About the opportunity

You will report to the Senior Manager – Network Modelling & Optimisation, this role will play a pivotal part in shaping the future of our logistics network. You'll not only build and analyse complex cost models but also apply advanced optimisation tools and techniques to deliver actionable solutions that drive efficiency and value across our operations.

This is a hands-on, high-impact role for someone who thrives on solving complex, ambiguous problems, and is comfortable working with large, messy datasets. You'll collaborate with stakeholders across the business, interrogate data, and use your insights to influence strategic decisions at scale.

What you'll deliver with us

• Apply and use optimisation tools and techniques to identify, prioritise, and implement cost-saving solutions.
• Conduct scenario analyses and use geo-spatial data to inform network design and investment decisions.
• Gather, clean, and analyse quantitative cost data (e.g., transport costs, machine outputs, resource allocation) to support operational and financial decision-making.
• Present detailed reports and recommendations to senior management and stakeholders.
• Collaborate with a broad range of stakeholders, including network development, finance, digital/data teams, and external partners.
• Lead and embed a culture of continuous improvement, safety, and customer focus across the function.

About you

You're an energetic, adaptable problem-solver with a passion for optimisation and a knack for turning data into actionable insights. You're financially literate, comfortable with economic drivers, and able to build and interrogate models that deliver real-world impact—even when the data isn't perfect.

You will also have:

• Experience applying optimisation techniques and using insights to drive solutions, including geo-spatial analysis.
• Strong stakeholder engagement skills, with the ability to work across teams and influence outcomes.
• A passion for learning, problem-solving, and continuous improvement.
• Desirable: Tertiary qualification in Logistics, Supply Chain Management, Industrial Engineering, Operations Research, Mathematics, Financial Modelling, or a related field. PhD-level qualifications highly regarded.
