buckinghamshire

Salary: £40 to £50 per hour

Employment Type: Contract

IR35: This contract does not accept candidates operating through a Personal Service Company (PSC). Therefore, you will be required to work through an Umbrella company.

Are you a Contract Manufacturing Engineer - NPI with strong experience in electromechanical product manufacturing, new product introduction, and low–medium volume, high‑value build environments? We have a 6-9 month contract on offer which gives you ownership of taking complex products from prototype through to stable, repeatable production.

You’ll join a growing engineering and manufacturing function working on advanced electromechanical and electronic systems, where your work directly shapes how high‑value products are built, scaled, and industrialised.

The Role

This is a hands‑on Contract Manufacturing Engineer - NPI position focused on the manufacture, assembly, and industrialisation of complex electromechanical products within a low–medium volume, high‑value production environment.

You’ll work closely with design, production, and test teams to transform evolving prototypes into stable, production‑ready assemblies. You’ll define processes, tooling, and build flows that ensure products can be manufactured reliably, repeatedly, and efficiently.

• Lead the transition of electromechanical products from prototype to full production (NPI)
• Develop and refine manufacturing processes, assembly methods, and build documentation for low–medium volume, high‑value products
• Translate evolving designs into robust, manufacturable solutions with clear production structure
• Work closely with design engineers to improve product architecture, assembly flow, and build quality
• Drive improvements in scalability, repeatability, and manufacturing efficiency
• Support production teams with technical input, troubleshooting, and continuous improvement
• Create work instructions, process maps, tooling requirements, and build standards
• Contribute to ongoing product development with a manufacturing‑first mindset

• Experience as a Manufacturing Engineer within an electromechanical or electronic product environment
• Strong, demonstrable experience with NPI, product industrialisation, and prototype‑to‑production transition
• Experience in assembly processes, build optimisation, and hands‑on manufacturing support
• Ability to bring structure to evolving designs and maturing product architectures
• Practical, proactive problem‑solver with strong communication and cross‑functional collaboration skills
• High‑power electronics, electromechanical assemblies, or complex multi‑part builds
• Experience in fast‑paced development or start‑up‑style environments
• Supporting scale‑up of products into structured low–medium volume production

Please note, this contract does not accept candidates operating through a Personal Service Company (PSC). Therefore, you will be required to work through an Umbrella company.
