• Contribute to CRM planning to ensure performance activity is aligned with customer journeys and lifecycle strategy.
• Plan and launch campaigns across channels with clear targets, measurement plans, and tight feedback loops.

• Partner closely with creative teams and creators to brief, refine, and deploy performance-focused assets.
• Track, analyse, and report on performance; translate data into clear actions and recommendations for stakeholders.
• Own channel-level KPIs (e.g. CAC, ROAS, LTV inputs, revenue, contribution) that ladder up to overall business growth.
