Demand & Supply Planner

Location: Solidcor, Chesterfield (On Site)
Type: Full-time, Permanent

IMPACT EVOLVE are proud to be partnering with Solidcor ,a fast-growth UK fire-door manufacturer strengthening its end-to-end planning capability. We’re hiring a Demand & Supply Planner to own the full planning cycle: building a reliable forecast, converting it into a realistic supply plan, and ensuring materials, capacity and production stay aligned.

This is a rare chance to design the entire demand-and-supply rhythm from scratch , creating the tools, cadences and data discipline that will power a scaling manufacturing operation.

Key Responsibilities

Build the End-to-End Planning Engine

• Create a weekly demand → supply → materials → action cycle that the business can rely on.

• Develop monthly forward views for both demand trends and supply/capacity requirements.

• Build and maintain all core planning templates.

Demand Planning

• Own the SKU-level forecast using history, pipeline, seasonality and promotions.

• Track accuracy and bias; communicate shifts early so supply and production can adjust.

Supply & Materials Planning

• Convert the forecast into time-phased supply plans and purchase proposals.

• Maintain rolling materials coverage, identify shortages early and prevent stockouts.

• Manage supplier call-offs, confirmations and escalations with clear options.

Production Alignment

• Translate demand and supply plans into clear build schedules and material requirements.

• Support simple staging/WIP controls to maintain accuracy and flow.

• Run short, focused shortage/expedite huddles to keep production moving.

Process, Data & Inventory Basics

• Own essential planning master data (lead times, multiples, suppliers, statuses).

• Establish simple, reliable inventory practices that feed accurate planning.

Communication & Cadence

• Publish a single, agreed weekly plan across Demand, Supply and Operations.

• Highlight gaps, risks and trade-offs; keep Sales, Ops and the COO aligned on priorities.

Success in the First 6 Months

• A stable demand-and-supply planning rhythm is embedded and trusted.

• Standard orders consistently hit the 10-day OTIF lead time.

• Supply plans are realistic, materials visibility is clear, and late changes drop sharply.

• A rolling 6-month demand outlook and a strong near-term supply view minimise surprises.

• Supplier performance improves with proactive management.

• Inventory accuracy increases, supporting better planning and fewer fire-drills.

What We’re Looking For

• Someone who has built demand and supply planning foundations before — tools, cadences, templates.

• Strong end-to-end planning experience in a high-mix, component-heavy manufacturing environment.

• Able to turn messy data into a clear, joined-up plan across demand, supply and materials.

• Strong Excel/Sheets capability; comfortable with ERP/MRP but not reliant on systems.

• Practical, hands-on and confident working across suppliers, production and sales.

• Clear communicator who can prioritise, push back and make trade-offs visible.

Experience: 4–8+ years in demand, supply or materials planning.

In Return

• Unlimited annual leave

• Private medical after 3 months

• Performance bonus

• The opportunity to build the full demand-and-supply planning function in a scaling operation
