Job Description:

As BeOne Medicines continues to grow its business in Japan and across the Asia Pacific region, we are seeking a Senior Tax Manager, Japan to provide strong local and regional tax leadership and operational support.

The Senior Tax Manager, Japan & APAC will be the regional tax team's senior, hands-on lead for Japan. The role will take primary responsibility for the quality and timely delivery of Japan tax compliance, tax accounting, tax authority matters, transfer pricing execution, and day-to-day tax advice.

The role will also support selected APAC markets and regional projects. Working closely with the Associate Tax Director, global tax teams, Finance, Legal, Treasury, HR, Medical, Commercial, Clinical Operations, and external advisers, the role will translate technical requirements into practical controls, clear decisions, and sustainable processes.

The successful candidate should be technically strong, practical, detail-oriented and digitally capable, with the ability to work fluently in both Japanese and English. This role requires someone who can bridge Japanese local requirements with global tax expectations and help strengthen tax controls, documentation and process discipline.

• Critically review tax returns, calculations, workpapers, and advice prepared by external consultants; challenge assumptions and ensure accuracy, completeness, and consistency before internal approval or filing

• Ensure tax filings and positions are supported by reliable source data, reconciled to SAP and the general ledger, and evidenced through clear, audit-ready documentation

• Provide practical guidance on vendor, healthcare professional, employee, and cross-border withholding tax matters, working with the relevant process owners to establish clear responsibilities and controls

• Coordinate and review benchmarking studies, local files, related-party disclosures, CbCR-related requirements, intercompany agreements, and supporting documentation

• Advise on cross-border payments and transactions, including treaty access, withholding tax, permanent establishment, indirect tax, and other international tax considerations

• Support Pillar Two, supply chain, customs, financing, restructuring, and other global or regional tax initiatives affecting Japan

Business partnering and transaction support

External adviser and stakeholder management

• Manage relationships with external tax advisers, including scopes of work, fee proposals, budgets, timelines, deliverable quality, and performance

• Maintain internal ownership of tax positions and deliverables rather than relying solely on advisers, escalating material issues with a clear recommendation

• Build trusted, constructive relationships with local management and regional and global tax stakeholders

Team support and capability development

• Provide day-to-day technical guidance, review, and mentoring to the Tax Specialist and other team member(s)
