Head of Supply Chain

£70,000–£80,000 DOE | Stockton-on-Tees HQ, hybrid | Additional Lengths

Twenty-three years ago, Victoria Lynch turned deep hair extension expertise into a brand. Today, that brand is a multi-channel group serving customers and salons on every continent, growing fast, and about to hand someone the keys to build the supply chain that gets us to our next stage of growth - That someone could be you.

Additional Lengths has grown into one of the UK's leading hair extension specialists — home to , our direct-to-consumer destination for luxury extensions, and Remi Cachet, the UK's number one brand for professional hair extensions. We're headquartered in Stockton-on-Tees with a co-working space in London, and we ship worldwide.

We're a certified B Corp, which isn't a badge we put on a slide — it shapes how we source hair, how we treat suppliers, and how we treat our own people. We were named one of the Sunday Times Best Places to Work in 2024. Our team has more than doubled in recent years, we turned over £25m+ last year, and we're mid-expansion into new international markets right now.

Growth like that puts real pressure on supply chain. That's exactly the problem we're hiring you to solve.

Right now, demand planning, procurement, inventory and warehousing all sit in different hands. We're bringing all of it under one owner — you. You'll report to our Operations Director, lead a Demand Planner and a Warehouse Manager, and carry accountability for cost-to-serve, product availability and working capital across the whole group.

This isn't a role where you inherit a finished machine and keep it running. You're building the engine room for a business heading well past where it is today — new markets, new channels, and a lot more volume than we're moving now.

• Significant supply chain experience across procurement, inventory and fulfilment/logistics in e-commerce, retail, beauty or consumer goods

• Strong commercial acumen — you negotiate with margin, cost and cash in mind

• Experience running a warehouse or 3PL operation and leading an operational team

• Comfortable operating hands-on in an SME with a small team — this is a build role, not a maintain role

• Genuinely tech-savvy: fluent in Excel/Sheets, confident with WMS, ERP and ecommerce platforms like Shopify, and keen to shape how our tools evolve, not just operate what's already there

• A track record of measurably improving availability, forecast accuracy and cost-to-serve

• Experience running S&OP or similar, working closely with a demand planning function
