SIOP Analyst

Job Introduction

Are you passionate about turning data into insight that drives real business decisions? This is a fantastic opportunity to join a nationally critical planning function at the heart of our organisation.

As an SIOP Analyst, you’ll play a pivotal role in shaping how we balance customer demand, operational capability and financial performance. Sitting at the centre of our national Sales, Inventory and Operations Planning (SIOP) process, you’ll work with teams across commercial, supply chain, operations and finance to deliver accurate, trusted plans that inform senior decision-making and support sustainable growth.

This role is ideal for a detail-driven, analytically curious professional who enjoys working with complex data and making a visible impact on business performance.

What you’ll be doing

In this role, you’ll be responsible for supporting the end-to-end monthly SIOP cycle and providing high-quality insight to senior stakeholders. You’ll:

• Gather, validate and consolidate demand, supply, inventory and financial data to ensure accuracy and integrity across the SIOP process
• Analyse forecast accuracy, identify trends and root causes, and provide recommendations to improve planning performance
• Reconcile demand and supply plans, identifying risks, constraints and opportunities ahead of pre-SIOP and executive SIOP forums
• Support the structured monthly SIOP cycle, coordinating inputs, preparing meeting materials and tracking agreed actions
• Develop and maintain Power BI dashboards, executive summaries and MD-level packs that translate complex data into clear, actionable insight
• Analyse inventory levels, production requirements and stock risks to support optimisation and operational planning
• Monitor volume profiles and transport capacity, highlighting opportunities to improve logistics efficiency
• Work closely with commercial, supply chain, operations, finance and MESS colleagues to align plans and resolve data conflicts
• Track planned versus actual performance, producing variance analysis and highlighting areas for management focus
• Support continuous improvement by enhancing planning processes, automating reporting and improving data flows, including the use of Anaplan and Power BI
• Respond to ad-hoc analytical requests and communicate insights clearly to a range of stakeholders

Skills & behaviours

• Exceptional attention to detail, with a strong focus on data accuracy and quality
• A naturally curious, analytical approach and the ability to get behind the numbers
• Strong organisation skills and the ability to manage multiple workstreams to tight deadlines
• A collaborative, proactive style, with confidence working across functions and levels
• Clear communication skills, with the ability to explain complex analysis to non-technical audiences
• Resilience and adaptability in a fast-paced, cyclical planning environment

Experience & background

• Experience in supply chain planning, demand planning, operations analysis or a similar analytical role
• Strong experience in data analysis, reporting and visualisation
• Advanced Excel skills and experience using business intelligence tools such as Power BI or Tableau
