We're hiring a technically skilled and tax-aware professional to support a global tax automation platform integrated with a major ERP environment. This role involves managing system accuracy, supporting compliance processes, and ensuring seamless operations between financial systems and tax engines.

Key Responsibilities

  • Provide subject matter expertise across global indirect tax types such as VAT, GST, Sales & Use Tax, and Withholding Tax.

  • Maintain and resolve issues within tax automation tools including rules, jurisdiction mappings, and product taxability.

  • Ensure correct configuration of tax rates, exemptions, and categories.

  • Support integration points between tax engine and ERP platforms (e.g., Oracle Fusion or similar).

  • Oversee compliance-related reporting activities including audit support, accruals, reconciliations, and filing data preparation.

  • Troubleshoot transactional discrepancies and assist users in resolving taxation-related queries.

  • Log, analyze, and prioritize support incidents while maintaining documentation for future reference.

  • Assist in system patching, version upgrades, and testing of tax automation workflows.

  • Monitor system performance and collaborate on optimization initiatives.

Technical & Data Operations

  • Use SQL and reporting tools to perform transaction analysis, validate tax results, and troubleshoot reconciliation issues.

  • Resolve system integration errors including tax calculation failures, incorrect invoice treatments, or missing rate mappings.

  • Maintain and support API-based connections (REST/SOAP) for seamless data exchange between ERP and tax systems.

  • Improve system throughput by identifying slow processes, batch job delays, and misconfigured data loads.

  • Work with ERP tools (e.g., FBDI, ADFdi) to upload and manage tax data such as exemptions, rates, and transaction records.

Your Background

  • Experience in supporting global tax automation platforms, ideally integrated with cloud ERP systems.

  • Understanding of indirect tax principles across various jurisdictions.

  • Proficiency in SQL for data investigation and reporting.

  • Hands-on experience in system-to-system integration and API troubleshooting.

  • Ability to support both functional users and technical teams across finance and IT.

  • Strong analytical thinking with attention to accuracy in tax calculation workflows.
