Head of Indirect Tax

Oxford Nanopore is seeking a Head of Indirect Tax to join its Finance team in Oxford. Reporting to the Group Financial Controller, this is a Director or Associate Director level opportunity (depending on experience) with responsibility for the end‑to‑end governance, control and compliance of indirect taxes across the global group. Please note this role involves hybrid working, with 3 days per week expected at our office in Oxford, OX4.

The Head of Indirect Tax will own the design, implementation and effectiveness of the global indirect tax control framework, ensuring indirect tax obligations are accurately reported and discharged across all jurisdictions. The role oversees a high‑volume filing environment of approximately 700 returns annually through a scalable, system‑enabled operating model. Acting as the Group’s subject‑matter expert, you will provide practical, commercially aligned advice on indirect tax implications relating to strategic and operational decisions, including international expansion, supply chain design and regulatory change. You will also support the Group Financial Controller and CFO in meeting Senior Accounting Officer (SAO) obligations through robust processes, clear documentation and proactive risk identification and escalation. Operating within a lean structure supported by automation (D365 MTD) and third‑party tools (Vertex), the focus is on oversight, exception management and resolution of complex issues rather than transactional processing.

• Operate within a system‑enabled compliance model, leveraging automation and third‑party solutions to deliver scalable compliance.
• Partner with Finance Systems to support implementation, optimisation and ongoing integrity of tax configurations.

• Advisory & Strategic Support

• Provide clear, practical advice on indirect tax implications of commercial transactions, supply chain design, international expansion and market entry.
• Lead indirect tax input into key projects, including new entity set‑up, e‑invoicing and digital reporting initiatives.
• Draft and maintain tax requirement documentation for new jurisdictions and major projects.
• Anticipate and manage the impact of regulatory change, ensuring the Group remains compliant and well‑positioned.

• Leadership & Stakeholder Engagement

• Lead and develop the indirect tax capability, including coaching and development of team members.
• Promote strong awareness of indirect tax risks and controls across the business.
• Build effective relationships and deliver training and guidance across Finance and Operational teams (AR, AP, Logistics and Credit Control) to ensure consistent application of tax principles.
