About STYRKR

STYRKR is a performance nutrition brand creating clean, science-backed supplements for endurance athletes. In addition to our own products, we run a growing contract manufacturing business across powders and liquids.

With in-house production and a strong vision, we’re scaling fast — and we need a hands-on Production Manager to lead operations on the factory floor.

About the Role

We are seeking a detail-oriented and analytical Inventory Controller to manage and optimise inventory across our fast-paced FMCG environment within the endurance sports nutrition sector. This role is responsible for end-to-end inventory control covering supplier management, raw materials and finished goods stock control, and Sales-to-Operations (S&OP) inventory flow alignment.

The successful candidate will ensure high service levels, optimal stock holding, strong supplier performance, and efficient inventory movement from procurement through to fulfilment.

Key Responsibilities

1. Supplier & Procurement Inventory Management

• Monitor and manage supplier performance including lead times, order accuracy, fill rates, and compliance with service level agreements (SLAs).
• Maintain accurate raw material and packaging inventory levels to support production schedules.
• Coordinate purchase orders based on demand forecasts and production plans.
• Track inbound shipments and resolve supply disruptions or delays proactively.
• Conduct supplier performance reviews and support cost optimisation initiatives.
• Ensure proper documentation, batch traceability, and quality compliance for all incoming goods.

2. Raw Materials & Components Inventory Control

• Maintain optimal stock levels of raw ingredients, packaging materials, and components.
• Set and manage safety stock, reorder points, and minimum order quantities.
• Perform regular stock reconciliations and cycle counts to ensure system accuracy.
• Minimize waste, expiry risks, and obsolescence — particularly for perishable or regulated nutritional ingredients.
• Support new product launches by coordinating inventory readiness with procurement and production teams.
• Analyze usage trends and forecast consumption to prevent stock-outs or overstocking.

3. Finished Goods Inventory Management

• Oversee finished goods inventory across warehouse(s) and distribution channels.
• Ensure accurate inventory records across ERP/WMS systems.
• Monitor sell-through rates and adjust replenishment strategies accordingly.
• Manage batch control and expiry tracking in line with FMCG best practices.
• Optimize inventory turnover and reduce slow-moving or obsolete stock.
• Collaborate with logistics partners to maintain accurate dispatch and inventory records.

4. Sales-to-Operations Flow (S&OP Alignment)

• Align inventory planning with sales forecasts and promotional activities.
• Participate in S&OP meetings to ensure production plans match demand projections.
• Identify risks related to demand spikes, seasonality (e.g., race seasons), and product launches.
• Provide inventory reporting and insights to Sales, Marketing, and Finance teams.
• Ensure smooth order fulfillment while maintaining optimal stock holding levels.
• Support demand planning with accurate historical inventory and consumption data.

Reporting & Analysis

• Produce weekly and monthly inventory performance reports (stock levels, stock turns, fill rate, ageing stock).
• Analyse variances between forecast, production output, and actual sales.
• Track KPIs including inventory accuracy, stock days on hand, and supplier OTIF (On Time In Full).
• Identify continuous improvement opportunities in supply chain processes.

Key Skills & Competencies

• Strong analytical and numerical skills.
• Advanced Excel and ERP/WMS proficiency.
• Experience in FMCG inventory control (sports nutrition, supplements, or food industry preferred).
• Knowledge of batch tracking, expiry management, and regulated product handling.
• Excellent supplier communication and negotiation skills.
• Strong cross-functional collaboration abilities.
• High attention to detail and strong problem-solving mindset.

Qualifications & Experience

• Bachelor’s degree in Supply Chain, Logistics, Operations, or related field.
• 3–5+ years of experience in inventory control within FMCG or food/nutritional manufacturing.

Experience in demand planning and S&OP environments.

• Understanding of GMP, food safety, or nutritional compliance standards is advantageous.

What Success Looks Like

• Zero production downtime due to material shortages.
• High inventory accuracy (≥98%).
• Improved stock turnover and reduced expired/obsolete stock.
• Strong supplier performance and minimal stock-outs.
• Seamless alignment between sales forecasts and operational execution.

This role is ideal for a supply chain professional who thrives in a dynamic FMCG environment and understands the complexities of managing inventory in performance-driven sports nutrition markets.
