About The Position

We’re looking for a commercially minded, operationally rigorous Supply Chain Planning & Purchasing Manager to own our end-to-end S&OP cycle — translating demand signals into accurate forecasts, material and inventory plans, weekly purchasing across our supplier base, and clean outbound fulfillment across our 3PL partners. The business currently processes roughly 2,500 outbound orders per week — each carrying 10 to 21 line items — across a catalogue of up to 80 active SKUs. That volume is growing. You won’t just keep this engine running; you’ll build the systems, processes, and supplier relationships needed to scale it reliably.

Requirements

3–6 years in supply chain planning, materials management, or purchasing in a product-based business
DTC cold-chain distribution experience across inbound, storage, and outbound shipping
Proven ownership of an S&OP or IBP process, including demand forecasting and inventory planning
Hands-on experience placing and managing purchase orders across multiple suppliers on a recurring weekly cadence
Experience managing or closely coordinating with 3PL fulfillment partners
Strong Excel / Google Sheets modeling; comfortable with large data sets and pivot-based analysis
Experience using an ERP as a core planning and purchasing tool (OMS module development a plus)
Excellent organizational discipline and attention to detail; able to manage competing weekly deadlines without dropping threads

Nice To Haves

High-SKU, high-order-frequency experience (e-commerce, frozen food, or consumer goods)
CIPS, APICS CPIM, or equivalent supply chain / procurement qualification
Track record building or improving S&OP processes in a scaling business (Series A–C or high-growth SME)
Familiarity with WMS portals and 3PL SLA frameworks

Responsibilities

Own the weekly S&OP cycle — facilitating cross-functional review of demand forecasts, supply constraints, inventory positions, and order cover
Develop and maintain rolling DTC demand forecasts by SKU and by supplier, incorporating sales pipeline, promotional calendars, and seasonality
Establish inventory targets (safety stock, reorder points, min/max levels) across up to 80 SKUs, balancing service level against working capital
Identify and escalate supply risks, stock-out exposure, and overstock scenarios before they impact fulfillment
Generate and place weekly purchase orders across up to 10 suppliers, aligning order quantities with demand plans, MOQs, and lead times
Own the DTC cold-chain packaging lifecycle — sourcing, development, and buying — balancing storage costs against volume pricing breaks
Maintain accurate supplier master data: lead times, pricing, MOQs, payment terms, and contact hierarchy
Track open POs through to receipt, proactively managing exceptions, short-shipments, and substitutions
Manage inbound shipments from suppliers and support onboarding of new vendors
Develop supplier scorecards and run regular performance reviews (OTIF, fill rate, quality compliance)
Serve as the primary operational contact for 3PL partners — managing inbound receipts, outbound order releases, and stock reconciliations
Coordinate weekly order-release schedules across 3PL nodes to meet outbound commitments of ~2,500 orders per week
Monitor fulfillment accuracy, pick rates, and carrier SLAs; escalate deviations and drive corrective action
Partner with 3PLs on capacity planning for volume growth and peak trading periods
Minimize inventory holding costs by maximizing turns
Own the integrity of supply chain data across the ERP / WMS / OMS ecosystem — item master, BOM, and stock records
Own inventory transaction processing end-to-end, from raising POs to item receipt
Build and maintain planning tools and dashboards (Excel, BI tools, or dedicated planning software) to support the S&OP process
Define and track KPIs: forecast accuracy, inventory turns, OTIF, order fill rate, stock cover, and supplier lead-time adherence
Identify system gaps and champion the process improvements and platform upgrades needed to scale
