• Coordinate US GAAP tax inputs and collaborate with the global tax team on IFRS consolidation and reporting initiatives
• Contribute to broader group tax projects, including automation, Pillar Two, CbCR, and cash tax planning
• Provide informal mentorship to a junior US tax team member in a flat, collaborative structure

Skills & Experience

• CPA strongly preferred (JD/CPA combination a plus)
• 8–10 years of progressive tax experience with a strong US corporate and international tax advisory background
• In-house experience within fintech, financial services, or similarly fast-paced, complex organizations
• Comfortable operating across multiple tax disciplines rather than a narrow specialization
