About the role
A diverse online business operates across multiple jurisdictions worldwide, generating significant tax data-sharing obligations relating to third parties (3P) that sell via marketplaces.
These obligations sit under frameworks such as DAC7, OECD Model Reporting Rules, CESOP, China PN15, Mexico Digital Access, and a growing number of bespoke jurisdiction-specific regimes.
The role supports the worldwide delivery of 3P data-sharing obligations, focusing on reconciliation, data validation, and quality assurance across regulatory submissions covering hundreds of thousands of sellers and material reporting volumes.
In this role, you will partner with ITX teams across Europe and International, working cross-functionally with Tax, FinTech, GTD, and business stakeholders to ensure data submitted to tax authorities is accurate, complete, and reconcilable. You will strengthen reconciliation frameworks, identify data anomalies, and ensure all submissions stand up to internal review and external audit scrutiny.
The successful candidate will be highly data-centric, naturally curious about numbers, and confident questioning what they see before any data leaves the team. They will have experience working with large, complex datasets, an analytical mindset, and the ability to build clear narratives around what the data is telling them.
Key job responsibilities
- Lead reconciliation and data validation across 3P data-sharing submissions globally — across multiple frameworks (DAC7, OECD, CESOP, PN15, MX SAT, ad-hoc jurisdiction requests)
- Perform completeness and accuracy checks at extraction, transformation, and submission stages, including marketplace coverage, currency consistency, scope filters, and quarter-on-quarter trend analysis
- Investigate variances and anomalies between datasets (e.g., reporting outputs vs. independent baselines, current vs. prior periods) and drive resolution to root cause
- Build and maintain reconciliation methodologies that are documented, peer-reviewed, and auditable — strengthening the team’s overall control framework
- Partner with FinTech, GTD, and other tech teams to translate regulatory requirements into data extraction and validation approaches, providing the analytical lens to ensure the outputs match expectation
- Collaborate with business stakeholders across Europe and International to understand reporting obligations, surface data quality risks, and propose improvements
- Support ad-hoc data requests from tax authorities globally, ensuring data shared externally is reconciled, validated, and documented before submission
- Contribute to continuous process improvement — identifying repeatable validation routines that can be standardized, automated through FinTech tooling, or scaled across jurisdictions
