Job description

SIMONMILLER is looking for a hands‑on Demand / Inventory Planner to join our team and own demand and inventory planning across all channels: e-commerce site, marketplaces, wholesale, and retail. You will manage and analyze inventory: needed, current, and projected. You'll work directly with Merchandising, Sales, Operations, Production, Retail, and Finance - this is a highly visible seat with real influence over how the business buys and grows.

About Us

Welcome to our playful world of luxury. We are a lifestyle brand featuring ready-to-wear, footwear, bags, and jewelry. With collections that balance the bold and the timeless, SIMONMILLER epitomizes the vibrant and mod lifestyle of our CEO and Creative Director, Chelsea Hansford.

What You’ll Do

• Work with Finance to build the 12-month demand forecast across all channels and to update inventory OTB against rolling forecasts


• Establish reporting and proposal framework based on inventory needs, current/projected inventory position (including WIP), and selling trends by style


• Design and implement weekly replenishment for retail stores, marketplaces, and packaging components; own initial inventory allocation including buy and assortment planning for new store openings


• Monitor inventory levels for all channels by style and category to avoid stockouts and overstock


• Orchestrate and manage seasonal buys for each channel (wholesale, ecommerce, and retail)


• Orchestrate and manage ongoing Core buys for each channel (wholesale, ecommerce, and retail) to evaluate cross-channel inventory levels and promote MOQ / delivery date optimization


• Analyze and present reorder opportunities for each channel working with production to understand lead-time, MOQ and margin implications during presentation


• Manage inventory re-order status and combine this information with current inventory positions for a complete picture of committed inventory position


• Own the monthly inventory investment plan and open-to-buy being sure all appropriate data is included in data (orders, POs, cost, etc.), keeping purchasing within plan and aligned to the company's cash plans and working capital targets


• Prioritize and allocate constrained inventory across channels: propose which channel gets the unit when demand exceeds supply and facilitate the transfers with appropriate approvals


• Create SOPs around allocation logic and triggers for approvals


• Inventory health: Drive inventory turns and inventory health - aged and excess stock — and bring liquidation recommendations to Merch and Sales


• Systems & standards: Build the models, dashboards, and automation that run planning, plus the master data and process standards behind them

Who We’re Looking For:

• Bachelor’s degree required; degree in supply chain management, merchandising, business, economics, or related field preferred


• 4-7 years of industry experience in quantitative analysis, inventory planning and/or forecasting; in a retail, product or e-commerce company


• Ability to build planning process from spreadsheets and BI tools


• Multichannel and multicategory experience— including personally arbitrating inventory allocation between competing channels when supply was constrained


• Ownership of an inventory or open-to-buy budget, with a clear grasp of the working capital and margin implications of planning decisions - able to speak fluently to both sides of a buy call, not just the units


• Apparel experience strongly preferred; otherwise, consumer goods with high SKU counts, seasonality, and frequent newness


• Strong analytical and financial modeling skills with advanced Excel proficiency


• Knowledge of Skypad preferred


• Knowledge of RLM or similar ERP preferred


• Comprehensive understanding of retail math


• Must be a team player, collaborative and works well in small team environment


• Strong communication, analytical, organizational, decision-making, influence, and presentation skills, with composure in fast-paced, evolving environments
