Senior Demand Planner

Job Overview

The Senior Demand Planner owns the unit sales forecast and the receipt need that flows from it, end to end, across an assigned set of pillars and collections. You build the bottom-up forecast at the geography level and translate it into the monthly receipt need that buying decisions are built on — and you're accountable for both the accuracy of that forecast and the judgment behind it.

You drive the demand side of the monthly S&OP cycle: presenting your forecast and receipt need at the monthly consensus meeting, walking senior leadership through your assumptions at S&OP, and speaking to any style in your portfolio at a granular level in the weekly trading meeting. Your forecast brings together customer insights, product strategy, market trends, and operational constraints into one coherent demand plan.

Demand in jewelry moves with gifting moments, cultural trends, and input costs that shift with the market — the forecast you own changes shape with it throughout the year.

What you'll do 

• Own the unit sales forecast: Build and maintain a rolling monthly unit forecast at style/color level over a 12–18 month horizon — built net of returns at geography level, and rolled up to total so that aggregate performance never masks a market-level imbalance. Overlay known business drivers from the shared planning calendar: promotions, campaigns, launches, store openings, and key trading periods.
• Translate demand into a receipt dollar need: Convert the unit forecast into the monthly receipt dollar need that Merchandise Planning stress-tests against open-to-buy, and bring it to the consensus meeting with a defensible number and a clear point of view on the trade-offs.
• Manage inventory coverage targets: Own network-level weeks-of-supply and safety stock targets in alignment with Merchandise Planning’s turn goals and Allocation’s in-store average inventory needs, and shape monthly receipts to the seasonal demand curve.
• Drive the monthly S&OP cycle: Own the demand inputs and cadence of the monthly planning cycle — actualizing the prior month, reforecasting on real selling signals, leading the demand consensus meeting, presenting your plan at monthly S&OP, and delivering the locked forecast, weekly disaggregation, and receipt plan on time every cycle.
• Own size distribution curves: Build and maintain the optimal size distribution for every sized style, and recalibrate as the assortment evolves.
• Own forecast accuracy and forecast health: Track actuals against plan at style/color level, distinguishing genuine demand shifts from supply-constrained misses before revising anything downward. Measure both forecast accuracy and directional bias, root-cause the misses that matter, and turn what you learn into a methodology change rather than a one-off correction.
• Forecast across the style lifecycle: Take new introductions from handoff through their first selling period, and carry styles through growth, peak, maturity, and exit with the right forecast and inventory posture at each stage.
• Partner with Supply on inventory risk: Work with Supply as a two-way early warning system on excess, stockouts, delivery delays, and quality issues — aligning on root cause together before adjusting the plan, and adapting the forecast and receipt need when the supply picture changes.
• Make the process better: Continuously evaluate and improve our demand planning process — sharper methodology, better tooling, less manual rebuilding, and planner time spent where judgment actually adds value.
• We're building an AI-fluent organization. We welcome candidates at all stages of their AI journey — what matters is curiosity, a willingness to learn, and an openness to working alongside AI tools as part of how we do our best work.

What you'll bring to the team

• 3–5 years of experience in demand planning, merchandise planning, inventory planning, or retail analytics within a fast-paced retail, DTC, or e-commerce environment — with meaningful time spent owning a forecast, not only reporting on one.
• Strong command of forecasting methodology — baseline and trend construction, seasonal shape curves, comp-style logic, promotional overlays, and safety stock and coverage models — and the judgment to know when a forecast needs adjusting, and by how much.
• Experience operating inside an S&OP or monthly consensus process — building a geo-level plan, presenting it to senior stakeholders, and holding a point of view under challenge.
• Strong cross-functional collaboration and communication — aligning Merchandising, Merchandise Planning, Commercial, Marketing, Finance, Allocation, and Supply partners around one plan even when their inputs conflict, and making complex quantitative work land clearly with non-analytical audiences.
• High ownership, rigour, and a continuous improvement mindset — always looking for a better way to run the process, and comfortable operating at pace as priorities shift.
• Advanced Excel or Google Sheets skills, and comfort working in a demand planning system and a BI tool to build your own analysis without waiting on someone else’s queue. Experience with SQL is an asset.
• Experience in jewelry, accessories, or another category with sized, personalized, or attribute-driven product is considered a strong asset, as is experience implementing or materially improving a demand planning system.
• Enthusiasm for Mejuri’s mission and the customers we serve.

• A minimum of four weeks vacation, plus personal days and three religious/cultural observance days.
• A hybrid work model for all corporate roles
• ‘Mejuri Passport’ which allows employees who meet specific criteria to work in other locations for one month per year.
• Comprehensive medical and dental benefits, including mental health coverage, and generous personal and sick days for our full-time employees. We also offer bereavement leave, including miscarriage and stillbirth support.
• Parental leave salary top-up of up to 80%, as well as a personalized return-to-work transition and accommodation plan for full-time employees.
• A generous product discount!
