This mandate goes far beyond traditional finance leadership—requiring exceptional commercial judgement, operational focus, and comfort navigating complexity at speed.

• Evaluation and execution of “non-standard” commercial projects (e.g., property acquisitions, unique asset evaluations, alternative investment opportunities)
• Detailed financial oversight for both corporate and owner-related initiatives
• Rapid problem-solving and hands-on involvement in day-to-day operations

About You

• Big Four background or equivalent “super-sharp” technical grounding

• Experience with acquisitions, particularly property and asset deals
• Manufacturing knowledge helpful but not required
