• Prepare clear summary reports for leadership, highlighting risks, progress, and next steps.
• Escalate material issues to Operations and Finance leads as needed.

How Success Will Be Measured

• Accuracy: Live trackers kept up to date with correct reconciliation statuses.
• Timeliness: Quick turnaround in investigations and reporting.
• Impact: Reduction in inaccurate or aged balances across assigned markets.
• Audit Readiness: Full documentation supporting reconciled items and decisions.

Qualifications

What You Bring

• Experience in media operations, reconciliation, or client reporting (agency experience a plus).
• Advanced Excel and data analysis skills.
• Familiarity with media and finance systems (e.g. Prisma, MediaOcean) preferred.
• Exceptional attention to detail, organisation, and accountability.
• Excellent communication skills—able to work collaboratively across teams and geographies.
• Self-starter who thrives under time pressure and manages multiple priorities with ease.

Bonus Points For

• Experience reconciling large transaction volumes.
• Understanding of media planning and buying workflows.
• Exposure to Accounts Payable or vendor statement reconciliation.
• A proactive, solution-oriented mindset with the ability to think critically.
