Tax Technology Manager

Role Description

About Booking.com: At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. Through our products, partners and people, we make it easier for everyone to experience the world.

The Role: The Tax Technology Manager will join the Data & Technology Strategy (DTS) team and play a key role in executing Booking’s tax technology roadmap, with a particular focus on e-invoicing, digital reporting and tax data transmission (DAC7, CESOP etc.).

Reporting to the Senior Manager Tax Technology within DTS and sitting within the Tax team at Booking, this role is responsible for translating tax requirements into concrete technology solutions, supporting platform modernization, and ensuring that our tax capabilities are implemented correctly, tested thoroughly, and documented clearly.

You will work day-to-day with FinTech, Project Management and Tax to define detailed requirements, support design, configuration and testing, and help deliver a scalable, governed and reusable tax technology platform ahead of upcoming tax regulations impacting Booking with a key focus on digital reporting and e-invoicing. This is a hands-on delivery role, focused on execution, analysis and subject-matter expertise.

Scope and Impact

• Act as subject matter expert (SME) for e-invoicing, digital reporting and tax data transmission, supporting both discovery and implementation activities across multiple jurisdictions.
• Translate regulatory and tax policy requirements (e.g. ViDA, DAC7, CESOP, e-invoicing regimes) into detailed, tax technology requirements.
• Join industry-wide conversations and broader groups on policy, including engagement with bodies such as the OECD and other organizations.
• Support end-to-end delivery of capabilities related to e-invoicing and digital reporting ensuring solutions are compliance-first, robust, and auditable for current and future tax needs.
• Help accelerate key programs (e.g. ViDA readiness, e-invoicing rollouts) by breaking down tax requirements into implementable user stories, test cases and data mappings, and by supporting cutover and post-go-live stabilization.
• Contribute to future-proof tax solutions and processes that support our broader tax technology roadmap. Optimise our future platform by identifying issues, proposing pragmatic fixes, and promoting reuse and standardization across countries and business models.

Key Responsibilities

Tax Technology (Execution & SME)

• Gather, document and maintain clear tax technology requirements for e-invoicing, digital reporting and data transmission so that engineering, architecture and product teams can implement compliant solutions on time.
• Work day-to-day with cross-functional teams (FinTech, Project Management, Tax, Accounting, Compliance) to translate tax objectives (e.g. ViDA, DAC7, CESOP, local e-invoicing mandates) into detailed process flows and requirements.
• Support the tax technology track in delivering capabilities and jurisdiction go-lives in parallel, with strong emphasis on reusable configuration, templates and patterns to reduce time and effort for each additional country.
• Contribute to build/buy/hybrid decisions for tax technology solutions.

Requirements & Regulatory Change

• Support discovery and design for new tax legislation and regulatory changes (e.g. data elements, timing and frequency of data transmission, invoice/report formats and controls).
• Ensure solutions are designed with AI-compatibility and self-service in mind where relevant (e.g. clear data structures, accessible documentation, robust metadata) and help document trade-offs and design decisions.
• Monitor global regulatory changes in the area of e-invoicing and digital reporting and regularly update leadership and include on roadmaps.

Processes, Controls & Operations Readiness

• Work with Tax, O2C, Accounting and FinTech to ensure compliance processes for e-invoicing and digital reporting are clearly designed end-to-end, documented in process maps, RACIs and runbooks, and tested and operating effectively post go-live before handover to BAU teams.
• Support Project Management and governance forums by providing input into RAID logs, scope documents and decision logs; maintaining tax-technology requirements and configuration inventories; and aligning on dependencies and cutover plans across Tax, FinTech, Accounting and Compliance.
• Coordinate and support external partners and vendors (e.g. tax engine providers, local advisors, integrators) by preparing requirement packs, reviewing deliverables, and following up on open items related to e-invoicing, digital reporting and data transmissions.

Knowledge Sharing & Ways of Working

• Contribute to documentation standards for tax technology (Confluence, repositories, playbooks), ensuring that designs, decisions and configurations for e-invoicing and digital reporting are captured and maintainable.
• Share expertise on e-invoicing, digital reporting and tax data flows with Tax, DTS and FinTech colleagues through training sessions, demos and “how-to” guides.
• Partner with Project Managers to embed best practices in agile delivery for tax technology work (backlog refinement, acceptance criteria, definition of done, proper handover to BAU).

Skills and experience required:

• Experience in tax technology and/or indirect tax in Big 4, consulting, or complex international environments, ideally including e-commerce, platforms or high-scale digital businesses.
• Demonstrable, hands-on experience with e-invoicing and/or digital reporting projects, such as local e-invoicing mandates (e.g. LATAM, EU countries, APAC); ViDA-related changes, SAF-T, real-time reporting, or similar regimes; and platform data reporting obligations (e.g. DAC7, CESOP, local platform reporting).
• Strong background in at least some of: tax engines and tax tools (e.g. Avalara, Vertex or similar); ERP systems and integrations, preferably SAP (S/4, ECC) and/or Oracle; tax-relevant data models, mappings and reconciliations; tax transformation or finance transformation projects.
• Solid understanding of indirect tax regulations impacting digital companies and platforms, and how they translate into data, invoicing and reporting requirements.
• Degree in Accounting, Tax Economics/Law, Finance, Information Systems, Computer Science or a related field.
• Professional tax or accounting qualification is a plus, but not required where strong, demonstrable hands-on experience exists.
• Comfortable working with structured data (e.g. XML, JSON, CSV) and discussing data models, field-level requirements and interfaces with engineering and data teams.
• Experience writing and reviewing business requirements, user stories, test cases and process flows for technology implementations.
• Track record of contributing as a workstream owner or key SME on multi-stakeholder technology programs, ideally in agile or hybrid delivery environments.
• Able to communicate complex tax and technology topics in a clear, structured way to both technical and non-technical stakeholders.
• Comfortable working in a fast-paced, high-pressure environment with multiple parallel deliverables and evolving scope.
• Pragmatic, detail-oriented and execution-focused: willing to dig into the details of data, processes and configuration, while understanding how your work supports the broader tax technology strategy.
