Senior Demand & Merchandise Planner

Make Your Mark as an Demand Planner at Storio group

About the role

Storio Group produces millions of personalised photo products every year across brands like Photobox, Hofmann, and Albelli. Our business is highly seasonal and promotional, and planning is how we stay ahead of it. Everything we sell is made to order. We turn sales data and commercial insight into forecasts of sales, volume and ASP that give the business sales and margin visibility and drive stock and production capacity decisions across Europe.

As Senior Demand & Merchandise Planner, you will be a core Subject Matter Expert in our rapidly developing S&OP function. Reporting to the Head of Demand Planning, you will bridge top-line commercial forecasts with item-level operational reality. You will validate B2C category sales, volume and ASP forecasts, own the sub-category and item mix beneath them, establish B2B forecasting, and improve forecast phasing across our peak cycles. This is a high-impact role where you will build quality into our planning process and support commercial and operational readiness.

How you embrace curiosity daily

Make your mark by taking on these core day-to-day responsibilities:

Validate and check Commercial & Marketing's monthly, weekly, and daily category top-line forecasts of sales, volume and ASP against run rates, promotional plans, and customer strategies

Challenge forecast assumptions constructively across key markets and products, including mix and ASP shifts, when inputs diverge from historical trends or operational reality

Own the detailed item planning process, splitting category forecasts into granular sub-category and item variant forecasts across sales, volume and ASP, providing item sales mix and margin visibility, and Operations with accurate production requirements

Decompose forecasts into their parts (baseline, commercial initiatives and new products), so each can be challenged and tracked

Drive continuous improvement in weekly and daily forecast phasing, reviewing and validating sales forecasts against promotional mechanics, seasonal uplift spikes, and Last Order Dates for key gifting events

Build pragmatic models and tools that help forecast owners submit higher-quality phasing inputs

Take end-to-end ownership of forecasting for B2B vendors, integrating these streams into the central S&OP process
