At Nscale, we’re looking for a strategic and hands-on Senior Manager, Tax Compliance & Reporting to drive our global tax compliance, financial reporting, and transfer pricing efforts as we scale across borders.

About The Role

Key Responsibilities

• Manage global tax compliance processes, including corporate income tax filings and other regulatory obligations across multiple jurisdictions.
• Lead global tax reporting and provisioning under US GAAP (ASC 740) and IFRS, including quarterly and annual tax accounting, deferred tax analysis, and FIN 48 positions.
• Support design, implementation, and maintenance of global transfer pricing policies and documentation in line with OECD guidelines and local country requirements.
• Ensure timely and accurate completion of global tax filings, disclosures, and tax authority submissions, working with external advisors and internal stakeholders.
• Coordinate and manage tax audits and inquiries from tax authorities, ensuring risk mitigation and appropriate documentation.
• Partner closely with the broader finance and accounting teams to improve tax-related internal controls, governance, and process automation and technology.
• Support cross-border tax planning initiatives, intercompany transactions, and intra-group service models, with a focus on compliance and reporting accuracy.
• Create and maintain tax compliance calendars, workflows, and systems to improve visibility, efficiency, and control.
• Manage and develop a growing international tax compliance and reporting team, starting with one direct report and expanding as the function scales.
• Stay up to date on evolving global tax legislation (e.g., Pillar 2, BEPS 2.0), and assess the impact on the company’s tax positions and disclosures.

What We're Looking For

• ACA, CTA, CPA, or equivalent professional qualification with a strong tax accounting foundation.
• 8+ years’ experience in international tax compliance and reporting, ideally with in-house experience at a multinational.
• Deep technical knowledge of US GAAP (ASC 740), IFRS, and setting up global tax compliance frameworks.
• Proven expertise in transfer pricing policy documentation, and risk management.
• Demonstrated success managing global tax reporting processes and external advisors.
• Excellent attention to detail, analytical thinking, and communication skills.
• Adaptable and proactive mindset, capable of operating in a high-growth, fast-paced environment.
