About the Position

HOLY is growing fast: with new product launches, expanding retail partnerships, and an ever-increasing customer base driving demand across all channels.

To keep pace with this momentum, we’re looking for a Forecasting Manager who will play a key role in ensuring availability and supply chain efficiency across our portfolio. In this role, you’ll build reliable SKU-level forecasts, align them with supplier capacity, and continuously sharpen forecast accuracy in a fast-moving, omni-channel environment.

SKU-Level Forecasting & Analytics

• Create and update 3–12 month rolling forecasts by SKU, channel, and country.
• Analyze deviations, detect early risks/opportunities, and conduct post-mortems after campaigns.
• Build dashboards to track forecast accuracy, inventory health, and business impact.

Retail & D2C Planning Alignment

• Translate sales plans into demand forecasts and align closely on campaign timing.
• Provide clear forecast visibility to Ops and Finance for planning and cashflow.
• Lead cross-functional initiatives to improve forecast accuracy and input quality.

Production & Supplier Collaboration

• Align demand forecasts with supplier capacity, MOQ, and lead times.
• Track supplier performance (reliability, lead times, quality) and share insights with SCM/Finance.
• Flag capacity risks early and recommend supply or safety stock adjustments.

Inventory Optimization

• Maintain target DOH and safety stock levels for all channels.
• Proactively flag SKUs at risk of over- or understocking.
• Recommend balancing actions (e.g. forward production, phasing, slow-mover clearance).

Scenario & Risk Modeling

• Build upside/downside scenarios for major launches and campaigns.
• Quantify supply impact of forecast variability or production shifts.
• Propose contingency plans for high-likelihood/high-impact risks.

Data Stewardship & Tooling

• Maintain and automate forecasting tools and dashboards.
• Ensure ERP/BI data accuracy (master data, lead times, supplier info) with checks and alerts.
• Partner with Data, Ops, and Finance on system improvements and integrations.
