Role Overview

The Head of Supply Chain owns Additional Lengths’ Group supply chain from end to end: aligning supply with the demand plan, purchasing stock on the best terms, holding the right inventory, and optimising our order to delivery process.

The role brings demand planning, procurement, inventory and, warehousing and outbound logistics under a single owner, with accountability for cost-to-serve, product availability and working capital.

Reporting to the Operations Director, the role leads a team, including a dedicated Demand Planner who leads the demand forecast, and Warehouse Manager who leads customer fulfilment and goods in.

Some of the main responsibilities of this role include

• Own purchasing and supplier relationships.

• Manage supplier performance on delivery, quality and defects.
• Oversee inbound logistics, lead times and imports.
• Product quality and ethical sourcing
• Set incoming quality control standards and acceptance checks, with particular rigour on human hair quality.
• Hold suppliers to clear ethical and labour standards, backed by audits.
• Maintain traceability and provenance of the hair, from source to stock, protecting both compliance and the brand.
• Supply risk and resilience

• Develop alternative and second sources for critical lines.
• Maintain contingency and business continuity plans for supply disruption.
• Demand and supply planning (S&OP)
• Own the end-to-end plan with ultimate accountability for it.

Whilst the Demand Planner leads the demand forecast; the Head of Supply Chain owns the supply planning, the balancing decision, and the plan as a whole.

• Chair the monthly sales and operations planning (S&OP) process, reconciling demand, supply, finance, marketing, and commercial into one agreed plan, and own the trade-offs and sign-off.
• Translate the agreed demand plan into the purchasing and inventory plan, allowing supply to meet demand at the right cost and working capital.
• Line manage and develop the Demand Planner and keep demand inputs decision read and the S&OP cadence sharp.
• Inventory and availability
• Set safety stock, reorder points and replenishment policy to maintain availability without overstocking.
• Balance availability against working capital and manage excess and slow-moving stock.
• Maintain inventory accuracy across all existing and future channels and markets, through owned distribution and 3PL partners, including appropriate stock movements.
• Warehousing and outbound logistics
• Line manage the Warehouse Manager and oversee the Warehouse operations, from goods-in to dispatch.
• Set outbound service levels and cost-to-serve targets and select and negotiate carriers.
• Own export and customs strategy and design the fulfilment network and new channels and markets are added.
• Cost, performance and continuous improvement
• Own end-to-end cost per order and per unit and reduce it while protecting service and quality levels.
• Track and report supply chain KPIs.
• Own returns end to end, driving continued improvement in returns rate, processing time and cost.
• Lead improvement initiatives with a costed business case and measurable outcomes.

About You

We’re ideally looking for someone with

• Experience overseeing a warehouse or third-party logistics operation and leading an operational team.
• Comfortable operating hands-on in an SME with a small team.
• Genuinely tech-savvy; fluent in Excel or Google Sheets and confident with supply chain systems (WMS, ERP, and ecommerce platforms such as Shopify), with the appetite and ability to shape how our tools and technology evolve, not only to operate what’s already in place.

• Ideally some carrier and freight negotiation, and international sourcing, imports and exports.
