Job Description

Key Responsibilities:

Demand Planning & Forecasting

Own the BusWay demand plan across an 18-month rolling horizon, split between confirmed backlog and weighted pipeline.
Build and maintain the project funnel conversion model with Commercial — win probability, expected award date, expected delivery phasing — validated against historical conversion performance.
Segment demand by customer, sector, project type and geography to expose patterns, concentration risk and growth opportunity.
Establish, measure and publish forecast accuracy and forecast bias at the levels that matter (total BU, segment, key customer, monthly bucket).
Analyse root causes of forecast variance and agree corrective actions with the relevant function, closing the loop rather than reporting the gap.

S&OP Cycle Ownership & Orchestration

Own the end-to-end monthly S&OP calendar: data cut-off, demand review, supply and capacity review, pre-alignment, and the executive S&OP meeting chaired by the Supply Chain Manager.
Prepare and issue the S&OP pack and pre-reads ahead of every meeting, with the analysis complete and the decisions required clearly framed — the meeting is for deciding, not for discovering.
Facilitate the demand review with Commercial and the supply review with Production and Planning, aligning as much as possible ahead of the executive session.
Frame the gaps, risks, options and trade-offs for decision, with a recommended position and the consequence of each alternative quantified.

Business Operating Plan (BOP) & Financial Integration

Lead the supply chain contribution to the annual Business Operating Plan: volume, capacity, inventory and working-capital assumptions.
Work with Finance & Accounting to translate the volume and mix plan into the revenue and cost plan, ensuring supply chain and finance operate from a single set of assumptions.
Maintain a rolling re-forecast against the BOP and quantify the variance drivers — mix, timing, conversion, capacity, price.
Model the working capital consequence of the plan: inventory requirements, copper and aluminium exposure, cash phasing against project milestones.
Support commercial and investment decisions with quantified analysis: capacity investment cases, make-vs-outsource, project prioritisation, order acceptance under constraint.
Provide the volume and mix inputs required for capacity, headcount and capital planning across the supply chain.

Supply, Capacity & Constraint Planning

Translate the demand plan into a Rough-Cut Capacity Plan (RCCP) against production capability, identifying bottlenecks early enough to resolve them.
Balance demand against capacity, material lead times and project milestone commitments, and present feasible options where they compete.
Work with Material Planning on the long-lead and high-value material implications of the plan — particularly copper and aluminium volumes, timing and price exposure.
Provide the agreed, single demand signal that Material Planning, Production Planning, Warehousing and Logistics plan against.

Cross-Functional Interface & Governance

Act as the primary supply chain interface to the Commercial team on demand, order intake, customer commitments and delivery expectations.
Partner with Project Management on project milestone dates, delivery phasing, item list release timing and revision impact.
Partner with Finance & Accounting on volume, revenue, inventory, working capital and variance analysis.
Define and maintain the gives-and-gets: what each function provides, in what format, by what date, and what it receives in return.
Work proactively across functions to align inputs and data, engaging the Supply Chain Manager where a decision or arbitration is required.

Planning Systems, Data & Reporting

Establish and own the planning data model — the single source of truth for demand, backlog, capacity and plan-versus-actual.
Build and maintain planning tools, models and dashboards (advanced Excel and Power BI or equivalent) that make the plan visible and self-service across functions.
Design and implement structured, systematised, ERP-integrated planning processes and tools to support the business unit's growth trajectory.
Identify and lead automation and digitalisation opportunities across the planning process.

Process Development & Continuous Improvement

Design, document and maintain SOPs and work instructions for demand planning, S&OP and BOP processes.
Build the planning capability of the wider organisation — engage and coach Commercial, Production and Project Management stakeholders on their role in the cycle.
Benchmark against S&OP and IBP best practice and drive a staged maturity roadmap.

Job Requirements:

Bachelor's degree in engineering industrial, Production, Mechanical or any related field.
4–6 years in supply chain planning, with demand planning, S&OP or integrated business planning as a named, owned part of your role.
Experience running or co-running a structured planning cycle — owning the calendar, building the pack, presenting to senior stakeholders and driving actions to closure.
Experience owning forecast accuracy and bias, with evidence of having improved them.
Experience in a manufacturing environment.
Advanced Excel — modelling, scenario analysis, large data sets.
The ability to engage and constructively challenge senior stakeholders with data.
