Company Introduction
We have an exciting opportunity now available with one of our Telco clients! They are currently looking for a Senior POR Modelling Contractor.

Job Responsibilities/Objectives

Were seeking a senior, hands-on contractor to build, own, and continuously improve the Plan of Record (POR) financial models that inform executive decision-making across our planning horizons (annual, and multi-year). The contractor will establish a single source of truth for POR assumptions, scenarios, risks, and sensitivities, translating complex drivers into clear, actionable insights.

• POR Modelling & Ownership
  • Design, build, and maintain integrated POR modelling
  • Build scenario/sensitivity frameworks (eg, demand elasticity, price/mix, churn/retention, cost inflation, hiring ramp, etc).
  • Establish assumption governance: define data sources, ownership, validation cadence, and change logs.
  • Integrate actuals and variance analysis; reconcile POR vs. Latest Estimate/Budget/Long-Range Plan.
• Stakeholder Management
  • Partner with ELT members, Finance, Strategy, Product, Sales, and Ops to pressure-test assumptions and crystallise options.
  • Manage senior stakeholder expectations, challenge constructively, and drive alignment/decisions under time pressure.
• Process & Controls
  • Implement model standards, documentation, versioning, and handover materials.
  • Define and run the POR calendar (inputs due dates, reviews, approvals).
• Tooling
  • Work primarily in Excel/Anaplan

Required Skills/Experience
The ideal candidate will have the following:

• 10+ years in Strategic Finance/FP&A/Corp Strategy or similar roles with heavy modelling; prior POR/LRP ownership strongly preferred.
• Expert financial modelling: integrated statements, driver-based operational models, scenario & sensitivity analysis
• Senior stakeholder management: proven track record engaging with senior stakeholders; confident facilitator with strong influencing skills.
• Tooling: Advanced Excel, strong PowerPoint; familiarity with Anaplan preferred.
• Data & Controls: Rigorous approach to data hygiene, version control, documentation, and auditability.
• Domain: Experience in Telecom is a plus.
