• Experience in Tax Technology, with a focus on Indirect Tax, e‑invoicing, and/or ERP tax implementations
• Strong understanding of tax processes and how they integrate with ERP and finance systems
• Experience working with technologies such as Oracle, tax engines, or e‑invoicing platforms
• Proven consulting skillset: client engagement, stakeholder management, workshop facilitation, and structured problem‑solving
• Ability to manage multiple workstreams and collaborate across onshore/offshore delivery teams
