What are we looking for

The Manufacturing Process Engineer (Final Assembly) is a key member of the Production Engineering team responsible for supporting the development, industrialisation, and continuous improvement of assembly processes across manufacturing areas.

The role focuses on delivering robust, repeatable, and scalable assembly processes that support industrialisation and high‑volume manufacturing. This includes development of assembly methods, support of both manual and automated assembly operations, and continuous improvement of production performance.

A key aspect of the role is working closely with Principal Engineers, Automation Engineers, Technicians, and Quality teams to translate manufacturing requirements into effective and stable assembly processes. The engineer will also contribute to process definition, troubleshooting, and optimisation activities during ramp‑up and production.

The role supports multiple assembly operations and plays a critical part in ensuring processes are stabilised, improved, and ready for scalable production use.

Responsibilities

• Lead the industrialisation and ramp‑up of new assembly processes and equipment into production.
• Support the introduction and commissioning of new manufacturing machines and technologies.
• Ensure smooth transition of processes from development into stable production.
• Define, update, and optimise assembly methods, process flows, and standard operating procedures following equipment or process changes.
• Work closely with Automation Engineers and suppliers during equipment integration and commissioning phases (FAT/SAT).
• Identify, evaluate, and implement process improvements driven by development feedback or production requirements.
• Support process validation activities to ensure new and modified processes meet quality and performance requirements.
• Drive continuous improvement initiatives linked to process changes, new technologies, and industrialisation projects.
• Analyse production data to support ramp‑up performance and process stabilisation.
• Collaborate with Quality Engineering to ensure robust introduction of new processes and resolution of related issues.

About You

Knowledge and Experience

• Degree or equivalent qualification in Mechanical, Manufacturing, Industrial Engineering or Mechatronics (HND/HNC with relevant experience also considered).
• Minimum 5 years' experience in manufacturing engineering with proven experience in industrialisation/NPI.
• Experience in manufacturing, production engineering, or industrialisation environments, ideally involving assembly processes.
• Strong understanding of assembly methods, production flow, and process optimisation in manufacturing environments.
• Experience supporting introduction and ramp‑up of new equipment or manufacturing processes into production.
• Experience working in cross‑functional engineering teams including automation, quality, and production.
• Ability to analyse production data and identify process improvement opportunities.
• Experience in troubleshooting manufacturing or process‑related issues in a production environment.
• Understanding of automated and manual assembly environments, with ability to work across both.
• Experience supporting process validation, standardisation, and continuous improvement activities.
• Experience working with equipment suppliers or engineering teams during industrialisation or process change projects.

Skills And Abilities

• Strong ownership mindset with ability to work independently and take responsibility for assigned tasks.
• Highly practical, hands‑on approach with strong problem‑solving attitude.
• Proactive and curious mindset with willingness to learn and continuously improve.
• Structured and logical thinking when approaching technical and operational challenges.
