What You Will Do

• Own end-to-end cost controlling across the group, including OpEx, CapEx, headcount/personnel costs, vendor spend, and technology/infrastructure costs.

• Partner with product and engineering teams to track project developments, assess capitalization criteria, and support strategic discussions on team and asset structuring across entities.
• Prepare annual memos and documentation for the Annual Group Audit and act as the primary point of contact for auditors on cost capitalization and OWC-related matters.

• Partner with Finance Operations and Group Accounting to ensure clean cost coding, accurate accruals, and a smooth and timely month-end close.
• Strengthen cost controls, approval workflows, and policies to protect margin while enabling the business to move fast.
• Support finance leadership with ad hoc projects, analyses, and strategic initiatives as required.
