• Inclusive Culture - A professional environment that values diversity, innovation, and collaboration.

Responsibilities will include:

• Maintain accurate material, demand and stock visibility.
• Plan, monitor and coordinate material availability for test, trials, development and production requirements, escalating risks where material availability may impact programme delivery.
• Manage item master data and new part introduction processes, ensuring all material, planning, sourcing, and inventory attributes are correctly established.
• Work with other departments to understand upcoming hardware requirements.
• Manage conflicting material priorities.
• Raise demand on Procurement where material is required but not available, ensuring requirements are clear, justified and aligned to programme or operational priorities.
• Review bills of material, demand signals, stock records and open purchase orders to identify BOM errors, shortages, surplus, allocation conflicts and potential schedule risks.
• Liaise with Procurement to support expediting, shortage resolution and prioritisation of critical materials required for test, trials, development and production activities.
• Support production kitting and material readiness reviews.
• Maintain accurate records.
• Identify and escalate material risks, data quality issues and process gaps.
• Provide regular updates to stakeholders.
• Ensure all material planning activities are conducted in accordance with company policies, procedures, governance and security requirements.

Qualifications and Experience:

• Experience in material planning, production planning, supply chain, stores, inventory control or a similar role within a manufacturing, engineering or programme environment.
• Experience using ERP or MRP systems, ideally Infor LN, managing demand, stock records, transactions, purchase order visibility and material availability.
• Good understanding of bills of material, demand planning, stock control, kitting, shortages management and material allocation processes.
• Ability to work with competing priorities and make clear, structured recommendations where material is constrained or demand is changing.
• Strong analytical, problem-solving and organisational skills.
• Experience in marine, defence, aerospace or complex engineering environments would be advantageous.
• Relevant qualification in supply chain, logistics, production planning, business, engineering or equivalent experience would be desirable.
