• Significant experience in commercial finance, FP&A or business partnering leadership roles.
• Demonstrable track record of influencing senior stakeholders and executive teams.
• Experience driving change, transformation and performance improvement.
• Strong analytical and financial modelling skills.
• Ability to translate complex data into clear commercial recommendations.

Desirable Experience

• Background within consumer, technology and high-growth businesses.

Within your first 12 months you will:

• Improve forecasting and planning capability across the business.
• Deliver actionable insights into customer, channel and product profitability.
• Establish meaningful KPIs that drive accountability and performance.
• Become a trusted strategic partner to the CFO and executive leadership team.
